Georeferencing

-

 

This map depicts the main campus of the University of West Florida, including buildings, roads, and an eagle nest.

In this project, I learned how to georeference. I was given road and building layers that were already properly georeferenced. Then, I added two aerial photographs and added control points matching the properly projected features with aspects of the photographs. I made an effort to keep my total RMS for each raster below 15. I also learned how to edit and add polygons; I added a building and road based on the aerial photographs. In addition, I created an inset that includes a multiple ring buffer demonstrating sensitive area around an eagle nest.

Vector Analysis

  This map, made in ArcGIS, illustrates possible campsite locations in the De Soto National Forest near Hattiesburg, Mississippi. These areas are identified as being within three hundred meters of a road and within one hundred fifty meters of a lake or five hundred meters of a rivers. The regions are also color-coded into three area classes, with the darkest orange representing the areas which comprise the greatest percentage of the whole. Throughout this project, I learned how to conduct vector analysis and used a variety of geoprocessing tools to conduct complex selections based on feature attributes and distances. I created the above map using a fixed distance buffer and a variable distance buffer and performed a union of the resulting shapes, then erased designated conservation areas from the selection area.  I also analyzed a group of datasets related to Escambia County public services and superact risk features, conducting actions including using select by location to fi...

Analyzing Bobwhite-Manatee Transmission Line Planning Factors

-
    For my final GIS project, I analyzed factors involved in planning the Bobwhite-Manatee Transmission Line. In 2006, Florida Power and Light sent out a letter detailing their planning of the Bobwhite-Manatee transmission line, which crosses the Manatee-Sarasota County border. There were many issues at play in the decision-making process, and here we analyze four of them: impact of the preferred corridor on environmentally-sensitive lands, the homes and privately-owned lands in and near the preferred corridor, the schools within and near the preferred corridor, and the length and resulting cost of the proposed transmission line. GIS is an excellent tool to spatially analyze all these problems, as it allows one to create and quantify visual representations of land and its features. I used the skills learned throughout the Introduction to GIS course to follow similar methods as might have been used by those originally planning this line in order to explore the same factors and ...

Geocoding

-
    This map displays all schools in Manatee County, Florida, with data including their types, addresses, and contact information. It also includes legal boundaries and roads as reported by the US Census as of 2020. Data relating to schools was taken from the Florida Department of Education's website. Here, I learned how to add XY data to an ArcGIS Pro project and how to geocode. I started with entering simple data on eagle nest locations into an Excel sheet and importing that data to a small map to introduce myself to the process. Then, I moved onto more complex problem solving, as seen in the above map.  Map Link: https://pns.maps.arcgis.com/home/item.html?id=7133ef3a47734654962236f3bad24e90
