GIS5935 Week 4-- Networks: Network Analysis

-
This week in Special Topics in GIS was our first week looking at Networks, we focused on Network Analysis specifically.

There were two parts to the lab, the first was a set of introductory exercises to help us refresh on how to create a Network using ArcMap's Network Analyst extension tools as well as review the elements that make up a functioning Network.

For the second part of the lab we modified data for provided Network. First I created a new Network Dataset with Turn Restrictions by adding RestrictedTurns and Streets feature classes to the data frame. A point shape file of Facility locations was used for Stops. There were a total of 19 Stops that resulted in a total time of 105.5 Minutes (1.76 hrs).



For the final portion of the lab, I created  a second Network Dataset which included a Traffic Model. The Traffic model is enabled in the Network setup wizard and allows your network to use historic traffic data for an analysis. The map below displays the new route and total travel time (also 105.5 Minutes). 



I've only ever created basic networks to calculate fastest routes in ArcMap. Going through the attributes for feature data sets in more detail became overwhelming at times, but also helped me gain a much better understanding of why all the pieces involved are necessary and how they are utilized.

Module 6- Proportional Bivariate

This last module dealt with proportional bivariate mapping methods. Below is a proportional map reflecting negative and positive values for the increase and decrease in the number of jobs across the U.S. We had to convert the negative values into positive values for this purpose, which allowed to symbolize is proportional to the positive values for comparison. I selected a light bright blue hue to represent the loss of jobs and a warmer purple hue to represent jobs gained. For this particular symbology need, the challenge was not so much the quantity of the values I wanted to communicate. The challenge was finding a balance and gain a better understanding of how to use color themes for that purpose. Initially, I had considered using red and blue (as in hot and cold), but it felt too political and not related to the subject matter. The main exercise for this module demanded that we create a bivariate map displaying the relationship between obesity and physical inactivity perc

Module 4- Color Choropleth

This week's module dealt with Choropleth mapping and color theory. Not being an artist, this was somewhat intense and thought-provoking. Our lab was great in walking you through the process of selecting the right color theme for a map. First, we covered some exercises in color ramp progressions. Below is an example displaying three varying gradients using the same base dark green hue. Original intervals: 51, 26, 31. In the Adjusted Progression, I reduced the previous intervals by -10 and added the values to each new set of RGB values. This appeared to make the hues above a shade darker. The adjusted progression is noticeably a shade darker in hue than both linear progression and ColorBrewer. ColorBrewer is also slightly more green, you can notice this change on the lightest color. I’m unsure what the formula used to produce those hues is, but they exhibit a bit more saturation within the hue. For the main lab exercise, we had to create a map displaying the change in the cou

Module 5- Analytics

Now that we've developed a basic comprehension of color themes, labeling, and typography. This week we dived into creating an infographic using data based on the County Health Rankings data from 2018. This is my very first attempt at an infographic, I don’t think it turned out very well. But I learned a lot overall on how to think more artistically, which is not common. I thought about color themes, placement of data, and amount of information to include and in what format (chart, text, map?). It gave me a lot of ideas on how to tackle the next infographic. Another thing I considered was visual balance by seeing how things looked like when aligned with certain ways and combinations. Given more time and tools on this assignment, I would take advantage of software such as Photoshop to include a fun background that compliments the information supplied via ArcGIS Pro.
