Module 7- Choropleth and Proportional Symbol Mapping

-
For this lab exercise, I created a choropleth map showing the population densities in European countries and wine consumption portrayed by proportional symbols. The majority of the map was completed using ArcMap and Illustrator was used to adjust labeling and finalize the layout.

This week we focused on Choropleth mapping. This meant that we got a deeper look into how distribution data is calculated and becomes different symbol sizes, and how to select a set of color hues. To represent population density, I went with a light- dark orange scheme compiled using ColorBrewer. We’re displaying population density, using this ranged color scheme seemed appropriate to symbolize density of an area whether the reader suffers from color blindness or not. For wine consumption symbology, I chose to go with the Graduated symbols method because the size of the symbols are directly attributed to the values they are representing. The data in question being wine consumption amounts, which is quantitative information. Instead of going with a standard of 5 classes, I chose 3 in order to lower the chance of a reader perceiving circle sizes wrong. This way it’s just small>medium>large circles different enough in size to easily read (hopefully).

GIS5100 Week10: Final Project

-

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

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.

Module 3- Terrain Visualization

In this week's module, we covered various terrain visualization techniques, including contour lines, hillshade manipulation, and the use of digital elevation models (DEM) on a 2-dimensional surface. The main exercise required to overlay a land cover layer of Yellowstone over an elevation raster layer. Seen below is my final result. On the left is land cover, with some transparency, over a traditional hillshade effect. I selected a traditional effect because it best represented land cover features. On the right is the elevation with a multispectral hillshade effect.  I went through a few color ramps to test which best complemented this DEM's physical features. I also went ahead and grouped many of the original land cover features into Pine Trees, Douglas Firs, etc. in order to generalize the different types of tree types. As for the map layout, at first I only had a single map frame and tested ways to represent elevation alongside land cover since I would otherwise have to mak
