Module 4: Identifying Features using different spectral combinations

 

This week's lab was about utilizing different spectral combinations to identify features. Different combinations can be utilized to help identify very specific features or phenomena. Analysts in the wild use these different combos to help solve problems such as deforestation, flooding, or change detection.

My personal experience is in the military intelligence world, where we utilized these different bands to help us identify or expose dangerous operations. We could use these different combinations to identify changes in equipment location, homemade explosives/IED identification, as well as verifying if a site is operational or not. One example, closely related to this assignment, would be to verify if powerplants were operating. The easiest and quickest way to determine if they were operational would be to look at the stacks/flumes to identify smoke or vapor, or to identify changes in water temperature in the cooling ponds.

Orientation GIS 5007 Blog Post

 Hi! I'm Chris. Please see my story map here ! I am a USAF veteran utilizing the VA VR&E program. I am a graduate student looking to expand on my GIS knowledge. I served as a Geospatial Analyst for 12.5 years and currently hold a B.S. in Geography and B.S. in GIS. This seemed the next logical step to utilize my education benefits.  Upon completion, I hope to utilize my skills to improve my current companies GIS practices.

Module 5: Parsing Data, Creating XY Data, and Geocoding Addresses

      This weeks lab was data intense. We had to find and download data, clean the data, and import it into ArcGIS pro. Using data from the state of Florida and the US census bureau, we were able to identify and locate schools in Manatee county, Florida. Once we had the data, we had to clean it up within excel and parse the data so that each attribute had is own column. When the data was clean, we could add the data into Pro. With the data in the program, we could create a locator and geocode the addresses within the table. Once geocoded, we were able to place the points onto the map.     This labs focus on data manipulation and its importance will play a factor in the coming weeks. We will be utilizing these tools to help us in the final project so we can properly portray our maps.  Link to webmap:  https://pns.maps.arcgis.com/apps/mapviewer/index.html?webmap=81d9894c2bef4f89adab4ec687536c68

 Lab 2 was a success and an absolute wonderful refresher for me. Cartography is probably my favorite thing about GIS. There is something about seeing data displayed on a map that piques my interest. I had some issues during the lab, however, it wasn't from the program or the map creation itself. I found myself rereading the lab instructions multiple times to figure out some of the processes needed for the completion of the lab. Luckily, my peers posted in the help forum to help me fix the issues and understand where I was going wrong. Additionally, I enjoyed learning new and better ways to create certain map elements. I had issues with dynamic text before but for some reason it just clicked in this lab.
