Module 9- Flowline Mapping

-
This week we focused on Flowline Mapping. Using a base map from ESRI created in ArcMap, we were required to only use Adobe Illustrator to create a distributive flow map showing immigration to the U.S. Two data sets are displayed here: the number of immigrants per continent in 2007 and a choropleth map of the U.S. displaying the percentage of immigrants for each state. The first data set uses flow lines of proportional width calculated using the number of immigrants. This immigration data was derived form the 2007 Yearbook of Immigration Statistics created by the U.S. Department of Homeland Security's Office of Immigration Statistics.

I chose to work with FlowBaseMapB, which meant moving some continents right away. After relocating to have North America in the middle, because this map is about immigration to the U.S.. I modified colors for all continents and added a drop shadow effect. I also stylized the background with a flat grain effect so it wouldn’t be plain yet still allow for text to read clearly. After calculating each flow line’s proportions and testing colors and effects, I chose to keep them black. These lines are the main focus of this map and black stood out most against the colors already in place. North America is noticeably lighter in color to visually stand out against the dark tones used for other continents. The title deserves some attention here too since it specifies the year the data reflects, so I used a dark red tone in an attempt to immediately bring attention to it.

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

GIS5100 Week10: Final Project

-
Image
My final project was dedicated to finding suitable areas for a new Elementary School site in Riverside County, California. I started out by compiling 5 pieces of key datasets: County Assessor parcel data, California Schools, Fault zones, Roads, and Public sites. First I performed euclidean distance analyses on four of them in order to produce zonal raster for preferred areas. A weighted analysis based on prioritizing safety shows that ideal areas fall within Hemet, Menifee, and Palm Springs Unified School Districts. Final analysis results show how active school sites are distributed, where all vacant parcels of at least 5 Acres or more lie, and recommended areas for a new school site. The two circled were determined to be the most suitable after analyzing results from weighted overlay analyses and locations of parcels. Additional setbacks are anticipated as more conditions are implemented to the list of mandatory criteria needed to finalize parcels. Looking b
