ArcGIS:

Here’s my final map with all three instructed layers along with a scale bar, legend, north arrow, and title. Unfortunately, my screenshot is horrible quality. Also, I had to unzip all of the files to be able to drag them into ArcGIS.

 

P.S. Thanks, other logan for the idea of creating a whole layout rather than just a screenshot with the visible layers.

 

Chapter 5: went smooth for the most part. Making the ModelBuilder ribbon was cool. I think I did the Python coding correctly.  

In chapter 6 I ran into an issue with publishing features and preparing the map for collection. My content did not have the TreeInventory feature layer. 

Chapter 7: I made some mistakes in the Geocoding process. I could not add the files to the map. I think there was also some confusion with me and labeling that I had messed up in the last section. 

Chapter 8: Was a cool way to make 3D maps. However, I think I made some errors while browsing and couldn’t find the correct file. I’m not sure which chapter but I did have an issue with an error coming back after running a tool. It said the function couldn’t be performed because it was already added. 

 

 

Chapter 10: I had a slight issue but just skipped the steps and moved on. In exercise 10b step 10 it wanted us to go to the position tab however there was no placement drop down or in the next step there was no stack drop down. Also in exercise 10c I could not figure out how to insert the Max Advertised Broadband speed map frame into the layout tab. It kept making another separate tab. 

Week five work went smoother than week four but there were still some chapters I just couldn’t really get to do what they were supposed to. Over all though I feel like I was more comfortable with the software this time around so I felt a lot better about the exercises that went well. I felt like I could navigate everything pretty easily and even though there were still some funky hiccups I think I understand things better now.

Towards the beginning of the week four work, I didn’t have technical things figured out yet so I was unable to get very far with a few of the exercises but I figured some things out and it went a lot smother in the later chapters of this week.  

These ones went well

These ones did not

These chapters were fairly self explanatory, I only got stuck a few times but was able to skip and navigate the rest of the chapters easily. My problem is that I am inpatient and I don’t like to read everything on the screen so I miss things. The most interesting thing in these chapters for me was doing the South Sudan coding. I think it was cool to input South Suden is equal to the years or whatever the directions said. It was cool that the map and software could do that. Again, I took definitions because some of the words in the chapters were hard to understand without knowing the definitions. 

Defintions:

Task: [software] A set of preconfigured steps that guide users through a sequential workflow in ArcGIS software. 

Definition query:[ESRI software] In ArcMap, a request that examines feature or tabular attributes based on user-selected criteria and displays only those features or records that satisfy the criteria.

Query expression: [programming] A type of expression that evaluates to a Boolean (true or false) value, that is typically used to select those rows in a table in which the expression evaluates to true.

ModelBuilder:[ESRI software] The interface used to build and edit geoprocessing models in ArcGIS.

Adress Locator: [geocoding] A dataset in ArcGIS software that stores the address attributes, associated indexes, and rules that define the process for translating nonspatial descriptions of places, such as street addresses, into spatial data that can be displayed as features on a map.

Overlay: [analysis/geoprocessing] A spatial operation in which two or more maps or layers registered to a common coordinate system are superimposed, either digitally or on a transparent material, for the purpose of showing the relationships between features that occupy the same geographic space.

Buffer:[spatial analysis] A specified zone around a map feature or features, measured in units of distance or time. 

Dissolve: [ESRI software] A geoprocessing command that removes boundaries between adjacent polygons that have the same value for a specified attribute.

ArcGIS Pro Portion:

I have absolutely no idea why but when I save my map exports as PDFs it has the .pdf tab but it saves as a Chrome HTML?? When I open it it takes me to the PDF but why is it online? Here’s my map though (I should have probably made the map more zoomed in):

Weird PDF link: DelawareCountyMap

Chapter 5:

This chapter was a lot easier now that I know the basics of the software from last week’s chapters.

A)

B)

C)

I did the entire chapter without many issues, but when I tried to package it, I got an error message that my map has no layers.  Not sure what to do about this because my map definitely has some layers.

Chapter 6:

A)

Not much to show for this section, but I’m starting to get more confident using the software. We’ll see how long that lasts!

B)

C)

I can’t seem to find the ArcGIS Collector app anywhere on the IOS app store.

Chapter 7:

A)

B)

I am doing all of the steps correctly, but to be honest I’m not confident I know exactly what I’m doing.

C)

Chapter 8:

A)

Not sure how to access the appearance tab to change transparency. (Update: I figured it out)

b)

C)

D)

Made a cool animation of changing robbery demographics, unfortunately this is only a screenshot. Sorry!

Chapter 10:

A)

B)

Messed around with labeling libraries in Salt Lake City!

C/D)

My final layout below!

Note: Downloaded three assigned .shp filed from Delaware GIS Data Hub.

 

Chapter 5

first step in tasks, I want to break down what I did. County is equal to South Sudan (only select South Sudan) and Year is >/= to 2011 (South Sudan data from 2011+). This task thing was very strange I’ve never used it before.

It was interesting learning tasks but I don’t think the text explained what this step was adding very well.

