Anybody know how to get digital mapping data into a mesh or a heightmap? In fact, does anybody know where to get it from? |

DEM files are pretty easy to read, typically raw dumps of 2D float or int arrays. Google GTOPO30 and SRTM30Plus for sources of earth data. Last edited 2011 |

Theres a tutorial somewhere on the web (sorry don't have a link to hand) where you can select a region from google earth to export the geometry data using a plugin and convert using microDEM IIRC with hints on how to make the data readable for common useages such as height maps. Last edited 2011 |

John, for my BlitzTiles project I created a PDF How to create real Terrains for BlitzTiles in which I desribe how to extract real data from the web, import/export it with 3DEM and Wilbur and create a map in L3DT. L3DT is able to export a mesh which should be the easiest way. The Example from the PDF: The Grand Canyon made with USGS data If you have questions just ask me. EDIT: The URL for Wilbur has changed, find it here: http://www.ridgecrest.ca.us/~jslayton/wilbur.html Last edited 2011 |
