Hopefully, this will work finally and save room in the process….Week 5 Blog post (2)

 

 

Taking this idea from Savannah and linking a pdf with all of my work from those first 5 chapters.

Lashway Week 4 Write-Up

Week 5 Work – Savannah Domenech

I hog up much less room this way. Click the text above to view my Week 5 work.

Chapter 1:

• GIS is composed of 5 parts: hardware, software, data, procedures, and people
• Can be used to map relationships, patterns, and trends in addition to simple cartography
• Interesting how GIS has been around since the 60’s. I wonder how difficult it was to use it back then
• Point, line, polygon data = vector data
• Features of same type = layers
• Raster= digital surface
• Attributes= in depth data

• Don’t be like me and do the exercises in the classic map view, and then get confused as to why everything looks different

---

Chapter 2:

Exercise 2A

• PM concentrations are highest in Africa
• To restore contents, go the ‘View’ and select contents
• Geoprocessing toolbox is right next to contents
• Shanghai has the largest population

Exercise 2B

• Symbology= the way GIS features are displayed on a map
• The distance between San Antonio and Toronto is 1,440.32 mi

Exercise 2C

• The highest building is 339.8 ft
• Extrusion= stretching flat 2D features vertically to appear 3D
• This was cool- I felt like I was playing the Sims lol

Chapter 3

Exercise 3A

• The field name that indicates the state within the which the county features are located is called STATE_NAME
• 10575 residents of Wayne county are between 22-29 yrs
• Definition query: limit visible counties to only in Illinois, but source data will not change 
• Clip: Select data based on layer of boundary (However, Illinois boundary not defined)
• Select and export: select counties in Illinois and export to new dataset

Exercise 3B

• Columns= fields
• There are six years of data represented
• Graduated colors= features are assigned a color that represents a quantity
• Classification methods:
  • Manual interval classification
    • Modify classification breaks manually with manual intervals
  • Equal interval classification 
    • Range of data is equally divided by the number of classes chosen
  • Defined Interval Classification
    • Similar to equal interval, but define interval size to determine class number
  • Quantile classification
    • All classes have same number of features
  • Natural breaks classification
    • Based on natural groupings inherent in the data
  • Geometric interval classification
    • Creates class breaks that are based on class intervals with a geometric series

  • Strategic development
  • Violence against civilians
• 727015 fatalities

Exercise 5b 

• 41 riots/protests
• 71 fatalities

Exercise 5c

• Layer by attribute and Summary statistics are combined
• 26323 fatalities 

 

Chapter 1 (Law / Collins)

 

• It is important to note that the feature data in GIS contain attributes that correspond to the features attribute data. 
• Feature attribute information is stored in a table in a GIS database. Each feature occupies a row in the table, and an attribute field occupies a column
• ArcGIS Pro is similar but also different from the basis of ArcMap in that it uses ArcGIS Online basemaps as the backdrop instead of the typical import of basemaps from another source. ArcMap can also use Arc Online for basemaps but this is something that is not extremely important

 

Exercise 1: 

• This figure represents up to the 8th step in exercise one. At this point all that has really been done is opening an ArcGIS online map and seeing some of the features located in the layers tab that are associated with the map

• This figure represents the public schools in the area but with a different symbol. At this point in the exercise we have successfully changed and updated a symbol in the map

 

• The next figure shows the ToBreak attribute and what this attribute shows is the minutes it takes to walk to school from those areas.

• This figure represents the different areas and how long it takes to walk to school from those areas. Using the steps in the book I was able to create this map to show the difference between 5, 10, and 15 minutes of walking to get to school. Red being 5, blue being 10, and green being a 15 minute walk to school. 

• This figure represents the Vision Zero Safety Incidents that were configured using the filter and clustering section of the editing tools for the map. As well as the map pop-up windows were configured to produce this figures pop up window you can see in the top left of the figure.

• This figure shows what the final version of the map looks like with all three layers showing. Cities can use a map like this to create stricter speeding fines and punishments for school zones where these incidents occur. 

