Frequently Asked Questions

Installation troubleshooting

Depending on pip version, installation problems can happen with packages dependencies installation order. Install and upgrade pip and numpy if demcompare installation crashes:

python3 -m pip install --upgrade pip
python3 -m pip install --upgrade numpy

Note

Be careful: Rasterio has its own embedded version of GDAL. Please use rasterio no-binary version in Makefile install if you want to use a GDAL local version:

python3 -m pip install --no-binary rasterio rasterio

Data Dimension Management

There are no constraints on the dimensions of input data, except that they must share a geographical footprint (cf: Intersection DEM schema). However, classification masks must have the same dimensions as the associated DEM. The constraints and returned error we impose are directly derived from the rasterio mask class .
