This page maps the United States Public Land Survey System onto Google Earth. For more information about the land survey, Wikipedia has a good article. You can read about locating parcels at Earth Point Blog.

There are two data sets to choose from, "BLM" and "National Atlas".

BLM Township, Range, and Section

Displays townships, sections, and quarter-quarter sections if you zoom in close enough (most, but not all areas have quarter-quarter sections mapped). Calcuates area, centroid, and corner points. You must zoom into the central or western United States to see the data.

New: Options... (hide/show icons, labels, quarter/quarters; change colors)

Convert Township, Range, and Section to Latitude and Longitude

Enter Township and Range. Optionally enter Section. Google Earth flys you there using BLM data. Hint: pause for a moment after choosing each of the criteria. This allows the data to be loaded into the drop-down boxes.

If you want to see the surrounding townships, then once you have clicked the "Fly To" button, come back and click the BLM or National Atlas "View on Google Earth" button. Free. User account is not needed.

Convert Latitude and Longitude to Township and Section

Enter latitude and longitude. Find the corresponding township and section. The BLM database is searched first. If nothing is found then the National Atlas database is searched. Note that the National Atlas database has only townships, no sections.

Latitude		Examples: 43°38'19.39"N, 43 38 19.39, 43.6387194
Longitude		Examples: 116°14'28.86"W, 116 14 28.86, -116.2413513

National Atlas Township and Range

Full coverage of the United States Public Land Survey. Good alternate if there is a gap in the BLM data, but with less accuracy. Townships only, does not have sections or quarter-quarter sections. Calcuates area, centroid, and corner points. You must zoom into the central or western United States to see the data.

Hide Icons

When making a screen shot, it might be helpful to hide the icons. Be sure to include the trademarks displayed at the bottom of the screen in any published material.

Click just once. The screen is updated as you move around in Google Earth. Free. User account is not needed.

Hint

In mountainous areas it might be helpful to turn off the terrain layer in Google Earth. Otherwise, the survey grid can look distorted as it shapes itself to the earth's surface.

Information: BLM Township and Range

The Bureau of Land Management (BLM) cadastral survey program is responsible for the official boundary surveys for all federal agencies in the U.S. that together manage over 700 million acres. The Public Land Survey System also called the Rectangular Survey System is the foundation for many survey-based land information systems.
