PLSS in Google Earth (PLSGE)
This page briefly describes a free application that runs in
the Google Earth desktop client. Please install
and return to this page to learn more.
The principal component of PLSGE is a Google Earth implementation of the
Public Land Survey System (PLSS)
Cadastral National Spatial Data Infrastructure (PLSS CadNSDI)
It retrieves multiresolution images of the PLSS from the
Bureau of Land Management (BLM) .
Position the area of interest (AOI) in the viewer.
Check the radio button beside the Alaska SDMS, Townships,
or Special Surveys network link. Use the Townships overlay to find
townships and sections. Use the Special Surveys overlay to find other divisions.
On subsequent uses, reposition the AOI and ensure that the network link
is checked and selected.
When Refresh Mode is Automatic, the
overlay is refreshed two seconds after camera movement stops.
When Refresh Mode is Manual, choose Refresh
from the Edit menu, or right-click
and select Refresh in the context menu

Figure 1. Townships Overlay
Coverage includes Alabama, Alaska, Arizona, Arkansas, California, Colorado, Florida, Idaho,
Illinois, Indiana, Iowa, Kansas, Louisiana, Michigan, Minnesota, Mississippi, Missouri,
Montana, Nebraska, Nevada, New Mexico, North Dakota, Ohio, Oklahoma, Oregon, South Dakota,
Utah, Washington, Wisconsin, and Wyoming.
PLSGE also includes protracted townships provided by the Alaska Spatial Data Management System
(SDMS) and a facility
to draw approximate PLSS boundaries with links to BLM land records.
The Point Search network link is a Google Earth implementation of the PLSS CadNSDI
This feature should be used in conjunction with the Townships overlay to ensure that
the point of interest (POI) is contained within a first division boundary.
Position the POI in the center of the view. One way to
do this is to double-click an unmarked location. To precisely position the
POI in the center of the view, add a placemark at the desired location;
then edit the properties of that placemark and reset the view
For best results, disable automatic tilting (Tools, Options, Navigation,
Do not automatically tilt while zooming) and minimize elevation
exaggeration (Tools, Options, 3D View, Elevation Exaggeration, 0.01).
Check the box beside the Point Search network link.
The section boundary that contains the POI will be added to the
Search Results folder.
A successful point search will also update initial values in the
TRS Search form.
On subsequent uses, reposition the POI and ensure that the network link
is checked and selected. Then choose Refresh from the Edit menu,
or right-click and select Refresh in the context menu

Figure 2. Section Geocoder
The TRS Search network link is a Google Earth implementation of the PLSS CadNSDI
This feature should be used in conjunction with the Townships or
Special Surveys overlay to ensure that the requested township, section, second division, or
special survey exists. Use the Townships overlay to find townships and first divisions.
Use the Special Surveys overlay to find other divisions.
Optionally, use the Point Search network link to preset initial values to
the section level.
Click on the TRS Search folder name to open a form with input fields for state,
meridian, township, range, section, second division, and special surveys.
Mouse-over input fields for brief instructions.
Press the Search button on the input form to add the requested parcel
to the Search Results folder.
To save geocoder results from one Google Earth session to another, right-click
on Search Results
and select Save to My Places