I prefer the model builder to the task route visually but the modelbuilder lacks the instructions given when using tasks so its a give and take. Here’s me running my model:

I haven’t started it just yet but I am scared to run Python code. I don’t want to run it I’d rather use the tasktool or modelbuilder >:(

When I tried to package my project I got a “conflict” saying that a geoprocessing item failed and it couldn’t package it. This was weird because I didn’t have any failed codes, but I fixed it by removing items with errors. I wasn’t feeling very extra so I skipped the “on your own” here where I check to see if this uploaded to my online account.

Chapter 6

Here is my created symbols for the trees:

It wouldn’t let me name the project “TreeInventory” for ArcOnline (it says the name is taken) so I added my name to the end “TreeInventoryFraire”.

My map for ArcOnlinne so far:

For the app thing, there is no app called “ArcGIS Collector” so I downloaded the first one that popped up called “ArcGIS Field Maps and it took  forever.

Well I downloaded it and then it said that I don’t have permission to use the app so I had to skip this part.

Attempt one at editing the new features attributes:

I got through his exercise but it was weird. I had to keep reopening my project because the program was losing its location and said it didn’t exist. I think this screwed with the portal linking to my online account because after refreshing and readding the layer it said that it couldn’t find it either. I think it might be because I had to give the online layer a different name since the map name was “already in use”.

Regardless, I now know multiple ways to edit maps from many devices!

Chapter 7

Starting off strong with more so actions like “join these two layers” instead of a step by step. Getting harder! Let me know I need to pay attention to what I’m doing more.

When I tried to save the locator it originally said that a parameter was missing. I think it was because I put “Houston_” and not “Houston_Locator”. File names are important (And annoying).

I don’t really understand what rematching did. I read the text and it’s still a little confusing. I have actually little to no idea what this did. Did it just match addresses that are the same but weren’t classified as the same?

My map after doing the merge, dissolve, and selected specific properties within the buffer:

When I opened the attribute table after the spatial join I only saw one row of data…I chose the wrong input for my spatial join! went back and fixed that annnndd it still looks the same D: Looking at the attributes of the buffer, it only shows one row of data as well.. I’m not really sure why this happened. My clipped layer and the following selection layer look fine in the attributes. Tried for a third time and it worked! I think I was selecting the wrong inputs, pay attention Logan.

Our pop-up menus look very different than the book.

My final map of this exercise with some selected prospective property locations, proposed/existing bike paths, and bike stations:

Chapter 8

My first map of robberies in January, how exciting:

I didn’t really consider the applications of GIS with crime. It obviously makes sense but it just adds another use of GIS for me.

Every time it says “run the tool” it reminds me of the artist group Run the Jewels 

negative points for bringing in the empirical rule and z-scores. Stats = no.

I hate this:

real vomit from all these cubes. It feels like the matrix:

I don’t want to work documenting crime spots, that’s for sure.

I did 8c and got the mods done. I just noticed that there is no topography for this scene. Not really a problem because I can work but odd:

Range and time on crime son (it’s playing in the picture so it looks a little empty right now):

Chapter 9

I started by extracting masks and mosaicing layers to make this property boundary:

Running the aspect tool and seeing the colors brings back trauma from remote sensing. I know these colors all correlate to the cardinal direction of the slope.

When adding the outline to the planting sites I made it purple instead of black because it was hard to see on the hillshade that was already greyscale and the slope added green/red. I promptly changed it back after adding the slope.

Here is my map with the property boundary, vineyard blocks, and planting sites. I also have on the 3pm hillshade shadow. There is limited area for planting on this property:

This modelbuilding reclassification probably won’t work. I don’t have a start and end column, only value and new.

My finished maps after raster calculator (which was being a little stinker). The dark red shows the most favorable planting sites within the black outline:

Chapter 10

My first map for 10a:

I didn’t have a symbol selection in my label ribbon. I had to right-click the layer and select labeling properties to get to the symbol tab it asked of me.

My created labeled map of Utah:

My finished layout of broadband speed/libraries in Utah County. (I have no idea why it made the pdf a html link? This has never happened to me before. I included a screenshot of the map because the link doesn’t even work.)

Layout1

 

In ArcGIS pro we will be completing projects that have maps, layouts, layers, tables, tasks, tools, and connect to servers, databases, folders, and different styles. ArcGIS Online is public content that if connected to an organization you can share projects and information. Geoprocessing tools will perform spatial analysis and manage GIS data. Cluster → aggregating. 

I ran into an issue that there was not a purple school symbol so I substituted a blue school symbol. There must’ve been an update with symbols. The ToBreak attribute helps to show how many minutes walking a distance is. I got stuck on chapter 1, step 9 “Under Try a drawing style, select Types (unique symbols). I could not find “Try a drawing style”. I ended up stopping for the day and came back and found it. After just starting exercise 2B I ran into a labeling issue. The appearance tab is now labeled as “feature layer”. It was cool to transform my map into a 3D form and use the explore tool to navigate around. When trying to export their selection to a new dataset I ran into issues at #3 in the Geoprocessing pane. All of exercise B was messed up and I had questions about a step that was very important because it carried over into exercise 3B. Stopped at page 91 on Import layer symbology. I ended up completing chapter 4 but could not save any progress because of a computer issue.
