Complexity: Medium


When using gdalwarp to reproject from epsg:4326 to epsg:4269 and compare with result from WCPS (it is different in any projection). The origins (bounding box) of Rasql is different to gdalwarp.

Here is the comparison of gdalwarp and Rasql


using gdalwarp

gdalwarp -t_srs 'epsg:4269' -r bilinear -of GTIFF test.tif test_3.tif

WCPS query

for c in (test_projection) return encode(crsTransform(c, 
{ Lat:"http://www.opengis.net/def/crs/EPSG/0/4269", 
 Long:"http://www.opengis.net/def/crs/EPSG/0/4269"}, {}), "tiff")

also data to import if one want to reproduce

  • Milestone changed from 9.2 to 9.3
  • Resolution set to fixed
  • Status changed from new to closed

with current WCPS and rasql, it returns the same bounding box, the only difference is the pixel size but it is small (e.g: -91.773493181419440 and -91.773493181429174), see the difference here https://www.diffchecker.com/m4jnpipv, close ticket.
