Geography 291: Geospatial Analysis with Desktop GIS

Chapter 9

9.1    I was ready to get started on a clean slate for part 3 so I’m glad this section was straightforward and simple. It was cool that when the buffers overlapped they just joined together. 

9.2    Creating multiple ring buffers was cool and I could see myself using it in a project in the future. Using the spatial join tool to see how many youths had good vs. excellent access was also very cool. Doing it with 3 rings was cool too.     

9.3     This section was a bit more tedious but it was good. It was cool to create the scatterplot.

9.4    I had no problems with this section. The lines looked really cool. It is interesting how many ways you can interpret one data set.

 

9.5    I liked doing the “Your Turn” part of this tutorial. I wasn’t sure if I knew how to do it but I figured it out as I went on.

  

Chapter 10

10.1     Changing the transparency of the land use map so that we could see the hillshade with it at the same time was so cool and I definitely see myself using this in the future.

10.2      This section was super easy. There was one part where I got confused: the book said to “run the tool” after symbolizing a layer. That was weird but I just ignored it.

10.3     I had quite a few issues with this section. When I was using the raster calculator, and I clicked on the raster names to add them to the calculation, they wouldn’t fill in so I had to write everything out. I also messed it up the first time so I had to do this a lot and it was very tedious. I also suspect something else went wrong because my poverty image did not look the same as the books. 

Chapter 11

11.1     This part was so cool!!! I feel like it might take a minute to get used to navigating with the keyboard but I feel like I’m already getting it! So fun! Picture from Denver.

11.2    This was another good section. I liked that we took out everything but the AOI. It would get kind of overwhelming with the whole world map. 

11.3   This section was so fun! The trees are so cute.

11.4    I didn’t really have any issues with this section, I’m just not sure I fully understand it. I know that a lot of the work done was to create the building heights, but I didn’t fully understand the process to get there. Creating the line of sight was so cool.

11.5   This tutorial was cool. Extruding the buildings was very simple.

.     

 

11.6    This section felt like google maps because of all the buildings on smithfield street.

11.7     Creating the video was so cool… I didn’t even know you could do that on ArcGISPro.

Chapter 9

• 9.1: Very short and straightforward, just learning to use the cluster tool
• 9.2: Again very straightforward, didn’t have any issue with the spatial overlay.
• 9.3: This one definitely took a while, at least longer than the others and was definitely more complicated. Did not have any technical issues that other classmates seemed to have experienced though.
• 9.4: At the very end of analyzing for the optimal situation, using the summarize tool didn’t seem to work. Or at least, no change occurred that I noticed.
• 9.5: Another straightforward section that just focused on changing symbols and labels.

Chapter 10

• 10.1: Very interesting to see the 3D landscape overlaid on the 2D map beneath.
• 10.2: Heat maps are among my favorite types of map… that sounds weird to say now that I think about it, but there is something about them that is inherently interesting so it’s fun to play around with.
• 10.3: Was ultimately very disappointed in the end result with this part. Took me two hours to find and put everything together from the model to the codes, and on the last step to run the tool I was met with some unknown error so it felt like a waste of time.

Chapter 11

• 11.1: Basically Google Earth but playing with exaggerated features and time based lighting.
• 11.2: I mean I suppose it’s interesting to see the different layers in different colors contrasting. All came together at the end seeing the landscape reflected accurately.
• 11.3: Shows how to add realistic objects to a map using z features and points.
• 11.4: The drawing of the bridge arch using z points didn’t work, and neither did the line of sight analysis
• 11.5: Very straightforward. Interesting to play around with the height of objects.
• 11.6: Was initially concerned since nothing was happening, then the building finally showed after playing with the properties in a different step. Interesting to see a realistic-ish building model.
• 11.7: I don’t think animation has ever been easier… I joke but its still cool to see an animation which is something like a 3D tour

Chapter 9- This chapter went fairly quickly and I did not run into any problems during these tutorials. Overall, this chapter went more in-depth on using buffers to analyze proximity and to find what’s near something. I don’t think we’ve had to use the buffers yet (unless I’m forgetting an earlier tutorial), but I really enjoyed learning how to use them and discovering more about how to analyze what is around certain places and how you can utilize ArcGIS tools to find useful things about the data. Looking ahead to the final exam, I think this chapter will come in handy, as using buffers is one of the options for the final. In the first few tutorials, I learned how to use buffers to calculate the total number of kids near public swimming pools. I think this would be a very useful tool for businesses to ensure that they are in the optimal location for their target demographics. You can also use the buffers to set location parameters as being excellent, good, or poor in proximity to a certain location- which could influence certain policies and encourage new builds. This chapter also went over some more Python concepts, how to create scatterplots to discover linear relationships, and how to use the Multivariate Clustering tool to analyze and interpret cluster data. The chapter used those last few concepts with regard to serious crimes, but I think that this kind of analysis could be used for various other reasons.

