How it works.
- Earth Point gets it data from BLM shape files available at http://www.geocommunicator.gov/GeoComm/lsis_home/home/index.html
- Earth Point formats the data, stores it in a database, and manages the interaction with Google Earth.
Note: I have spot-checked the data, but I have not checked all 17 million records! If you find an inconsistency, please let me know.

- Open Google Earth. Zoom into an area of interest over the western United States. The picture below is near Blackfoot, Idaho. It was selected because irrigated crop circles, which follow the pattern of land ownership, are generally laid out within the boundaries of quarter sections.
- Go to www.earthpoint.us/Townships.aspx.
- Scroll down to "BLM Township, Range, and Section."
- Click the "View on Google Earth" button.
- The screen switches back to Google Earth.
