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.
When I plug the US Census Vectors into Get REST Service Layers, I get the error "The Request was Aborted: Could Not Create SSL/TLS Secure Channel." Any idea on how to fix this? Thanks!1.jpg

It appears the U.S. Census Bureau has moved from HTTP to HTTPS for their web servers. I will need to tinker with Heron's get request code to work with HTTPS and create a "secure channel". For now, the REST components will only work with HTTP websites.
