Module 3- Geographic Information Systems- Projections

     This week’s lab exercise consisted of two parts. For the first part we familiarized ourselves with Field Maps and learned how to set up our map and app for collecting field data, as well as practiced collecting data offline with the app. After collecting the data, we transformed and viewed the data several ways, online through ESRI, creating a map package that could be viewed in ArcGIS Pro and uploading and viewing data in Google Earth.

    For the second part of the lab we learned about map projections, how different projections account for distortion and practiced making and viewing the same map with multiple projections to compare them. After we created 3 maps with 3 different projections, we made a map layout comparing the projections and showing how the area of 4 different counties located throughout the state was altered based on the projection used.

    This lab assignment gave me a chance to make a map layout based on information given in past assignments, without step-by-step guidance given in this one. It was exciting to see the pieces come together and notice how much more comfortable I'm becoming with the program.
