Blue Marble has world edge gaps #94

Closed nvkelso closed 6 years ago

nvkelso commented 6 years ago

1 pixel gap on right, and 2 px gap on bottom of world

GDAL attempting to produce square pixels when not provided a target extent, lol Hard to get projected bounds of random CRS (coord ref system) Should either VRT or re-project Blue Marble to solve?

Fixed by using the VRT at s3://imagery-sources-tmp/blue-marble/200408.vrt, produced using:
