Camp Susque (Trout Run, PA) Elevation Model by malbert

Last crawled date: 3 years ago

The 46002160PAN tile from the 3.2 ft DEM from PASDA. Tiles from the LiDAR survey are 10,000 ft square. This 3D model is natively 127mm (aka 5") square. Area around Camp Susque, including Rattlesnake Mountain and Lookout Mountain.

My process for creating STL:
-Import GeoTIFF DEM into QGIS (http://www.qgis.org/)
-Convert to rendered GeoTIFF (see this tutorial http://maps.cga.harvard.edu/qgis/wkshop/export_GeoTiff.php)
-Import into Blender as plane (http://www.blender.org)
-Subdivide Plane several times (W)
-Apply sub-surface division modifier
-Apply GeoTIFF texture as Displacement modifier (use Extend image mapping)
-Add 1.0 Mean Crease to perimeter edges
-Apply sub-surface division then displacement modifiers to mesh
-Scale mesh object based on map size / height
-Edit mesh, select all, extrude down in Z
-Scale lower mesh to flat plane (S, Z, 0)
-Export as STL
-Done!