 

Chapter 2:

 

• This chapter begins with getting to know the basics of ArcGIS Pro. ArcGIS Pro offers 2D AND 3D visualization and analysis with an interactive, navigable interface.
• So far this chapter is showing that although ArcPro is similar to ArcMap, it varies in that it is more similar in some regards to Microsoft applications

 

• A folder connection was one of the first steps in exercises 2a and this was a very similar process to that of ArcMap
• This figure shows the air pollution by country layer in the first exercise in chapter 2. This map was produced from data that was imported into ArcPro and then manipulated to look the way it does.

• The continents that PM concentrations are the highest are Africa and Asia. 

 

• To restore the contents pane in ArcPRO just go to the view tab and click on contents

 

• The largest city according to the Cities attribute table is shanghai china

• This figure shows what the final map looks like after the first exercise in chapter 2. Some basic tools were used to manipulate the map and its data so that it looked this way as a final product.

• This figure shows what the map looks like at the end of the 2nd exercise in chapter 2. In this exercise we changed feature symbols, configured feature labels, used the measure tool, added a cloud-hosted basemap, and packaged the project to share online.

 

• The height of the tallest building in the third exercise in this chapter is 339.76 feet

• This figure shows the final map image for the final exercise in chapter 2. In this exercise we learned how to convert a 2d map into a 3d map, and then extrude features based on the building height attribute to visualize buildings in a more realistic perspective. This exercise was fantastic if I say so myself and I was genuinely surprised going through this chapter. I think chapter 2 contained great information that is vital in getting to know ArcPro.

 

Chapter 3:

 

Questions :

• (add data to the project) The field name that indicates the state within which the county features are located is called STATE_NAME
• (add data to the project) There are 10575 residents in Wayne County Ohio between the ages of 22 and 29
• (Incorporate tabular data) Six years of data are represented in the table
• (incorporate tabular data) No I do not see a correlation between income and 2010 obesity rates. There are many counties with moderate-high income and high obesity rates. There are also counties with low income that have moderate to low obesity rates.
• (Calculate data statistics) 18.7% of households had an income of less than 15,000 per year.
• (connect spatial datasets) There are 4 food deserts in knox county

• This figure shows the map after the first exercise in chapter 3. This map was configured using select features by attribute and then exporting those features into a new dataset into the map.

• This figure shows the final map product at the end of the second exercise in chapter 3. This exercise was all about joining the cdc data to the Illinois county feature class. This was done using a variety of methods and data manipulation techniques including joining data tables, incorporating layer symbology, and using the swipe tool to compare different years of the data on the map.

• This figure shows the final map product after the end of the 3rd exercise in chapter 3. This exercise was all about calculating the data statistics. We added a new attribute field and then populated the field with values. We then calculated the summary statistics for the state.

• This figure shows the final map product of the last exercise and the final map at the end of chapter 3. This exercise was all about spatially joining data. We spatially joined the 2010 layer with the IL_food_deserts layer and this is shown by the number of food deserts displayed on the map for each county. 

 

Chapter 4:

 

Questions:

 

• (Configure snapping options) The selected line has 4 vertices
• (Modify Features) The Shape_area value decreased from the original water pressure zone

 

• This figure shows the final map product after the first exercise in chapter 4. This exercise was all about switching the city’s data collection to a geodatabase model. It was easier than expected to build a geodatabase for the city.

• This figure shows the final map product after the second exercise in chapter 4. This exercise was all about creating features and fixing the missing water lines in the map. This was done using a variety of techniques in the data tab of the ribbon. Snapping was the method that was used for the exercise.

• This figure shows the final map product of the last exercise and the end of chapter 4. This exercise was all about modifying features which included splitting a polygon, merging polygons, modifying lines and points, and adding map notes.

