[GRASS-user] 7.5svn: issue with finding EPSG codes for new locations

[Solano Barajas Ramon]

I was struggling with the same problem since some time ago. I’m using a Mac with  MacPorts so currently I have GRASS 7.4.0 installed, but the problem dates from before. 

I just solved this problem: it look like the GRASS routine looking for the EPSG data is not expecting the 1st line of the EPSG text file. Original  content  is:

<metadata> +version=9.2.0 +origin=EPSG +lastupdate=2017-12-17
# HD1909
<3819> +proj=longlat +ellps=bessel +towgs84=595.48,121.69,515.35,4.115,-2.9383,0.853,-3.408 +no_defs  <>
# TWD67
<3821> +proj=longlat +ellps=aust_SA +no_defs  <>
:

So the error comes from the first token, “<metadata>”. I solved this just commenting out that line:

#<metadata> +version=9.2.0 +origin=EPSG +lastupdate=2017-12-17
# HD1909
<3819> +proj=longlat +ellps=bessel +towgs84=595.48,121.69,515.35,4.115,-2.9383,0.853,-3.408 +no_defs  <>
# TWD67
<3821> +proj=longlat +ellps=aust_SA +no_defs  <>
:

In my Mac with MacPorts the epsg file is located in "/opt/local/lib/proj5/share/proj/epsg”.

A word of caution: this file is *not* provided by GRASS GIS itself, but in m case it is provided by the “proj” package, so some collateral errors may arise later.

Cheers.
Ramon.
