Georeferencing, Editing, & ArcScene

   In this lab, the objectives were to: georeference data using the Control Points tool in order to distribute control points, georeference an unknown raster image of the UWF campus to known vector data (buildings and roads of the campus), interpret Residual and Root Mean Square errors, digitize a new building and road feature, practice polynomial transformations, create a hyperlink in ArcGIS to data stored on a personal drive, create Multiple Ring Buffers, customize an ArcMap toolbar, and overlay vectors and rasters to a 3D environment. In this lab, 2 maps were created.

Georeference of the UWF Campus

   This map shows the UWF campus georeferenced on the right, and an eagle nest buffer zone on the left. For UWF map, control points were used to align the raster with the vector points in order to assign a spatial reference. Two new features were also added through the Editing toolbar. The eagle nest map utilized the MBR tool in order to create a buffer of 330 feet and 660 feet around the nesting site. The buffer represents the distance the nest site needs in order to be undisturbed by development.

3D Map of the UWF Campus

   For this map, ArcScene was used to overlay the rasters and vectors to a DEM. Vertical Exaggeration was added to enhance the height of the buildings. The 3D map was exported as a 2D image and imported into ArcMap to add the final map elements. The POV is of the two new features created in the lab.
