Florida Projections Comparison Map and Data Collection with ArcGIS Field Map

 

In this weeks lab assignment, we were directed to compare map projections visually. The three maps above portray four counties in the state of Florida, as listed in the legend. Each one of these maps shows a different map projection of the same area. In the table at the bottom right corner of the map, the table shows the area in square miles in each county within each map projection. This shows that not all map projections are meant to showcase just any area. For example, in Polk County, in the UTM map projection the area in square miles is 2022.409309, and in the Albers map projection the area in square miles is 2010.435206. The best map projection for the state of Florida would be the Universal Transverse Mercator map projection.

For this weeks lab assignment, we had to create an empty feature class, create domains, choose symbols for data collection, share the feature class to a web layer, and collect data in the field. Above is a view of the data I collected in the field. Each point is a street sign where I visited, collected the GPS points, filled out the required fields, and snapped a picture of the street sign to show the condition. This assignment was educational because I understand how collecting data in the field with field maps because it is currently my profession but I started this program to learn the behind the scenes of how these maps are created to collect data.
