• Cliff Island GPS Field Data and Geologic Map Construction
• Cliff Island Geology Map – ES/GE 217 • Overview of assignment • The purpose of this lab is to make a really
nice looking bedrock geologic map of part of Cliff Island in Casco Bay. You will be collecting geologic field data on Cliff Island, making the digital map in ArcMap and preparing the final publication map in Adobe InDesign.

Finished geologic map of Cliff Island made by a student
A mapping exercise like this provides students with….
Experience using GPS linked with field data collection
Techniques in symbology and topology in Arc
Opportunity to think spatially about earth materials
Chance to make a publication quality final product geared for both the geologist and lay public
You can make a digital map of any earth materials near campus
