This package provides a convenient Julia interface for loading spatial test data. It is based on the TestImages package but provides spatial datasets.
Full documentation and description of the datasets available in SpatialTestData.jl can be found here.
Just like all unregistered Julia packages, you can use Pkg to install it:
pkg> add https://github.com/felixcremer/SpatialTestData.jl # hit ] to enter Pkg mode
using SpatialTestData
img = testimage("s1_jurua_singlelake_large.nc") # fullname
img = testimage("s1_jurua_singlelake_large") # without extension works
Test data will be automatically downloaded into artifact folders when you load the dataset for the first time.
A detailed guide on contributing to SpatialTestData.jl can be found in the documentation mentioned above.
