GeoTIFF DEM als 3D-Modell (niam2026)

What this episode covers

Ich gebe einen kurzen Einblick, wie ich einen Open-Source-Workflow entwickelt habe, um das Copernicus-DEM für eine beliebige Region herunterzuladen und anschließend in ein 3D-druckbares Geländemodell zu konvertieren. Das [Copernicus DEM - Global and European Digital Elevation Model](https://dataspace.copernicus.eu/explore-data/data-collections/copernicus-contributing-missions/collections-description/COP-DEM) stellt weltweit ein Höhenmodell als GeoTIFF bereit, ich habe mich gefragt, wie ich für einen beliebigen Ausschnitt die GeoTIFFs herunterladen kann und basierend darauf das Höhenmodell als 3D-Modell drucken kann. Im Vortrag erkläre ich kurz meine Herangehensweise, die Auswahl der Technologien und wie ich die Skripte entwickelt habe. Der [Workflow ist open source](https://codeberg.org/stroebjo/dem-to-stl) und enthält folgende Schritte: - Download des DEMs von Copernicus mit dem HDA Client - GDAL basierte Shellskripte um die GeoTiffs zu mergen & croppen - Python Skript zum erstellen eines 3D-Modells - JavaScript Skript für ein Multimaterial 3MF file Licensed to the public under http://creativecommons.org/licenses/by/4.0 about this event: https://pretalx.news-infographics-analytics-maps.media/2026/talk/M3JKAY/
