#1199 closed defect (wontfix)

[raster] ST_AsRaster problem with scale being < 1.

Reported by: Bborie Park Owned by: Bborie Park
Priority: medium Milestone: PostGIS 2.0.0
Component: raster Version: master
Keywords: Cc:

Description

The following fails to properly burn the specified value to the generated raster. If both scales are ≥ 1, there are no problems. Need to see how gdal_rasterize utility works around the problem.

SELECT ST_Value(ST_AsRaster(ST_MakePoint(0, 0), 0.1, 0.1), 1, 1);
SELECT ST_Value(ST_AsRaster(ST_MakeLine(ARRAY[
	ST_MakePoint(0, 0),
	ST_MakePoint(1, 0)
]), 0.1, 0.1), 1, 1);

Resolution: wontfix
Status: newclosed

Can't fix as testing identical geometries with PostGIS and gdal_rasterize showed that the behavior displayed in PostGIS matched that of gdal_rasterize. Might be a gdal bug?

Further testing after upgrading GDAL to trunk r23097 showed that this problem resolved itself with the latest revision.
