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.
Hello,
Thank you for this very interesting plug-in,
I would like to work with a .shp file projected in lambert93 (EPSG: 2154). I am unable to use the import vector function with heron version 0.3.6. Should I use a custom CRS? Version 0.2.0 works with .shp files in the lambert93 coordinate system, but version 0.3.6 does not.
I would like to use version 0.3.6 since there are more features, I especially need the ESRI REST Geocode function which does not work in version 0.2.0.
I also cannot reproject my .shp data manually to WGS84 using QGIS, although it works, since I have thousands of files.
Do you have a solution to use the import vector function in the lambert93 coordinate system?
Thank you

Hi Paul,
There is definitely a bug in my code that I will be looking into over the weekend. The component only seems to work without a boundary, setting cropIt to false and with the default SRS of WGS84. This is related to the bug reported by Evgeny here. Thanks for posting the files at issue, they will help me troubleshoot.
