3D Map of UWF Campus Roads and Buildings and Conservation Easement Map

This week was actually fun! Never thought I would say that again in this course. It seems that much is coming together better since the weeks of the dreaded Projections fiasco. For this lesson, we learned about Georeferencing using the Control Points tools to reference the unknown elements of raster data to known elements of vector data. We learned that it is important to not only make sure that the Root Mean Square errors are within acceptable limits (below 15) but also making sure there is an accurate appereance. Working within the attribute tables gave us the information we needed to tweak the points until we got what we needed. We then learned how to digitize elements such as roads and buildings, open and end editing sessions and lastly create 3D map images utilizing ArcScene. The first map below shows the 3D efforts:

This second map shows the work related to using Analysis Tools - Multiple Ring Buffer Tool and Hyperlinking data. We created a map showing a Conservation Easement linking to an Eagle's Nest image. My RMS data are different because I had to recreate the process in order to create this map. I worked from my office computer for the 3D map above but did not have a way of successfully transferring the data for the map below. This has been one of the added complexities of trying to do this work in different environments. Between UWF, my office and home computer there are no seamless ways to combine all the information necessary to complete the overall tasks. I did get extra practice so I guess it is a good thing in the long run.
