Training run route draped over surrounding terrain

A rigorous 11-mile running route mapped precisely onto a three-dimensional terrain model. Serving as a test case, it lays out the precise steps for an upcoming tutorial that is yet to be written. Route: http://www.mapmyrun.com/routes/view/626473440 This detailed map of the running route was created with the assistance of GPXtruder.xyz. A realistic 3D terrain model of the area was designed using QGIS, and a bit of creativity added from the SRTM 1" global digital elevation data, carefully retrieved from the USGS EarthExplorer. Combining these two components within Blender resulted in a comprehensive view of the route and its terrain. Here's an essential tip: If you deactivate the Fit to region option under GPXtruder's Model settings, it will automatically fill in the extent with whatever coordinate system is associated with your chosen map projection. Using this information in your GIS software, you can clip your elevation dataset to match. To work out the scale, check the Max width/depth Size settings in GPXtruder and ensure they correspond with the unit pixel size of your elevation dataset. For simplicity's sake, it is advisable to keep the scale 1:1. Process and settings may be subject to change.
