A Python package for for georeferencing and orthorectifying hyperspectral imagery
Project description
gref4hsi
The hyperspectral toolchain is a toolbox for the georeferencing and orthorectification of hyperspectral pushbroom data. It was made with a special emphasis on georeferencing and co-registration of underwater hyperspectral data. However, it is equally simple to use for airborne data.
Installation instructions:
Set up a virtual environment with python 3.8. The following has been confirmed to work with anaconda virtual environment with python=3.8 on a windows 10, dell precision

For remaining dependencies, run: pip install -r requirements.txt
A *.bat script was added for automated installation and testing.
The pyvista function multi_ray_trace depends on the pyembree install and should be tested with /test/test_multi_ray_trace.py. For my machine the test takes 0.35 s. If it does not work, consider installing pyembree with anaconda (for mac and linux): conda install -c conda-forge pyembree
