Module 6 - Network Analysis & Spatial Statistics - Georeferencing, Editing, & 3d Lab

 Module 6 labs consisted of georeferencing a series of raster data images in the form of aerial photographs to vector data in the form of buildings and roads. 

Though scaling and control point linkages in both 1st & 2nd order polynomials, I was able to achieve georeferenced images with RMS values well below 15 and below 10. RMS/RMSE, or root mean square error, is a measure of the differences between the predicted or calculated values and the actual, or observed/measured values (between the data you want to georeference and the data that already exists). The difference between each control point linkage is known as a residual and the RMSE is an aggregation of all the residuals for all linkages between the data. 

Once the images were georeferenced, I utilized the editing functions within ArcGISPro to add a new polygon for a building and road that were not present within the vector data. I also added the data attributes prompted by the lab instructions so that would be shown in the final layout as labels.

Finally, I added a multi-ring buffer for the eagle nest location just outside of the UWF campus area I was working with.

My final map layout for the lab exercise:

My map features the vector data for all buildings and roads within UWF's campus and the correct building numbers and road names are labeled from the data attributes from the layers' metadata. The aerial image uwf_n.jpg makes up the upper half of the main focus map and uwf_s1 makes up the lower half. Georeferencing information regarding each raster image is located in the middle of the layout all the way to the right. There is also an inset map featured showing the location of eagle nest ES003 near UWF's campus with a zoomed in view showing a multiple-ring buffer at 330 and 600 feet that represents a conservation easement and protected area from development, respectively. There is also a semi-transparent survey map for Heritage Hall at UWF that is georeferenced within the main map focus as well.