 

Chapter 5:

 

Questions

 

• (manage a repeatable workflow using task): The conflict events recorded in the dataset are  battle (no change of territory), battle (government regains territory), battle (non-state actor overtakes territory), headquarters or base established, non-violent transfer of territory, remote violence, riots/protests, violence against civilians, and strategic development 
• (Author a task) 14,211 fatalities resulted from violent conflicts against South Sudanese civilians between 2010 and 2018 
• (Run the model) There were 71 fatalities that resulted from conflicts classified as violence against civilians in Rwanda from 2010 – 2018
• (Convert a model to a geoprocessing tool) 41 riots/protests occurred in Rwanda between 2010 and 2018 and 12 fatalities resulted from this
• (Use a custom script tool) The geoprocessing tools combined in this script are Select Layer By Attribute and Summary Statistics
• (Use a custom script tool) 26,323 fatalities resulted from conflicts classified as violence against civilians in Nigeria from 2010 to 2018

• This figure shows the final map product of the first exercise of chapter 5. This exercise was all about using the Tasks pane in ArcPro to establish a workflow for ourselves and so others can use the task we created in a similar way to create a similar map with the appropriate data. 

• This figure represents the final map product at the end of exercise 2 in chapter 5. This exercise was all about using ModelBuilder which is a design environment for creating spatial analysis workflow diagrams and in this exercise we used ModelBuilder to build the workflow to create this map.
• Here is the final modelbuilder model in ArcGIS Pro
• 
• This figure shows the final map product of the last exercise in chapter 5. We can see that all three countries (South Sudan, Rwanda, and Nigeria) are highlighted as they were all worked on in different exercises throughout the chapter. This exercise was all about running geoprocessing tools in ArcGIS Pro using Python. This workflow was similar to the first two exercises but we used Python coding and a script tool to execute the processes. 

Notes:

• These first five chapters of the book were very informative on how to use the tools and functions in ArcGIS Pro, and how to manipulate maps and data as well. Once we get to chapter 3 I think that’s when things start to get dicey. Although I can follow the instructions the book gives for each exercise in each chapter, I would still struggle somewhat if I were to do this off the top of my head (guess I need to review more). 

Chapter 1:

 

• Projects: contain maps, layouts, layers, tables, tasks, tools, and connections to servers, databases, folders, and styles – everything you needed stored in one
• Can have maps 2D or 3D, or both simultaneously
• Geoprocessing tools allow you to perform spatial analysis and manage GIS data
• Configure symbology, clusters, and pip-ups to make the data layers and attributes more usable 

 

Chapter 2: 

 

• Content pane allows you to modify map’s layers
• Symbology: the way GIS features are displayed on a map
  • Graduated symbols – are used to represent a range of symbols based on an attribute field, greater the value the larger the symbol
• Learned to import maps, add local data, practiced converting 2D to 3D

Chapter 3:

 

• Using GIS you can combine datasets, enrich them with new attributes, derive statistics from them, and get new information based on their relationships
• Definition query: you can set a definition query limit to limit the visible areas to only those that you choose – help to use when working with a subset of data in a map while maintaining the source data
• Attribute join: you can use this operation to append the spreadsheet table to your existing attribute table – as long as you have a common attribute field in each
• Spatial join: joining data based on location, not common attribute – allows you to define a spatial relationship between two layers
• This chapter is on data relationships

Chapter 4:

 

• Will populate empty geodatabase by converting shapefiles and mapping x,y location values found in nonspatial tables – all outputs will be placed in geodatabase
• Use script tool to convert multiple files at once
• Snapping: is an editing option that acts like a magnet – if point you create is within distance of another feature’s vertex, endpoints, edge, or intersection, it will jump to coincide with another feature

Chapter 5:

 

• Tasks: feature that allows you to use a series of predefined steps that can incorporate commands and geoprocessing tools, including model and script tools
• ModelBuilder: geoprocessing environment that allows you to easily link one tool to another and run a set of operations one after another – provides helpful visual diagrams of geoprocessing workflows
• Python is the scripting language compatible with ArcGIS software
• Model: allows you to string multiple geoprocessing tools together and rin them automatically 

