Not really sure this belongs in the Gallery, but I just imported a bunch of Natural Earth ESRI shapefiles using the new importer I wrote for Grasshopper2. So far this just includes the geo-physical data, cultural data I may or may not do in the future. All data sets have been merged into categorised Rhino files with properly named layers and sublayers.
All data is purely 2D, elevation sets have not been included. I have not post-processed the data in any way, specifically I have not merged adjacent polylines that are clearly supposed to be a single region.
You can download the files I produced (Rhino 6 3dm and worksession files) from
our servers my dropbox:
