Re: [GRASS-user] Unable to export vector data after upgrading to GRASS 8

2022-04-04 Thread Micha Silver 

  
  
If you
  can retrace your steps from scratch, and reproduce the same
  error, it would be helpful to file a bug report.


Here's a
  similar issue:
https://github.com/OSGeo/grass/issues/2187


If you
  have a github account, would you add details of your setup,
  the procedure and the error result there?


Regards,
Micha

  How did you initially create the GRASS Location? Is the albers
  equal 
  area projection described by a standard EPSG code? It appears
  to be this 
  one:
  
  https://epsg.io/102022
  
  
  **IF** that's the correct projection, then you should be able
  to do:
  
  
  echo 
"PROJCS["Africa_Albers_Equal_Area_Conic",GEOGCS["GCS_WGS_1984",DATUM["WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Albers_Conic_Equal_Area"],PARAMETER["False_Easting",0],PARAMETER["False_Northing",0],PARAMETER["longitude_of_center",25],PARAMETER["Standard_Parallel_1",20],PARAMETER["Standard_Parallel_2",-23],PARAMETER["latitude_of_center",0],UNIT["Meter",1],AUTHORITY["EPSG","102022"]]"
  
  | g.proj -c wkt=-
  
  
  
  That long WKT string will reset the projection definition of
  the 
  Location, then you should be able to export OK.

Many thanks for the solution. It worked. However, the v.out.ogr module

How did you initially create the GRASS Location? Is the albers equal 
area projection described by a standard EPSG code? It appears to be this 
one:


https://epsg.io/102022


**IF** that's the correct projection, then you should be able to do:


echo 
"PROJCS["Africa_Albers_Equal_Area_Conic",GEOGCS["GCS_WGS_1984",DATUM["WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Albers_Conic_Equal_Area"],PARAMETER["False_Easting",0],PARAMETER["False_Northing",0],PARAMETER["longitude_of_center",25],PARAMETER["Standard_Parallel_1",20],PARAMETER["Standard_Parallel_2",-23],PARAMETER["latitude_of_center",0],UNIT["Meter",1],AUTHORITY["EPSG","102022"]]" 
| g.proj -c wkt=-




That long WKT string will reset the projection definition of the 
Location, then you should be able to export OK.
