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 everyone,
Thank you for this superb plugin! I have a few questions regarding its configuration, here they are in order:
I managed to import GIS vector data from a specific server. However, the datas were encoded in a different projection than Heron's. Is it possible to modify the projection system so that the geometries are displayed correctly?
Only 1000 objects are displayed out of several thousand. Is it possible to display all the objects contained in the layers?
Can someone provide me with more details on how to configure the boundary curve? Do the XY coordinates of the four corners of the boundary rectangle correspond to precise GPS coordinates in the WMS84 projection system?
Many thanks!
