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.

Evgeny,
What is the coordinate system of the original data before being reprojected? Can you post a link to source? What are the red lines the meshes are not matching to? Apologies if I don't quite understand the issue.

Hi Brian,
The first image is a comparison of the polygons from Heron (in red) and the meshes from InfraWorks (in yellow - selected)
The second image compares the polygons from Heron (in white) and the exported polygons from QGIS (selected hatches in yellow)
The CRS I have used is EPSG:32637 (the area of interest is located in Moscow). Here is the shape file with reprojected data https://www.dropbox.com/s/kwszn5yf958f4ep/buildings_2017-01-10_3263...
It would be great not to have this slight rotation. I see it originates from specific use of 3857 within the plugin. Thank you!

Hello, I am having trouble with a few components, I've used Heron in the past and it works wonders, however, with the RESTGeocode, it's returning the following error: 1. Solution exception:Input parameter index [-1] too low for Component ESRI REST Service Geocode
No matter the location I type I get no return from location or LAT & LONG.
Any idea what's going on?