1. Chapter 1
   1. This chapter is all about introducing the beginning aspects of ArcGIS, including reintroducing the vocabulary, concepts, and theories that were introduced in the Mitchell readings. 
   2. Vector data is made from point, line, and polygon data
   3. Features are the aspects of data that you want to highlight, and then the features that you want to group together will be put into a map layer
   4. Features have locational data and attributes, which are the data behind the locations. An example of a feature and its attributes is mapping where trees are in an arboretum, and then including height, species, and bark depth with each tree. 
   5. Vector data works best with boundaries, such as city mapping, buildings, etc. Raster data works the best with things that do not have boundaries, such as natural phenomena. These natural phenomena include wind speeds, elevation, temperature, and precipitation. 
   6. Raster data is the created through a series of cells 
   7. In this chapter, we learned how to open data and familiarize ourselves with map viewer on ArcOnline. We learned skills such as changing symbology, managing clusters, and messing. 
   8. DCPublicSchoolMap
2. Chapter 2 
   1. This chapter teaches the basic technical elements of ArcPro–the desktop version of ArcGIS. These basic technical elements include introducing us to the top ribbon tools and the sections that make it up (map, analysis, view, insert, etc), as well as how to connect a folder to the project and changing the basemap and labels of a map. 
   2. The third exercise kind of branched off of the basics and starting working with more data in order to create a 3D scene. We also learn here how to mess with the set-up of the screen and where to move content panels, catalog planes, and the map plane, which was useful when setting up the dual screen between the 3D city map and the 2D one. 
   3. For some reason, a few of my files didn’t appear when I first connected the folder, so I had to reconnect. I am not sure why, but this problem continued to happen in the following chapters. 
   4. Map1_3D
3. Chapter 3
   1. This chapter was showing us how to make different maps and how to create and use layers. 
   2. In the beginning, the downloaded data from ESRI did not have the .aprx file, so I had to manually add each file by using the Add Data function in the Map panel. This took more time than planned due to the error (I do not know why the .aprx file was missing), but I was able to configure it so that I could use it for the geodatabase skills. 
   3. Next, we learned how to make choropleth maps that represent obesity in the state of Illinois. In particular, we continued practicing with attribute tables and started with the “join” function. 
   4. Question: in what circumstances would I need to package the map for sharing?
   5. Illinois2
4. Chapter 4
   1. In this chapter, we continued with geodatabases, except this time, we learned how to actually make one. Again, the .abrx was missing, so I had to manually include the data once more.
   2.  We also learned how to establish an attribute domain, which limits which attributes are shown in the table. This is an interesting tool because it simplifies the data to what features I actually wanted to focus on. 
   3. We also created line features, which I found to be quite difficult at first. I think this difficulty came most from the little steps that are necessary, and I am mostly new to the software, so it was difficult to locate where each task or icon was. 
   4. Creating and editing the polygons is another skill practiced a lot in this chapter. A note for me in this case is to zoom in (this is common sense really) because I accidentally connected the wrong vertices, and then later on my sketches were a bit off. I believe these will also get better with practice, as these are my first attempts at doing either of those tasks. 
   5. What is the significance behind the titles/names of functions? Map2
5. Chapter 5
   1. In this chapter we learned about different types of commands within ArcPro, and while I was hesitant in the beginning about the difficulty, I was surprised to find it was much easier (not easy though) than I expected. 
   2. Tasks are interesting–With their semi automated nature, they decrease user error, which I think is useful. There are lots of little mistakes that can be made when running this type of software, and when repeating tasks yourself, it can be easy to make one of these mistakes. However, you should carefully look over each segment in building queries within the task because they rely on specific characters or details to actually run. 
   3. *I forgot to export my map from this chapter, but I will add it soon*

Chapter 1

 I actually enjoyed this chapter a lot because it expressed different types of analysis in numerous parts of daily life (%forest, burglaries, parcels near a liquor store, etc) I cannot stress how cool it is that GIS is around us more than just using it for maps and navigation, which was my initial thought prior starting this course. 

