The cartosky package provides a astronomically oriented interface to ploting sky maps based on matplotlib.basemap. This package addresses several issues present in the healpy plotting routines:
healpysupports a limited set of sky projections (cartview,mollview, andgnomview)healpyconverts sparse healpix maps to full maps to plot; this is memory intensive for largenside
In addition, cartosky provides some convenience functionality for large optical surveys.
The best way to install cartosky is if you have anaconda installed. If you have trouble, check out the .travis.yml file. The procedure below will create a conda environment and pip install cartosky:
conda create -n cartosky numpy scipy pandas matplotlib cartopy astropy ephem healpy nose -c conda-forge
source activate cartosky
pip install cartosky
If you want the bleeding edge of cartosky, you can follow the directions above to create the conda environment, but then install by cloning directly from github:
git clone https://github.com/kadrlica/cartosky.git
cd cartosky
python setup.py install
