And browse the documentation (with rendered examples) and README on its website:
- OpenTopography (also has 3DEP/LIDAR data): https://portal.opentopography.org/datasetMetadata?otCollecti...
- SRTM 30M tile tool: https://dwtkns.com/srtm30m/
I also second the "rite of passage to fight with GDAL" sentiment :)
I'd also recommend Robert Simmon's introduction to GDAL for stitching, etc:
And that video looks like a great resource--I'll put it on my watch list.
Maybe title should be "making 3d maps with satellite imagery and 3d maps" ;)
I was searching around and found something noting they won a contract to build the Army's One World Terrain 3d model. This OWT appears to be some kind of classification for applying sat imagery over terrain data sets, maybe?
One thing also for readers is that https://dwtkns.com/srtm30m requires an account with https://urs.earthdata.nasa.gov to download tiles.
If so, it seems like you could fly a drone with two cameras at relatively low altitude and get insane resolution for things like cityscapes at a pretty low cost
EDIT: Meant to add that your webpage discussion was great & thanks for sharing!
I also provide instructions in my (free and open source!) masterclass on how to take LIDAR data from cities and build 3D surface models that includes buildings:
