 During the first week of the GIS Remote Sensing course, we learned how to qualitatively analyze aerial photography by looking at variances in tone and texture in the first map, and shapesize, pattern, shadows, and associations in the second map. The analyzed maps are depicted below.  Picture 1: Texture and tone reference spots located on an aerial photograph.  Picture 2: Shadow, Shapesize, pattern, and association reference points were found in an aerial photograph for future deeper map analysis. 

 During the last week of Intro to GIS, we learned how to utilize control points on an unreferenced map layer. This provided georeferenced points on the originally unreferenced map layer, placing it correctly on top of baselayers while using RSME as a guide to accuracy. Additionally, we edited map layers to add newer construction elements in the form of buildings and roads that were not previously on the map. Lastly, a LAS dataset was used in a Scene Map to create a 3D map of the main campus location of the University of West Florida. Below are the final maps for each of these steps.  Figure 1: University of West Florida Main Campus Map. Ariel photographs georeferenced for accuracy, and new construction of gym building and Campus Lane edited into the map. A 330 and 660 ft buffer was also created around a protected eagles nest.  Figure 2: 3D map of the Main Campus of the University of West Florida. 

 This week, we learned the beginning steps of data management via geocoding and georeferencing. In the assignment below, we utilized public government data, through the Florida Department of Education and the Census Bureau, to extract school addresses for all school locations in Brevard County, Florida. Cleaning up the free data on excel, we uploaded the information into ArcGIS Pro to create a geodatabase and geocoded all the address points. The resulting map can be seen below.  Figure 1: ArcGIS Map of addresses for elementary, middle, high schools, community colleges, universities, and combination schools in Brevard County Florida.
