Add a site mask to export directory #89

Open ircwaves opened 8 years ago

ircwaves commented 8 years ago

For each polygon that produces a gips_export stack, a common use case is analyzing the pixels within the polygon. As NoData pixels within the polygon cannot be differentiated from NoData pixels outside the polygon, a "site mask" needs to be added to each directory that is created by gips when exporting imagery.

This should be done in a manner that will generate a binary raster that will sit exactly on the same spatial grid as the images in the gips export. This likely means using gippy.algorithms.CookieCutter.

Did you determine if the gips_project landsat --res 30 30 ... site masks differ based on their source imagery's projection?
