ARD UTM-to-Albers Cloud Shadow Placement Shift Between Projections

This image displays areas that indicate differences cloud shadow placement shifts when processed in UTM, vs. Albers. Left side: false color image and pixel quality assessment panes for a Landsat scene (path 15/row 35) in the Albers Equal Area Conic projection. Right side: the same products for the same scene in the Universal Transverse Mercator (UTM) Zone 18N projection.

In the pixel QA images purple and brown represent clouds, beige represents cloud shadows, and cyan represents clear land. The yellow ellipsoid is an example of a region in the scene where the known cloud shadow placement shift between two projections appears.