Keeping in mind what different types of geographical features are and how they are represented, a discrete feature is a feature that has definite boundaries. An example of this is a lake or a building. Continuous phenomena is something that can be measured regardless of location, so in the book it mentions temperature or precipitation. (no gaps, starts off as sample points.) Lastly, summarized data is the density of individual features within a boundary, the data applies to a whole area, but isn’t really a specified location. (Example: 740 area code is typically in Southeastern Ohio, but it isn’t specific to what county it is in. It could be Guernsey, Belmont, Noble, or even Marion county. It’s more than those counties. I’m just using the example that it isn’t limited to one county.) There are two ways to represent GIS model wise: These are called vector and raster. 

Vector: This is defined using x,y locations in an area which does not have boundaries, GIS then connects these dot-like coordinates to  draw lines and outlines. These dots can be areas, lines, events and of course locations. Main takeaway: Vectors utilize lines as a way to create almost an outline for locations, streams, and areas. ->discrete and summarized data typically

Raster: These are seen as more of a matrix of cells with continuous space. Used in layers, but layers can be added on top of one another and analysis is then done by combining all of the layers to make a new layer that contains cell values. This seems to rely more on scale of the cell, because it changes the layer being analyzed and also the presentation of the map. Main takeaway: cell size should be close to the original scale of the map, because using too large or small of a cell size can cause conflict with information and lack of precision on the map. ->continuous values

Both Vector and Raster: Continuous categories. 

Map projections: locations on the globe, but are translated onto a flat surface like a map (Flat earth vibes, not liking that but okay GIS.) 

• Distorts features and shapes, also measurements of distance, areas that are already established (counties, villages.)

Coordinate system: Uses specific units to target features in a 2D space, as well as the origin of those units. 

Good gravy, this chapter is packed with information 

I liked that it mentioned land use in this chapter, we learned about that in GEOG 347, so that’s rad. 

Chapter 2

Now there is some degree of significance to plotting and mapping things, mainly because when we look at a map, we are looking for something specific, whether it is a similar structure or a pattern that is familiar to us. (When I drive home, sometimes on Apple maps I look specifically for the Y bridge on Zanesville because it is what I use to get into Cambridge, I can see this on a map and in person.) Maps also can be used to determine trends in areas (ex: Police officers investigating crime activity and seeing whether or not it is in the same area or different parts of the city.) 

Maps are dependent on audiences and what issue is being addressed. (I really liked the color palette for the keys, sorry that’s random but it’s very pretty.) Features require locations, and locations require coordinates prior to being typed into a geographical database (so latitude, longitude, and addresses.) 

It’s important to use specific colors that draw attention to different categories on maps, oftentimes soil maps utilize different colors and codes because soil types are fairly wordy sometimes, but they put the full name in the legend/key. (I think back to a time when I was in a soil microbial lab where this person showed us all the soil types in Kalamazoo county. Here’s the website if anyone wishes to take a gander at it, https://websoilsurvey.nrcs.usda.gov/app/WebSoilSurvey.aspx

 After the hour-long talk the person ended it by saying soil doesn’t matter and I wanted to cry. anyways.) Using recognizable features in maps are extremely important to audiences, especially those who live there that are looking for specific rivers, landmarks, maybe a weird statue. Patterns can be seen just by the human eye, but sometimes maps have “easter eggs” for those who may see different patterns, this varies on how meaningful certain details are to people. 

Chapter 3

So why are we actually mapping all details? Shouldn’t we just focus on mapping the most important features out there? NOPE. Everything is significant in some sort of way, and may actually be beneficial to someone. (typically businesses.) You can include and exclude things from maps just by a degree of relevance, because honestly it may be weird to have “how many slugs are in each yard of Delaware, OH” on a map that shows who all has a subscription to oriental trading company (I bet I just unlocked a memory for you, you’re welcome.) In legends, specific things can be shown by having bigger or smaller, or thinner/thicker lines. (Expressed by having big circles as 2501-8000 employees, or very thin lines as unknown fish habitats in streams.) Mitchell describes continuous phenomena as more of a colorful part of the map. Where areas are displayed as graduated colors and surfaces are contoured, or a 3D perspective, but can also be graduated. (Remember my palette comment in chapter 2? I think this is what I meant. My heart and little GIS mind was in the right place.) Typically lighter colors are expressed as little or a lack of in a map, while darker more shaded in colors are seen as plentiful, lots of. I feel you can heavily argue the point made on page 56 of the Mitchell textbook based simply on perspective. Maps can be a way to express data or even trends especially if used in a long term fashion. (Long term deforestation, crop rotation, droughts, maybe long term crimes? Sue me.) 

