GIS 5007 - Computer Cartography: Module 3 - Cartographic Design in ArcGIS Pro

In this week's lesson we covered topics about Land Partitioning Systems, Cartographic Designs, and Perceptual Organization principles. We learned about historical and current methods for land demarcation and systems used to divide land. Next, we learned about Perceptual Organization, and Cartographic Design using Gestalt's Principles: visual hierarchy, contrast, figure-ground, and visual balance. 

The deliverable(s) of the action plan required by students is to create a map in ArcGIS Pro of Public Schools in Ward 7, Washington D.C. The map we create must display our expertise in Land Partitioning Systems, Perceptual Organization, and all four of Gestalt's Principles. 

Steps for creating my map:

• I used the "clip" tool to create a new layer "Ward7_Schools" on the map for all schools only in Ward7. Before this step there was only a layer for schools found in the entire Washington D.C. area. Once my new layer "Ward7_Schools" was created I chose a relative thematic symbol for my map. I used my knowledge with symbology to denote the differences between elementary, middle and high schools. 

• I established a figure-ground relationship in my map by eliminating any data mapped outside of Ward 7. I was able to achieve this technique by using the “clip” tool on all layers relative to Ward 7. Layers affected by this step were anything related to environmental, transportation, and boundaries.  

• To achieve adequate contrast in my map I followed the tips from our notes. I used relative color options for each layer and kept the color palette relative. For example, each school category is an assorted color. Elementary schools are medium coral light, middle schools are red, and high schools are dark umber. Using this method, the viewer can easily distinguish between the class differences.
