Public Land Survey System (PLSS)
Requires Google Earth Version 5.0 or later.
The principal component of PLSS is a Google Earth implementation of the National Integrated
Land System (NILS) GeoCommunicator
map service.
It retrieves multiresolution images of the Bureau Of Land Management
(BLM)
Public Land Survey System (meridian, township, range, section, aliquot, and lot).
-
Position the area of interest (AOI) in the viewer.
-
Check the radio button beside the Townships or Meridians network link.
-
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. Check the Meridians overlay to display the
coverage area.
The NILS map service will not return an image for the Townships overlay if the target
resolution is greater than 1 millidegree per pixel. Service parameters are adjusted to allow
township displays at target resolutions up to 2 millidegrees per pixel with a corresponding
decrease in label size. Zoom in to display sections, aliquots, and lots where available.
The PLSS application also includes a facility to draw approximate section boundaries as KML
LineStrings with centrally located information icons.
Section Geocoder
Point Search
The Point Search network link is a Google Earth implementation of the GeoCommunicator
Derive LD and Find LD
data services.
This feature should be used in conjunction with the Townships overlay to ensure that
the point of interest (POI) is contained within a section 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.
-
Check the box beside the Point Search network link.
The section boundary that contains the POI will be added to the Saved Sections folder.
-
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.
Neither Alaska nor some coastal areas of the conterminous US are currently supported by
the Derive LD data service.

Figure 2. Section Geocoder
TRS Search
The TRS Search application is a Google Earth implementation of the GeoCommunicator
Find LD
data service.
This feature should be used in conjunction with the Townships overlay to ensure that
the requested section exists.
-
Click on the TRS Search folder name to open a form with
input fields for state, meridian, township, range, and section.
-
Press the Search button on the input form to add the requested section
to the Saved Sections folder.
-
Double-click on the TRS Search folder description to fly to the section.
Alaska is not currently supported by the Find LD data service.
Note: To save geocoder results from one Google Earth session to another, copy
the Saved Sections folder and paste into My Places.
All images and data are retrieved from remote servers. Data errors,
accuracy, and availability are beyond the control of this application.