Counts and amounts:  total numbers. (I actually don’t know what I truly meant by this, but I’m going with it.) 

• Counts: actual numbers
• Amounts: total value associated with each feature
• Can be used for discrete features

Summarizing by area is a bit harder, because counts and amounts throw a wrench in the patterns if areas are different in size (use ratios so this is accurately represented) 

Ratios: Relationship between two quantities and are created by dividing one quantity by another. 

• This evens out differences in areas that differ in size, but this again is the most significant for summarizing by data

• Averages are also good, because it helps compare places that have little features to places that have a variety of features  

Standard classification schemes: 

• Helps group similar values to look for similarities in data (I saw some statistics, gagged, and then moved onto chapter 4.)
• I liked this chapter towards the end because it showed a lot of ways to plot things on a map (I think I saw a pie chart on one page? I saw topography “contour lines” and was very happy about that) 

Chapter 4

Mapping density is very important when it comes to looking at concentrations of features in an area. 

• Useful for census, counties. I think this may also be used on occasion for political party concentrations in certain states?
• Dot maps represent density of individuals locations and is summarized by defined areas
• Divide total number of features or total value  by the area of the polygon=density value

The Dense surface is created via a raster layer and is more blobby (I think of this as when you look at a map when a storm is coming. Is it a cluster of dots coming at your town or is it a huge blob?

Be careful with dot patterns, they should be an appropriate size for the areas on the map. Too small or too large can obscure patterns which messes up the point the map was trying to make. 

• Search radius: larger it is, more generalized patterns in density surface will be
  • Consideration of more features when calculating value of each cell 
  • Number of features is divided by a larger area
  • Smaller search shows more localized variation, but broader patterns in the data may be shadowed because of small radius
• Calculation method: Uses one of two methods 
  • Simple: counts features within radius of each cell, which forms ring like structures that overlap each other 
  • Weighted: Mathematical function to give more relevance to features closest to the center (No edge effect here) Smoother and more generalized density surface. Maybe easier to interpret.

Units allow you to specify areal units you wish to use for density values. 

•  If areal units are different, values in legends may be extrapolated. (may predict hypothetical values that fall outside the specific data set.) 

Main takeaway from this chapter: A map is so much more complicated than I ever anticipated in my lifetime, there are so many factors that go into this and I didn’t even know you could incorporate standard deviation into a map. That’s insane, mapmakers are insane.

Getting to Know ArcGIS Chapter 1

Notes and Comments:

• GIS is composed of five interacting parts: hardware, software, data, procedures, and people
• Spatial data is information that represents real-world locations and the shapes of features at those locations and the relationships between them
• GIS, like mentioned in the Mitchell book, is a visual, quantitative, and analytic tool
• Geoprocessing is the manipulation of spatial data
• Open data allows anyone to get authoritative data and information. ArcGIS Hub is a way the public can freely access maps and data
• I find the concept of open data fascinating as one of the goals of it the book mentions is the ability to get right to problem-solving. We have so much data, especially in research papers, but I feel that it is hard to take action
• It’s good to keep in mind that ArcGIS Desktop is a suite and not just confined to ArcMap and that ArcGIS Pro is part of the ArcGIS Desktop suite

Exercise Notes and Screenshots:

• I couldn’t find the outline toggle in step 12 of Configure the map symbology so I skipped it; I do not believe it made a difference
• Despite this book being pretty new, the names for a bunch of things are somewhat different than the book records them to be

Getting to Know ArcGIS Chapter 2

Notes:

