Global Mapper Masterclass: DEM to 3D Contours & KMZ Export

Learn how to generate precise 3D contour lines from any Digital Elevation Model (SRTM DEM) using Global Mapper, configure custom contour intervals, and export 3D contours directly into Google Earth Pro & AutoCAD! In this tutorial, we cover: ✅ Loading project vector alignment / KML boundaries ✅ Streaming 1-arc-second SRTM Worldwide Elevation DEM data ✅ Configuring custom contour intervals (0.5m, 1m, 2m, 5m) as per your project slope ✅ Enabling contour smoothing & automatic elevation unit labeling ('m') ✅ Inspecting real-world terrain using the Slope Shader & Feature Info tool ✅ Exporting 3D contours to .KMZ with full elevation Z-attributes ✅ Verifying 3D contour draping over high-resolution satellite imagery in Google Earth Pro ⏱️ Timestamps / Chapters: 0:00 - Introduction & Project Alignment Loading 0:17 - Streaming SRTM 1-Arc-Second DEM Data 0:39 - Elevation Range & Terrain Boundary Setup 1:02 - Contour Generation Options & Custom Intervals 1:29 - 0.5m Contour Rendering & Slope Shader Visualization 1:52 - Feature Info Tool: Querying 3D Elevation Coordinates 2:24 - Exporting 3D Contours to Google Earth (.KMZ) 2:41 - Google Earth Pro 3D Contour Draping & Verification 2:50 - Channel Outro & Next Steps 📌 Recommended for Civil Engineers, Surveyors, GIS Analysts, and Hydrologists working on road alignments, drainage design, and flood modeling. 🔔 Subscribe to Hydrology Atlas for more in-depth engineering software masterclasses! #GlobalMapper #GIS #CivilEngineering #Contours #DEM #Hydrology #Surveying #GoogleEarthPro #AutoCADCivil3D
