Difference in horizontal resolution can be important. It is not clear (to us) whether radar models that measure the tips of trees and houses are DTMs or DSMs.
Digital surface models (DSM) include things on top, like buildings). Digital terrain models (DTM) include just the terrain. described in Maperitive for laser cutting and 3D printingĪ digital elevation model (DEM) is a digital representation of a terrain surface that is created from elevation data. 3D PRINT TERRAIN FILES REGISTRATION
Laser cut a model sliced with Autodesk 123D Make (free software, registration required). Landform Library for Educators by mfritz is a very good starting point. Get ready to print STL models for some famous spots. Models can be huge and slicer settings must be adapted to avoid print aborts (in particular nozzle getting stuck in plastic). This is not as easy as it seems and for two reasons. In some cases you might want to emphasize horizontal distances by a factor of 2, 3 or 4. Adjust the Z-axis (if not done before). Add a box to the bottom if there is a need. Crop x,y direction if there is a need. 3D PRINT TERRAIN FILES FREE
using the free Meshlab program to do that (see below) If it is larger, consider reducing the triangles (if not done before), e.g.
If the model represents a very small area you can slice it "as is". use Netfabb (repair tool) or Meshmixer ("make solid") Repair the model with an STL editor, e.g. Scale, rotate and re-position (if necessary). Make the model manifolded with a flat bottom. Transform the model to a 3D model (digital elevation models usually are not 3D models). download a file, extract a square from given coordinate position This usually requires some extraction work, e.g. The outline of the workflow is the following (some tools allow combining steps, in some situations steps are done in different order or differently) Lake Geneva - Mont Blanc area - White PLA, 19x16.5cm, printed in 11h26m Read 3D printing of digital elevation models with QGIS An other powerful and versatile tool combination is using QGIS and the Demto3D plugin. Touch Terrain (see below), as of Mai 2021, is the best existing online service and it is totally free. The easiest solutions are Using Touch Terrain and Terrain2STL. So far, I identified several ways to create digital elevation models that work. For the moment, I just take down notes of what I am playing with. This text is under construction and may need re-organizing. Producing STL models from terrain data can be similar to producing models from 3D scans since some digital elevation models (DEMs) also use point clouds. 3D PRINT TERRAIN FILES HOW TO
This article describes how to create printable STL models with (mostly) free tools from various kinds of free terrain data (digital elevation models, DEM). Printed elevation models are useful in teaching, outreach activities, informal learning settings like museums, tourist offices, urban planning, etc. Milling is another option, but noisier and more dusty than 3D printing. For larger models we suggest stacking plates cut with a laser cutter or another tool. 3D printing is a good choice for smaller models. Physical terrain models can be made with various technologies.