Chapter 10- This chapter was all about rasters, and it was fairly short and straightforward. This was the first time we’ve had to really use a raster dataset, so we started out by importing it and setting parameters for the raster analysis. The first tutorial showed us how to create a hillshade map to show elevation, and how you can symbolize it to better display elevation or land use. It also showed us another way to display elevation, which is to create elevation contours. I think one thing I am beginning to understand about ArcGIS is that there are many different methods to display the same thing, but it all depends on what you want to portray and how you want people to see it. The second tutorial was all about using the Kernel Density tool to make a density map, and then how to symbolize this in a way that makes the trends easy to visualize. Finally, the end of this chapter went into creating a model using the ModelBuilder feature. This section was a little challenging, but the book explained the process very well and I was able to get my model to run. This tutorial also incorporated some more coding, which I think added another layer of difficulty to it. 

 

 

 

 

Chapter 11- The final chapter in the book was pretty short and incorporated things we haven’t learned about yet, but I actually really enjoyed some of the things this chapter covered. The first tutorial showed us how to navigate through a 3D scene. Then, the tutorial went over triangulated irregular networks (TINs). The book explained that TINs are very useful in some high-precision applications like engineering, which require lots of calculations. The third tutorial goes over to how make trees using z-enabled features, and I really liked this part. I didn’t realize that creating 3D features like this was an option, and how many options ArcGIS PRO has when it comes to symbolizing the features. The tutorial had us pick a certain kind of tree species, but there were so many options to choose from. Then the chapter went into LAS Datasets, which was a little confusing, but I was able to get it all done. I was mostly just confused about why you would need to visualize the data like this, but I’m sure there are some very specific applications where this would be beneficial. The fifth tutorial went over more 3D features and had us create floors for buildings so you can view them in 3D using a range slider. Then, we had to create 3D buildings by increasing the Z height of a 2D feature. I did have a little trouble with tutorial 6, and my building wasn’t nearly as tall as the pictures in the book, but I was still able to symbolize the building correctly (it was just very short!). Finally, the last tutorial covered how to make an animation, and I got to make a little movie that moved through 3D frames!

Chapter 9

First two sections went really well and they seemed very straightforward. I had a hard time finding the “Travel Settings group” in 9-3. I searched for it in the search bar and looked around and couldn’t find it. The picture in the book looked really cool so I was disappointed I couldn’t find it. The rest of the chapter was simple and I was able to finish it with no problems

Chapter 10

This was the longest section for me. I really had to muscle through the first two sections. When I got to the third I couldn’t get the ModelBuilder to work for me. I tried to skip that section but after that I think I was flustered and I just couldn’t figure out any of the other sections. I might revisit this one next week if I am stuck on the final and want to take a brain break.

Chapter 11

This one introduced 3D modeling which was very exciting. I didn’t run into any issues in this section. I had a hard time finding some of the panes because the tutorial assumed that I already knew. I wish I had taken notes or remembered where the different sections were. I had to use the search function a lot and sometimes that made it very clunky. Overall it was not too bad and I feel like I learned a lot in this chapter and through the whole book

Chapter 9

 

Chapter 9 was pretty simple and straightforward as it focused on spatial analysis and combining and interrupting data based on different locations. I ran into some issues finding some of the newer functions it asked me to use but I eventually was able to find them and continue on with the chapter.

 

Chapter 10

 

 For 10-1 I did not have the LandUse_Pgh file in my Chapter10.gdb so I couldn’t finish this tutorial. I am not sure why I am missing some of the downloaded data. This has been happening throughout these tutorials. 10-2 was straightforward and I was able to get through it pretty easy but 10-3 was difficult for me when I got to the point when you have to enter some expressions in the raster calculator and that did not work for me. I think I did a step wrong before that but I don’t know how to fix it. 

