"The standard North American NAD83 coordinate system is misaligned from the actual Earth, off-centre by about 7 feet. Someone knows where I am, and I'm in the wrong place."

Do you recall what the old geospatial software that was used by USDA and I assume USGS, was it GLASS or something like that?

@GreenFire @GregCocks you might be thinking of GRASS? https://grass.osgeo.org/

Yes, of course. It's been since the early nineties and hadn't thought about it in a long time. Thanks.

@GreenFire @GregCocks it goes back to the 80’s at least! (obligatory link to the 1987 GRASS video narrated by William Shatner): https://m.youtube.com/watch?v=U3Hf0qI4JLc

@tchaddad @GregCocks
Are they still using it though?

@GreenFire @GregCocks no idea about agencies, but people definitely still use it both as a standalone spatial analysis tool, and it is also integrated in QGIS, so fairly accessible from a GUI as well
