Dynamic color correction #71

Closed mojodna closed 6 years ago

mojodna commented 7 years ago

Required for raw Landsat 8 imagery, facilitates runtime changes to color profiles for individual source images - based on metadata, heuristics, + capabilities provided by sat-utils / landsat-util and rio-color.

Done using percentiles.py, which extracts values at 2nd, 5th, 95th, and 98th percentile for use as { values: { <band>: { min: <min>, max: <max> } } }.

This implements simplistic rescaling of values to within the desired range rather than more advanced color correction.

This is working good enough to close. Followup work is probably needed, but let's open new tickets around specific problems.
