We have quite a few localities with TRS data. GEOLocate has been helpful for some, but does anyone know of another tool? We have quite a few that are very precise (NW1/4 NW1/4 NE1/4 SW1/4 sec12 T31N R14E), and I haven't found anything besides me, a USGS topo mad pdf, and the TerraGo toolbar that can adequately georeference these. Anything faster (but still maintaining the precision) would be fabulous!
PLSS in Google Earth
Has anybody played around with the TRS overlay for Google Earth available here: http://www.metzgerwillard.us/plss/plss.html Does anyone know of a better overlay (where I don't necessarily have to know the principal meridian or try each possibility manually?) The EarthView Gallery in Google Earth has the 1960s/1970s USGS topo maps that can be overlaid, but I'm still looking for a better solution...
TRS
Here is the one I have listed on HerpNET Resources that works with GoogleEarth: http://www.earthpoint.us/Townships.aspx
Maybe you tried that already? And the single processing site that works quite well but its a pain because you can't batch is: http://www.esg.montana.edu/gl/
This last one is NAD83.
