Geograph MA for iOS

By Integrity Logic $4.99

Developer's Description

The ultimate app for Geography/Geology amateurs and professionals."
- Mel Martin, TUAW.com

Do you know which state assembly district you are in? Which school district? Where is the closest railroad? Is there a mine nearby? What kind of rock are you sitting on?

Geograph MA is the edition of the popular GIS (geographic information system) covering the commonwealth of Massachusetts. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the geography and geology of the Bay State. You can combine various data layers, zoom in and out, and get a lot of details about the physical and human geography of Massachusetts.

While this is a professional-grade tool, it can easily be used by anyone curious about their environment.
