Are section lines available in Google Maps?

[E. V.]

General Map Maker Forum:  Are section lines available in Google Maps?

 

Section lines are used to define all land in the U.S.  The Department of Interior Geological Survey has supplied the data for all the section corners in the U.S., which are generally 1 mile apart.  So, whenever anyone has a survey map, those corners will always be shown or referenced, and if they were visible in Google Maps it would be much easier to draw an accurate map for any particular site using Google's Map Maker. 

 

I understand that it would be difficult to perfectly align the survey data with the satellite imagery, just as it’s difficult to align the digital road data with the aerial imagery currently; which would not be a good reason to eliminate the slightly offset digital road data.  Naturally, I could use the section lines and corners as references and make alignments with the satellite imagery as everyone does currently, if that’s best. 

 

Undoubtedly, an algorithm will someday be available, perhaps based on a few thousand known reference points, to align the roads and satellite imagery, as well as the section lines.  Thank you for any information.   2/24/2013

You could find information on that here: http://www.geocommunicator.gov/GeoComm/lsis_home/home/

This is United States data, so it's in the public domain.

There are some KML files on that site, but they are way too large for Google Maps / Google Map Maker overlays by themselves, meaning intended for Google Earth only. You could try splitting the KML for use with the Map Maker overlay feature. See https://groups.google.com/d/topic/google-mapmaker/m0EWir1h0aA/discussion for instructions.

More information on the Overlay feature in Map Maker is available here: http://support.google.com/mapmaker/answer/155420
