Intro to GIS: Week 13 - Georeferencing

In this week's lab, we learned about georeference, editing, and ArcScene.To show that we understood the material, we created a map of UWF's Campus. We had to merge the raster data (UWF's North and South Aerial images) and the vector data (building features, roads, and eagles nest data) as one dataset. To do this we used the 'Georeferencing' tool to connect the ' UNKNOWN' (raster) data to the 'KNOWN' (vector) data. After geoferencing the data, we had to edit some of the presence data that was not documented which was the UWF Campus Gym and Campus Lane roadway. The 'Editor' toolbar was quite useful for creating new polygons for the gym building and connecting Campus Lane with other existing roadways. Another purpose of this map was to show where an eagles nest was located to preventing any kind of destruction to the eagles' habitat. If any construction were to take place, we created a multiple ring buffer zone showing the extent of the eagles' nesting ground. The first buffer ring extended to 330ft and the second one extended to 660ft. Once we were finish mapping out the data, we started to dabble in ArcScene which allowed us created a 3D effect and add a different angle of perspective to the data that we were manipulating. We used ArcScene to created 3D presentation of the DEM of UWF's Campus, buildings, and roadways.
