ELK By: Sam & Paul
Elk was created to facilitate bringing mapping data into Rhino via Grasshopper. It does this by allowing you to import OSM data files from OpenStreetMap.org. The current version 0.3 allows you to get data either downloaded from OpenStreetMap (limited to 50,000 points) or stream it using the Overpass API to get larger swaths of data, however large amounts of data can greatly increase the solving time (a few million points took over an hour). I’ve only tested data from these two sources, so using files from other locations may or may not work depending on how the data’s structured.
The second part of it is a topo generator using Shuttle Radar Topography Mission (SRTM) elevation data. The data can be accessed from the USGS website. The resolution of available elevation data varies, with data for the United States available in 1 arc second increments (about 30 meters) and the rest of the world available at a highest resolution of 3 arc second increments (about 90 meters)
