Week three lab: projections

This week, we had two distinct lab projects. In the first, I generated a map of of a local area in ArcGIS using a world topographic map, then exported it to Arc Online, which I then accessed using a smartphone app called Field Maps. Using Field Maps, I geotagged and photographed multiple public safety features (fire hydrants), then exported them back to Arc Online. Then, I learned how to export my finished map as a map package and a Web Map, and export my data as a KML file to upload to Google Earth.

In the second unit, we learned about map projections, and I created a map of Florida using three separate projections, and compared the area calculations of each. We learned about how ArcGIS interprets data in different projections and coordinate systems, and how it will draw a map in the absence of a defined coordinate system.
