#599 closed defect (fixed)

imagecrsmetadata when subsetting near border

Reported by: pcampalani Owned by: mdumitru
Priority: major Milestone: Future
Component: petascope Version: development
Keywords: imagecrsmetadata border Cc:
Complexity: Medium


I currently can reproduce the error only on a coverage I imported here locally.
I will take care of this.

The problem arise on an imagecrsdomain expression, where the coverage is previously subset near its border.

for c in (eobscov_higher)
return imagecrsdomain( c[Long(30:50)] , Lat)

This ticket is hard to reproduce as it depends on data of coverage to calculate sdom based on ImageCrsDomain?. I have tried to make a coverage same coordinates (Lat, Long, time) as you but actually the query can return value. It is pity that you could not attach the file for testing later then I think this ticket will be closed if no one reports a same error.

Hi Pham,
Yes, sorry I left this behind. !
I guess you can close this ticket, it might have been fixed along with some other patch. !
