Lab 3 Data Collections and Projections

This week we worked with Projections and ArcGIS Field Maps. For the projections we learned how flat maps are taken from a round object also known as the Earth. From this lab we learned that certain projections create distortions depending on how the map information is collected and the distortions can change the area, direction, and shape highlighting the issues with transposing this information and using it for analysis. In the Lab we show three different projections at the same scale to show the visual differences and including a table showing the difference in area among several counties.
