dsm2dtm VS rasterio

Github repo

Github repo A python tool that generates DTM (Digital Terrain Model) from DSM (Digital Surface Model).

Indeed it works. I din't even had to change any parameters. Almost identical to groundtruth DTM (Lidar derived). Here is the link - https://github.com/seedlit/dsm2dtm/blob/main/results/example2_dsm2dtm_hillside.png

TiTiler is a dynamic tile server built on FastAPI and Rasterio/GDAL. Its main features include support for Cloud Optimized GeoTIFF(COG), multiple projection methods, various output formats (JPEG, JP2, PNG, WEBP, GTIFF, NumpyTile), WMTS, and virtual mosaic. It also provides Lambda and ECS deployment environments using AWS CDK.

You're missing transform headers etc, you can write it out with GDAL but rasterio is generally easier to use than the Python GDAL bindings, here's an example.

Out of curiosity, what's stopping you from keeping the data in GTiff and just sampling from them with coordinates? Lots of free software lets you do that easily (e.g. QGIS, rasterio if you use Python etc). Am I not seeing something here?

I, for one, read the docs. May fortune smile on those who put effort into https://rasterio.readthedocs.io/

They are terse, but enough breadcrumbs to fumble my way to a working input for gdal_proximity.py

Possibly I'm not a representative sample, but one of my mantras at the office is "If you ain't doc'in', you ain't rockin'."

(Though we are only doing ransom note wiki pages, not library documentation.)

If the package doesn't have shiny Sphynx docs, at least afford us a few cryptic utterances in the source code.

Looks like rio (Rasterio CLI) also uses gdal libraries. https://github.com/rasterio/rasterio/blob/master/rasterio/rio/clip.py
