Week 13 - Georeferencing, Editing, & ArcScene

This week marks the last official lab assignment before the final. For this lab we georeferenced aerial photos to buildings and roads associated with the UWF campus, created building polygons and road polylines, and created multiple ring buffers around an eagle's nest. To top it all off, we overlaid data on a DEM in ArcScene - which is a 3D mapping program offered by ESRI.

Georeferenced aerial view of the UWF Campus - and the Eagle Nest location!

Notes on Map 1

The first map shows two separate data frames that contain aerial views of the UWF Campus. The aerial image on the left was georeferenced, and the items in red indicate those features that were digitized during the lab. I've decided to separate out the digitized data from the non-digitized data by color, so that both of my maps sort of flow together.

The data frame on the lower right shows the location of the eagle's nest in relation to the overall boundary of the UWF Campus. The aerial image in the background was provided by ESRI. During the lab I was wondering who in their right mind would ever think building student housing in a wilderness sanctuary would be a great idea... and then I saw that the eagle nest location is right on the university boundary. It sort of makes sense now (but not entirely - I mean, who couldn't see that roadblock coming?).

Notes on Map 2

The second map shows a 3D snapshot view of the UWF Campus, with the digitized buildings 'highlighted' in red. I kept the symbolization and overall map appearance the same as the first map. The buildings were extruded off the surface, and all visible layers are resting on top of a DEM (not immediately visible). Due to the way ArcScene works it was not possible to provide a scale or north arrow... it's almost kind of liberating! Technically the map above is a screenshot of what was visible in ArcScene, with the finishing touches made in ArcMap.
