PLSS in Google Earth (PLSGE)
The principal component of PLSGE is a Google Earth implementation of the Bureau of Land Management (BLM) GeoCommunicator map service. It retrieves multiresolution images of the BLM Public Land Survey System (PLSS). Protracted townships west of the antimeridian are provided by the Alaska Spatial Data Management System (SDMS).

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. Click on the Availability folder name to test the PLSS map service.
The 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.
PLSGE also includes an implementation of the GeoCommunicator Identify service and a facility to draw approximate PLSS boundaries, many with links to BLM land records. Land records are currently available for Alabama, Arizona, Arkansas, California, Colorado, Florida, Idaho, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Utah, Washington, Wisconsin, and Wyoming.
SECTION GEOCODERPoint 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. Click on the Availability folder name to test the Find LD data service.

Figure 2. Section Geocoder
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 or Special Surveys overlay to ensure that the requested township, section, or subsection (aliquot, lot, donation land claim, exchange, homestead entry, land grant, mineral survey, protracted parcel, small holding claim, townsite, tract, unprotracted parcel, or water) exists.
