Hi all, I need to use the coordinates information contained in a kml file to write a wld file.
In the KML I have <LatLonBox> <north>47.551729</north> <south>45.438335</south> <east>12.736706</east> <west>9.670600</west> <rotation>-1.35</rotation> </LatLonBox> I converted them to UTM WGS84 32N coordinate system <LatLonBox> <north>5273247.79</north> <south>5031864.43</south> <east>781130.01</east> <west>552448.98</west> <rotation>-1.35</rotation> </LatLonBox> I calculated the resolution doing the differences between north/south and east/west and I get 251.441 and 238. To have squared pixel I would set to 250 (maybe it could be better to use 240?). with this info I created the wld file 250 -1.35 -1.35 250 552448.98 5273247.79 The reprojection works quite well, but it seems shifted by some pixels, does the procedure make sense or is completely wrong? PS With latlong values the image is located in a wrong place, but the wld seems correct, maybe the pixel value is wrong. 0.002201452083 -1.35 -1.35 -0.002201452083 9.670600 47.551729 -- ciao Luca www.lucadelu.org _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
