Coy Potts - GIS Professional - Chicago Market
This project page contains a compilation of maps that I created while in my introductory GIS course at Eastern Illinois University. They show a progression of learning with more complicated processes being involved as the semester progressed. These maps are ordered in order of their completion, with the most recent one at the bottom.
Invasive Species: This map analyzes the effect of invasive species on croplands in each county within Illinois
Projection Comparison: This map analyzes the difference that a projection can have on an identical map, and measures the changes between the two
Tanner's 1833 Georeferenced Map: This map analyzes the accuracy of a map of Illinois created by H. S. Tanner in 1833 georeferenced underneath modern day GIS files that outline the state boundaries.
Digitization: This map is a very basic first attempt at learning the various methods of digitization.
Poison Fields and Their Effect on Diabase/Basalt: This map was my first introduction to an Access database, which contained much more information than was needed to complete the assignment. I was tasked wtih querying out the information that I needed and performed mathematical operations to get percentage values that displayed the effect of poison fields on diabase and basalt in the region.
Appalachian Watersheds: This map invovled a few functions that required mr to first narrow the data down to a much smaller area of interest. I clipped a few sets of data to the area and performed a few mathematical operations to see which areas were most affected by mining in the area over the years.
Planer vs. 3D Model: This map compares the difference in two maps of the exact same thing, one being in a planer view, and the other in a 3D view. I also experimented with the exaggeration of the terrain to give the desired effect. Although this is the moraine left by the most recent glaciation over Illinois, the terrain isn't exactly as rugged as the 3D model might insist.
Tornado Coverages: This map shows the county that is most affected and least affected by the effects of tornadoes between the years of 1960 and 2010. I first applied a buffer to each of the tornado swath paths, which were then used to calculate an area of coverage. After I had the overall area of total coverage for each county, I then determined the two that had the most and least amount of tornado coverage.
Via LinkedIn profile recommendation in response to my work as a GIS Tutor and Research Assistant:
"Coy has an excellent understanding of the integration of GIS and relational databases, and is always diligent and professional. He helped clean and organize a very messy GIS-relational database, and discovered and corrected numerous errors during the process that many people would have missed. I highly recommend him."
- Dr. Barry Kronenfeld, Assistant Professor of GIS, Eastern Illinois University.
Via LinkedIn profile recommendation in response to my work as a Teacher's Assistant:
"Coy is dedicated, driven worker. His attention to detail and commitment to quality are exceptional. He is a team player, but has a noteworthy ability to deliver results independently without micromanagement. I highly recommend his abilities and work ethic."
- Dr. David Viertel, Professor of Geography and Geology, Eastern Illinois University.
Via LinkedIn profile recommendation in response to my work as a GIS Intern:
"Coy is very comfortable working with GIS and spatial geodatabases and works diligently to complete projects quickly and efficiently. He is always eager to learn new GIS and graphics techniques and apply them as they are needed. Coy has been a great asset to our mapping program at ISGS and his positive attitude and interactions with others have been enjoyed by the mapping staff. I highly recommend Coy for his GIS skills and dependability as an employee."
