GIS 5007 - Computer Cartography: Module 5: Choropleth and Proportional Symbol Mapping

-

This weeks module topic covers choropleth and proportional symbol mapping. A choropleth map displays normalized data as shaded points, lines or areas. 

Students were asked to create a choropleth map showing the overall population densities in European countries and then tie in the amount of wine consumption and overlay using proportional or graduated symbols.



A few steps I used to create my map were: 

  • I chose to use the yellow-red-brown (continuous) color scheme. I chose this scheme because it is friendly to the color visually impaired person for easy determination.
  • With the freedom to choose the data classification of our choice, I chose the Natural Breaks method for population density, and graduated symbols for the amount of wine consumption.
  • Selected a symbol of my choice for graduated symbols layer as a .SVG file. 
  • Use an inset map to clarify congested map areas that are tough to determine.

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...

GIS 5100: M4 Lab: Coastal Flooding

-

For this week in Module 4 we take a look at coastal flooding and erosion for Mantoloking, New Jersey and Collier, Florida.  For Mantoloking, New Jersey we take a look at elevation changes post Hurricane Sandy. Using DEM and LiDAR we compare pre and post storm data to evaluate where and how much erosion has occurred along this New Jersey shoreline.  After moving on from the section above, this assignment was by far the toughest GIS assignment yet in the GIS journey. There were many tools and trick I have not yet worked with or had experience with making this a challenging assignment. I tried my best to accomplish this assignment but with my new GIS background I unfortunately cannot fully explain what our end goal should have been. What I can explain is we should have seen flooding areas and destroyed building through DEMs and LiDAR data.

GIS 5007 - Computer Cartography: Module 6: Isarithmic Mapping

-

In this week's lesson we covered topics about flow maps, and isarithmic mapping. To show our understanding and expertise of this topic we are to create a map depicted with continuous tones, hypsometric tints, hill shade effect(s), and contours. Students are with data to create an isarithmic map of precipitation data for Washington State during the time frame of 1981 - 2010. The data used for this project was prepared using the PRISM interpolation method  from the PRISM Group at Oregon State University.  First, I created a map using continuous tones to show the average rainfall data, without contours and hillshade effect. We can see the smooth, continuous flow of change for the data. Continuous Tones Next, I used the same data to create a hypsometric map, with the hillshade effect, to display the same average precipitation data. This map shows more clear, defining changes in data verses the continuous tones map. Hypsometric Tints Last, I added a contour layer on top of my ...