 

Chapter 11

 

This chapter focused on all things 3D in ArcGIS. I had some issues just because of the nature of the use of 3D but nothing too crazy. It is very cool to see things from this point of view, especially while using the program in exclusively 2D the past 3 weeks. 3D GIS is a bit daunting but these tutorials made it much simpler and easier to navigate and understand. 

Chapter 9

In this chapter, four spatial analytical methods were covered including buffers, service areas, facility location models, and clustering. The tutorials helped me understand how to use buffers for proximity analysis by running the pairwise buffer tool and multiple ring buffers. I was able to create service areas of facilities for calibrating a gravity model and locate facilities using ArcGIS Network Analyst. This chapter also taught me how to perform cluster analysis to explore multidimensional data.

Chapter 10

The tutorials had users process raster datasets to extract and symbolize maps and create hillshade maps. I learned how to make a kernel density map, or a heat map, as well as how to build a raster-based risk index model. It also required me to build a model for automatically creating risk indices. Throughout this chapter, I learned a lot about raster layers compared to vector features which we had been using previously. I found it useful when it taught me how to transform vector feature classes into raster datasets that could be visualized.

Chapter 11

In this chapter I found it useful that the tutorial had us explore global scenes and taught me how to design, visualize communicate, and analyze them. The tutorials also had me create local scenes, TIN surfaces, and z_enabled features from this I learned the difference between global and local scenes. It allowed me to create 3D buildings from the lidar data so that I could work with the 3D features. I also used procedural rules and multipatch models but the parts I found most interesting, useful, and fun were creating the trees and the animation.

9.1- Made first buffer easily. Done. 

9.2- Liked this one because I compared 9.1 and 9.2 together. 

9.3- Got to step 6 but couldn’t complete the tutorial because I couldn’t find the travel settings group button. I looked it up on google and the search bar on GIS. 

9.4- I got all the little green dots on the screen. (INCOMPLETE)

9.5- I liked changing the names and colors of the dots. I was able to do this one. 

 

10.1- Done. Saw the map shift colors and got different dimensions. 

10.2- Tried. Got done with the first part then couldn’t find the correct layer to symbolize. I tried every layer but couldn’t find one layer with all of the correct things to put in.

10.3- I tried entering the code into the raster calculator and double checked it but it didn’t work. I just entered the names and numbers, but it didn’t really work for the rest of the tutorial. So I just moved on to chapter 11. 

 

11.1- I liked playing with the different keys and changing the layout of the map. 

11.2- Followed the book but some of my map was cut off. Probably a small mistake I made. But I was able to finish this tutorial. 

11.3- Favorite tutorial yet. Made the trees. 

11.4- The first part of this looked cool with the little dots making up the buildings. I also liked creating the bridge. 

11.5- Done. Interesting to see the different layers in both buildings. 

11.6- Struggled a little bit but finished. I liked looking at the street view. 

11.7- Making the short animation was really cool because you got a mini tour of the city. 

 

Chapter 9

9.1: This was just using the clustering tool, very easy.

9.2: The first half of the tutorial was very straightforward and easy but when using the spatial tool I was having trouble using the output field.

9.3: I had the same issues as 9.2, the spatial tool was hard to navigate, I am not sure if updating the software will fix it or not.

9.4: This part was very similar to the rest of the chapter with just changing the map to be able to read it better.

9.5: This part was very straight forward, just changing the symbols names and indicators.

Chapter 10

10.1: This was the longest tutorial of the chapter but it was very easy to follow after the first part which I had difficulty with. This section does involve a few new tools.

10.2: This tutorial was very easy, just introducing new tools to get familiar with. I am not super familiar with the singular tool or clustering tool yet but these sections have definitely helped.

10.3: This section proved to be very long and gave me some difficulty with the coding. I could not figure out how to connect the raster calculator to everything else.

Chapter 11

11.1: This tutorial introduced the 3d view for the map, was very short and easy to follow. 

11.2: This tutorial is very easy to follow. It is very similar to 11.1. 

11.3: The use of the 3d features are very cool. The section was again very similar to the last two. 

11.4: This section was cool building things but my outcome did not look like the books so I am sure something went wrong.

11.5: The slider tool on this tutorial was very interesting, this was a very interesting tutorial to use. 

11.6: The street 3d view was very interesting and I enjoyed doing it.

11.7: This section tied the chapter together, it was definitely hard at first but I learned a lot. 

