This week, without any reading and most likely the same as many of you did, I downloaded and prepared for the GOEG 291 final scheduled to be due next Friday. For this, I downloaded the necessary data from the Delaware County GIS Data Hub: the Parcels data, Street Centerline data, and the Hydrology data. I then organized this into a file labeled “Delaware GIS Data” on my laptop, extracted each dataset from its original zip file, and converted it to the necessary shapefile format. This created a new file folder for each data set that contained the usable data files. Once the files were in a usable format, I then created a new ArcGIS Pro map project and inserted the three dataset files. To do this, I selected the “Map” tab, then the “Add Data” selection under the “Layer” portion. This added each dataset as a layer on the “Contents” tab. Finally, I recolored the imported data layers (as they were all inserted as the same default pink color) to make each layer visible. As for the final project selections, I plan on doing the “selecting and classifying land uses”, “making new shape files from existing shape files”, and “mapping change” choices.

Cherry Blog week 5 

Chapter 4 

So far, which is quite honestly to be expected, is that the instructions and process of what we’re doing in GIS are getting progressively more complicated. I really struggled with the beginning of the chapter, where we were working with a lot of export files. I’d realized when I got past that part of the assignment, and I was unable to do something a few steps later, that I had done that completely wrong and had to essentially restart my project. 

This chapter altogether was a bit of a problem for me; I did learn quite a few new things regarding attribute tables and quite a few other things. I also liked seeing the crime data for 4-3 just because it looked interesting on the map. 

(My computer is broken, so I can’t access the screenshots from this section.) 

Chapter 5 

So far, the steps for Chapter 5 have been pretty easy, especially in comparison to Chapter 4. Besides doing different things with properties, there seems to be a lot of stuff that we have done previously, such as adding data or symbology stuff. 

Once I got to 5-5, where we were using Excel sheets, I was really confused, considering I’ve never worked with Excel sheets prior to this assignment, so it took me a lot longer than anticipated to do that section of the assignment. Although I was actually able to successfully import the information from the Excel sheet without too much trouble, that felt like a lot of accomplishment. I also feel like Excel is definitely something I will have to use in the future, so I am glad to get a little bit of experience using it. 

It was also interesting learning about what a Choropleth map is in more detail. I know we have worked with them quite a lot, but it was interesting to learn how we can join data alone to create one. 

 

 

Chapter 6 geoprocessing 

For this chapter and especially the 6-1 section, I actually quite liked learning how to work with the pairwise dissolve tool. It was kind of interesting to see the process and see the sectioning of the units turn into neighborhoods. Also, far through this chapter, I feel like I’m working on and going through the process of quite a few different new things, or at least things that weren’t significant enough previously to remember doing. Although getting to the end of 6-2, where I was trying to do your turn section. The selection by location was easy, but I keep getting confused on how to properly export some features, so I was struggling to save the selection under a different name. Overall, this chapter was quite a lot easier than the last two, so I was able to move smoothly through the post of the chapter with only a few hiccups, which is one of the first chapters I have been able to do so with so far with GIS.
