gdal_grid geotransformation matrix

[peifer]

Line 1000 of gdal_grid.cpp defines:
adfGeoTransform[3] = dfYMin; I guess this should be:
adfGeoTransform[3] = dfYMax;

I should probably mention that the starting point for the bug report was the observation that -tye ymin ymax leads to corner coordinates with swapped y-values (1), whereas -tye ymax ymin leads to the expected corner coordinates (2).

(1)

gdal_grid -txe 5.5 15.5 -tye 47 55.5 ...

Corner Coordinates:
Upper Left  (   5.5000000,  47.0000000) 
Lower Left  (   5.5000000,  55.5000000) 
Upper Right (  15.5000000,  47.0000000) 
Lower Right (  15.5000000,  55.5000000) 

(2)

gdal_grid -txe 5.5 15.5 -tye 55.5 47 ...

Corner Coordinates:
Upper Left  (   5.5000000,  55.5000000) 
Lower Left  (   5.5000000,  47.0000000) 
Upper Right (  15.5000000,  55.5000000) 
Lower Right (  15.5000000,  47.0000000)

I'd note that the current registration of gdal_grid output is consistant with the order of the rows (the first to appear are the southern ones), but yes, it is unusual. I have also been tempted in the past to change it into something more usual ("north-up" image). CC'ing Andrey if he can mention if the current behaviour is accidental or intended.