 

9-1 : I was able to follow this tutorial perfectly fine, but I’m not really sure what it means.

9-2: Same as the previous tutorial.

9-3: I got a couple error messages when I tried right click UseRate and clicked Calculate Field. I’m assuming it’s because I typed in the expression wrong, maybe I put spaces when I shouldn’t have. I believe this inhibited me from making a scatterplot, as when I typed in the X and Y axis fields, there was no button to apply or even in the Edit tab i wasn’t able to save. So I was unable to completely finish the project.

9-4: I thought this tutorial was really interesting. The lines connecting pools and demand points are a fun way of visualizing on a map.

9-5: I liked the background of this tutorial. Mapping crimes, especially violent ones, are really important and its cool to see in real time how you can define the data to make it more understandable.

10-1: I don’t have “LandUse_Pgh” in my files, only “LandUse_Pgh.tif”. So, I have the land use for a good distance around pittsburgh instead of just the city itself. Actually, another time I tried to find it in the geoprocessing pane it was there. Sometimes files just don’t show up for me. I also don’t have NED_Pittsburgh, just NED. In the end, my tutorial looks just like the one from the book, except the Pittsburgh outline disappeared somewhere along the way and everything I did to the map didn’t just go inside the Pittsburgh limits.

10-2: I thought that this tutorial was interesting. Learning how to make a heat map seems pretty cool.

10-3: This tutorial was really long for me. I was able to do it all though, except for the fact that the poverty index model goes outside the Pittsburgh borders. Not sure why that happens to me so much. This was really complicated but seems useful.

11-1: It was fun playing around on this tutorial. The exploration was interesting.

11-2: Similar to the last tutorial.

11-3: I don’t see the “Get Z From View” button. I also don’t have the cute trees the book has but it is a fun tool to know.

11-4: This tutorial was also interesting to do. Creating the buildings out of thin air was cool. I definitely messed up somewhere along the way though because I didn’t get the proper sightline at the end.

11-5: Not too sure how many uses these tools have, other than scale I guess.

11-6:  This tutorial was super fun. The end product, the Smithfield street 3D, was cool to explore and the little planters, trash cans, and fire hydrants were cute.

11-7:Ok this one was cool. This chapter in general showed a lot of little things to make the viewing and creating experience more fun. It is taking a very long time to export the movie though which is a little annoying since it is only a draft and not that long in length.

9.1 – I thought we had learned how to use the buffer tool before, maybe I just remember reading about it or just seeing it in a different chapter’s tutorial. 

9.2 – I think this section is really cool. It’s really helpful to be able to select within a buffer to help narrow down data more. 

• I don’t think i was able to do the section section of this tutorial properly, I was not able to find the output fields or merge rule part of the spatial join tool, I did my best to find what seemed equivalent but it does not look right 

9.3 – My Polygons_Tags_Pop attribute able did not have a name section, so I did what I could following it but my stuff is a little wanky. 

9.4 – This section was the easiest to do because the book actually was following along nicely with the software. I also think it is cool that we can locate facilities so easily.

9.5 –  I think knowing how to analyze and use clusters will be very helpful in the future of my GIS career.

10.1 – I really enjoyed this section, it’s cool to be able to create stereotypical features I used to think of when I thought about mapping. 

10.2 – When I ran my symbology pane for heart attack density it didn’t stay within the area and went to the whole map and I am not sure why.

10.3 – I was not able to get multiple parts of this section to work, and the sections followed off of each other so I was not able to complete the entire section. 

• My FHHChildren field was not able to be made correctly
• I could not calculate ZFHHCHld = (!FHHChildren! – 45.2) / 66.8 because it said FHHChildren did not exist 
• the kernel density tool would not drag into multiple areas on my screen, and because of that I was not able to complete the rest of this section

11.1 – This section was fun to play around with, 3d renditions are really cool and I’m excited to work with them now 

11.2 – I don’t really understand the difference between local view and global view. 

• I followed the directions for the symbology and it didn’t look the same

11.3 – I think the trees are cute and I will like putting 3d objects in later projects

11.4 – This section was challenging in a good way, it was rewarding to see my buildings pop up. 

11.5 – Using scale is more simple than I thought it would be.

11.6 – Creating the building was interesting, but I feel like turning on a street layer just to see planters was sort of pointless. 

11.7 – This section was the most interesting from the book – I had no clue GIS could be used for things like this.
