Turn a GPX track into a printable terrain model: the Pennine Way from Edale to Crowden, draped on Environment Agency LiDAR, with the route raised, engraved, or printed as a separate colour inlay. Every STL is proved watertight before it is written.
Make a 3D terrain map in Python with PyVista. Turn an Environment Agency LIDAR DEM into a StructuredGrid, drape a Sentinel-2 image on it, compare vertical exaggeration and lighting, drape a GPX route over Striding Edge, and render off-screen to PNG and a rotating MP4 on Windows, macOS or Linux.
A MovingPandas tutorial on one day of real AIS vessel tracks in Puget Sound: 277,574 GPS fixes from 703 vessels turned into trajectories, with speed and direction, outlier cleaning, stop detection at ferry terminals, splitting into 148 trips, Douglas-Peucker against time-aware generalisation, a flow map of 319 aggregated flows, and reading and writing GPX.
