Interpolation: area vs. bilinear

by treble » Wed Aug 16, 2017 5:02 pm America/New_York

With l3mapgen there are three options for interpolation: nearest, bin and area.  Using gpt Mosaic the resampling options are nearest, bilinear and bicubic.

Is the equivalent of area in l3mapgen bilinear in Mosaic?

No.  But, there is an option called "fudge" which will increase the pixel/bin search size and return the average of the bins that intersect the "inflated" pixel size.
This will fill in holes if there are near enough the expese of effectively reducing resolution.  The next version will only apply the fudge if no matching bin for the requested pixel resolution is found...for now it does it to every pixel...this will better maintain the resolution.
