Module 6: Georeferencing

 

    

    This week, we learned about georeferencing and the related tools in the geoprocessing tab. We added different layers and created a georeference from an aerial image of UWF. While completing the task, we examined different transformations and their various requirements. We also used Root Mean Square Errors and examined how this affects maps and different error ranges. For this, you have to learn how to balance between error values and the actual appearance of the map. 

    While working on editing the georeference, we created a new polygon feature and digitized it with various digitizing tools. The final tool we used for this map was a buffer in order to create a multiring buffer zone around an eagle's nest on the UWF Trails. The inner buffer is 330 ft, and the outer buffer zone is 660 ft. My final 3D map of the campus and Eagle Nest Map is shown above. Both have the georeferenced layer used, but it was more pronounced on the 3D map. Georeference was a bit tedious as you had to correct errors in the georeferencing layer to the aerial image, but that was the most difficult task as we could use the skill learned in the previous lab for the rest of the map imaging.
