I'm using geemap to display a raster on a created map. This lib use xarray_leaflet to display the raster and this lib will end up using rasterio to manipulate the .tif file.

When I launch my display :

m = geemap.Map()
m.add_raster(clip_map, colormap='terrain', layer_name='gfc')

I get the following error :

CRSError: Unable to open EPSG support file gcs.csv. Try setting the GDAL_DATA environment variable to point to the directory containing EPSG csv files.

This error is everywhere on SO so I tried to verify if my GDAL_DATA env variable was coorectly set :

import os
import stat
gdal_data = os.environ['GDAL_DATA']
print('is dir: ' + str(os.path.isdir(gdal_data)))
gcs_csv = os.path.join(gdal_data, 'gcs.csv')
print('is file: ' + str(os.path.isfile(gcs_csv)))
st = os.stat(gcs_csv)
print('is readable: ' + str(bool(st.st_mode & stat.S_IRGRP)))

# out 
# is dir: True
#is file: False
#FileNotFoundError: [Errno 2] No such file or directory: '/usr/share/gdal/gcs.csv'

going to the glad distrib inb the NEWS file, I read that they removed lots of file in 3.0 including gcs.csv. So it's no longer included in my folder.

Is there a workaround ?

setup

rasterio==1.1.5  
python==3.6  
geemap==0.7.9  
gdal==3.0.4

This is a known issue of rasterio (in conda for example)

Answers are given in

and many more.

Try setting the GDAL_DATA environment to a path which contains a gcs.csv file (use search to find a path)

os.environ['GDAL_DATA'] = '.../site-packages/rasterio/gdal_data'

Or

os.environ['GDAL_DATA'] = '..../site-packages/fiona/gdal_data'

thanks to @gene for the answer
