Hi
My shell/python script that extracts the location of parking icons from the database does no longer work: /home/kayd/parkingicons/generate-parking-icons.sh
The error message is:
psycopg2.InternalError: transform: couldn't project point (2.79772e+06 8.45105e+06 0): failed to load NAD27-83 correction file (-38) HINT: PostGIS was unable to transform the point because either no grid shift files were found, or the point does not lie within the range for which the grid shift is defined. Refer to the ST_Transform() section of the PostGIS manual for details on how to configure PostGIS to alter this behaviour.
To narrow down the problem please try this sql statement:
osm_mapnik=> SELECT ST_Y(ST_Transform(ST_line_interpolate_point(way,0.5),4326)) FROM planet_line WHERE osm_id=27720543;
ERROR: transform: couldn't project point (1.12026e+06 6.38855e+06 0): failed to load NAD27-83 correction file (-38) HINT: PostGIS was unable to transform the point because either no grid shift files were found, or the point does not lie within the range for which the grid shift is defined. Refer to the ST_Transform() section of the PostGIS manual for details on how to configure PostGIS to alter this behaviour.
Of course this query worked before and it seems to be an installation problem of the new postgres/postgis version:
