Thanks for the response. I hope this can stimulate a discussion. “Project” is a good option too. As I outlined in my message, there are 2 aspects to this: 1) changing the wording in the GUI where “location” is used now, and 2) ultimately changing the location= argument in the modules where it is used.
I’ll take a look at the WIKI. Michael _________________________________ C.

Here is a summary of some ideas from the recent discussion on the list and in our lab: https://trac.osgeo.org/grass/wiki/wxGUIDevelopment/New_Startup<https://urldefense.proofpoint.com/v2/url?u=https-3A__trac.osgeo.org_grass_wiki_wxGUIDevelopment_New-5FStartup&d=DwMFaQ&c=l45AxH-kUV29SRQusp9vYR0n1GycN4_2jInuKy6zbqQ&r=lk-7X7CEOMDN8GaGVhiDsuO6gEp1wbG6nfT1XEEEtR0&m=roKvIbpelz8ddB2ERg5UJAHAkTJZvXky1tobOjigfBw&s=5C1rzhMVVbSX3gcHS56JRno6pJIwewY_Cev_NPBmtwQ&e=> as you can see the proposals refer to a project (it was also called "project location"), but as we discussed it this week in our lab it can get complicated. CRS may be confusing to new users as well because there can be many different locations with the same CRS for different projects. Feel free to add summary of your ideas to the trac linked above, Helena On Jun 1, 2018, at 6:51 PM, Michael Barton <[email protected]<mailto:[email protected]>> wrote: As one of the most venerable desktop GIS packages and perhaps THE most venerable still in existence, GRASS has some quirks that harken back to its origins long ago. Most are simply quirky. But the folder hierarchy called a “location” is very confusing in today’s GIS world. Originally, it did primarily refer to maps referencing a geographic location in the world. Although that meaning still exists in the ‘default region’, GRASS locations primarily refer to a coordinate reference system (CRS). In fact, while the CRS of a location cannot be changed (unless you manually alter some of the files in the directory, at the risk of making maps unuseable), the default region can be. So a location now refers to a fixed CRS and a changeable geographic extent. Use of the anachronistic term “location” to refer to a CRS is a quirk that makes GRASS more confusing to initial users. I suggest we consider beginning to migrate the term “location” to “CRS”. The term “location” does not occur in a large number of module interfaces: those (like g.mapset) for changing to a new working directory on the fly, vector and raster reprojection modules, and maybe a couple of others. It occurs in the GUI at startup, in the location wizard of course, and in some tools for georeferencing. We could initially maintain backward compatibility and increase understandability by simply referring to “location” as something like “location/CRS” where ever it shows up in the GUI, but leave module arguments alone. A next step would be to have modules that require “location=” as an argument accept either “location=” or “CRS=”. And maybe that is enough. We could keep “location” where it currently occurs in existing command modules and scripts as a legacy option. Likewise, we could keep it in current code, only changing during code rewrites. Any new modules that need to refer to this file hierarchy would use “CRS”. Thoughts? Michael ______________________________ C.