• ArcPro and ArcOnline communicate with each other much better than ArcMap and ArcOnline as ArcPro allows you to sign in
• ArcPro projects can contain multiple maps, geodatabases, folder connections, layer files, task lists, models, toolboxes, and more
• The world symbol next to the “Explore” tool is the full extent button
• The feature layer ribbon is activated any time a layer in the contents sidebar is selected
• Extrusion is the process of stretching flat 2D features vertically so they appear 3D
• To package a map there must be a description in the map’s metadata

Exercise Questions and Screenshots:

• (Modify map contents 5) PM concentrations are highest in Africa
• (Examine the contextual ribbon 2) If you close the content pane, go to “View” and click “Contents.” The Geoprocessing tool is next to the “Contents” button
• (Examine feature attributes 4) Shanghai, China has the largest population
• (Create a 3D scene) The height of the tallest building is 339.76

Getting to Know ArcGIS Chapter 3

Notes and Comments:

• Definition queries make certain features or areas invisible but they do not get rid of them
• To subset from a data set you can use a definition query, the clip feature, or the select and export feature
• Joining the join table to the attribute table requires that the attribute type is the same (e.g. text joins to text)
• You cannot have spaces or more than 10 characters in the field heading in the attribute table
• Spatial join allows you to join data based on location. You combine the target and the join layer into a new output layer
• I can follow along easy enough but if you told me to do this on my own I would be clueless

Questions and Screenshots:

• (Add data to project 5 part 1) The field name that indicates which state the county is in is STATE_NAME
• (Add data to project 5 part 2) The number of Wayne county residents between ages 22-29 is 10,575
• (Join data tables 3) Six years of data are represented
• (Overlay additional data 1) No, I do not see a clear correlation between income and 2010 obesity rates. While many counties with high obesity rates have lower incomes a moderate number of counties with moderate to high incomes also have high obesity rates
• (Examine infographics 3) 18.7% of households had an income of less than $15,000 per year
• (Relate tables 7) There are 4 food deserts in Knox County
• I had a problem displaying the proper amount of LILATracts so I skipped the labeling part

   

Getting to Know ArcGIS Chapter 4

Notes:

• Shapefiles store the data for one set of features
• Geodatabases have the ability to store multiple datasets
• Geodatabases are an ideal model for sharing data as shapefiles are much larger
• Geodatabases have the ability to create an attribute domain which minimizes the potential for data entry mistakes by setting a range to which attributes in each field must be limited to
• In the geoprocessing pane built-in tools are denoted with the hammer icon and script tools are denoted with the scroll icon
• ArcGIS applies a projected coordinate system of the first layer to all added subsequent layers
• Snapping allows you to connect features, without impossibly precise sketching

Questions and Screenshots:

• (Configure snapping options 8) The selected line has 4 vertices
• (Split polygons 12) The Shape_Area value decreased

Getting to Know ArcGIS Chapter 5

Notes:

• Tasks can be documented series of instructions that incorporate or call forth certain tools and commands
• ModelBuilder is a geoprocessing environment that allows you to easily link one tool to another and run one set of operation after another
• In the “Tasks” pane you can follow or define a workflow

Questions and Screenshots:

• (Set up a project 4) The conflict events recorded in the dataset are battle (government regains territory), battle (no change of territory), battle (non-state actor overtakes territory), headquarters or base established, non-violent transfer of territory, remote violence, riots/protests, strategic development, and violence against civilians
• (Author a task 12) 14,211 fatalities resulted from violent conflicts against South Sudanese civilians between 2010 and 2018 
• (Fill out the tool parameters 5) 71 fatalities resulted from violent conflicts against Rwandan civilians between 2010 and 2018 
• (Convert a model to a geoprocessing tool) 41 riots/protests occurred in Rwanda between 2010 and 2018 and 12 fatalities resulted from these events
• (Use a custom script tool 1) The geoprocessing tools of “Select Layer by Attribute” and “Summary Statistics” are combined in the script
• (Use a custom script tool 6) 26,323 fatalities resulted from violent conflicts against Nigerian civilians between 2010 and 2018
