Hi List,
When I export a vector using v.out.ogr, I'm unable to assign an output
layer name when the output format is 'ESRI_Shapefile'. For example:
v.out.ogr input=grid_clip output=grid_clip.shp output_layer=sub_grid
format='ESRI_Shapefile'
Exporting 4 areas (may take some time)...
100%
v.out.ogr complete. 4 features (Polygon type) written to <sub_grid>
the message indicates that it has been written to sub_grid, but the
output from ogrinfo indicates that is hasn't been updated:
ogrinfo -so grid_clip.shp
INFO: Open of `grid_clip.shp'
using driver `ESRI Shapefile' successful.
1: grid_clip (Polygon)
However, the above process works, and the correct layer name is written,
when the output format is GeoPackage or SQLite. I can update the layer
name subsequently with ogr2ogr, but it would be preferable if this could
be avoided. I'm using GRASS 7.4.0 (2018) on Ubuntu 18.04 (bionic).
Any advice appreciated.
I don't think shapefile supports the notion of layer names as each layer
is in a separate file, so file = layer, and filename = layername.
v.out.ogr could possibly be enhanced by including a warning about this
when the user tries to assigne a layer name to a shapefile.
