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,
Unfortunately, the ESRI geocoding service recently switched its endpoint from "http" to "https", so the one that's embedded in the component will no longer get results. This is the case for a few of the other components as well. I am, however, actively developing updates to Heron on Github (https://github.com/blueherongis/Heron) and making them available via the Yak Package Manager and this issue has been addressed with Heron 0.3.2. If you aren't familiar with the package manager, you can access it by typing "TestPackageManager" in the command line for Rhino 6 and "PackageManager" for Rhino 7. Once the dialogue pops up, you can search for "heron" and install directly from there (no need to go to Food4Rhino). Before doing so, I would delete all existing Heron files from the Grasshopper Libraries folder to avoid any conflicts. Once you have the latest version of Heron installed, you will find you will need to replace the Heron 0.2.0 components with new ones. Also note that there's a lot more functionality with the new version, but I have yet to document it, so if you need any help understanding how things are working, please let me know.
