Given a geoTIFF (a TIFF with floating point height field in channel 0), build a printable model.

The model is composed of a rectangular box whose top face is the relief map made from the TIFF height field.

• python 3
• see requirements.txt for python deps

Note: this tool needs an available GeoTIFF file to convert.

1. git clone this repo: git clone $THIS_REPO
2. cd $THIS_REPO
3. optional - make a virtual env for this repo: python -m venv .
4. install deps: pip install -r requirements.txt
5. python tiff2stl.py $GEOTIFF.tif $OUTPUT.stl

At the top of tiff2stl.py are several useful config options:

• HSCALE - the amount to scale the model in X/Y (east/west, north/south) (defaults to 50 since I'm using OS Terrain-50 data to test)
• VSCALE - the amount to scale the model in Z (elevation)
• BOXHEIGHT - the dimensions of the box under the model_
