This is the first release of an add-on which enables the import of GIS data from various sources into the Rhino/Grasshopper environment, located, scaled and cropped based on an Earth Anchor Point and a clipping polygon. Sources of GIS data include Shapefiles, USGS IMG/HGT Elevation files and ArcGIS REST Services over the web.
The add-on includes eight components in two categories:
GIS REST
GIS Tools
Special thanks go to the vibrant GH community, the masterful guidance of Andrew Heumann and endless patience of George Waters.
Hi Brian!
Thanks for such an awesome plugin! I am new to working with GIS information and the Rhino/GH GIS workflow and I am experiencing some issues with importing a shapefile. I realized that the skewed nature of the shapefile was due to the difference in CRS ( mine was initially in NAD83. But i went into QGIS and reprojected it to WSG84/ Pseudo Mercator) the ImportVector component reads the source file to have this CRS, but the building outline is still skewed. Any tips on how to fix this? I don't know what the issue is really... Attached screenshot and zip folder to shp. files!

Hi! I'm glad you're finding Heron useful. Try setting the Earth Anchor Point (SetEAP) first before using ImportVector. It seems to work when I tested it. Also, you shouldn't have to reproject in QGIS, you should just be able to use the original shapefile. I'd be curious to test this as well. Can you post the original shapefile?

Hi Brian!
I'm very happy to see such a progress with the development of your plugin. Great news! Looking forward for the documentation and other updates! However could you clarify how to use userSRS while importing shp files? I see WGS84 string input, EPSG:4326 string works as well. But other variants don't work. Is it possible now?
