How to retain layer information in Shapefile to Rhino

The PINVOKE error can usually be fixed by loading Heron from disk. See this thread:

Import Vector error

Hi @Dongyeop_Lee , I have seen this happen when installing Heron through the package manager, which is the preferred method (related Heron Github issue). Basically, Heron is looking for GDAL libraries and can’t find them when they are installed in the packages folder. The work-around for this issue has been the following: in Grasshopper Settings>Solver>Plug-in Loading, scroll down to Heron and click the little puzzle piece icon so that you see the disk.

Also, when referencing the GDB folder location for the Ogr2Ogr component, try leaving off the last “\”.

Here is an updated definition referencing the Land Use Clipped SHP file you uploaded.

@Erik_Beeren It would be nice if @user1919 was just interested in the Land Use layer you found. The windows side of my 2015 MacBook Pro is struggling with the larger datasets.
