#4193 closed defect (wontfix)

Geolocation transformer backmap unsuitible for modis swath

Reported by: winkey Owned by: warmerdam
Priority: normal Milestone: closed_because_of_github_migration
Component: default Version: unspecified
Severity: normal Keywords:


The backmap generated from modis swath data has a saw-toothed shape towords the left and right edges of the image due to verlap between modis strips.

One thought is to detect the overlap and exclude the overlaped pixels from the second strip.

something like this patch, but the warped result is still rather low res on a 250m swath file, I think that is a unrelated issue.

Without this fix the transformer fails many times when using gdalwarp without a -te switch.
