I work with a lot of geospatial data, and I depend on a system installation of GDAL. GDAL lets me open geo-referenced TIF images, and it’s a dependency for a lot of python packages like Shapely and GeoPandas. If all I needed to do was use GDAL in python, I could try to install it through Anadona by running
conda install -c https://conda.anaconda.org/ioos geopandas=0.2.1
(note: this package was not compatible with python 3.6 when I tried it, so you might need to create a virtual environment with 3.5), but I also like to use some of GDAL’s command like tools like
gdal_pansharpen.py. So I had to suffer through a system-wide install for mac, which is a challenge.
