Hello, By using the following commands, it creates a raster which is opened and shown correctly in GIS software but it is displaid upside down in an image viewer or internet browser. ( gdalinfo gives Upper Right ( 11.0000000, 10.0000000) and Lower Right ( 11.0000000, 70.0000000) which shows image is upside down somehow )
Could you please help me to understand why ? I use GDAL_grid to convert a list of coordinates into a raster (interpolated). - VRT file I use is : <OGRVRTDataSource> <OGRVRTLayer name="lonlat"> <SrcDataSource>lonlat.csv</SrcDataSource> <GeometryType>wkbPoint</GeometryType> <GeometryField encoding="PointFromColumns" x="longitude" y="latitude" z="ssha"/> </OGRVRTLayer> </OGRVRTDataSource> - Command is : > gdal_grid -a invdist:power=3.0:smoothing=0.0: -zfield "ssha" -outsize 20 10 > -ot Int16 -a_srs EPSG:4326 -of GTiff -l lonlat lonlat.vrt A.tiff --config > GDAL_NUM_THREADS ALL_CPUS > gdalinfo A.tif Size is 20, 10 Coordinate System is: GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433], AUTHORITY["EPSG","4326"]] Origin = (-80.000000000000000,10.000000000000000) Pixel Size = (4.550000000000000,6.000000000000000) Metadata: AREA_OR_POINT=Area Image Structure Metadata: INTERLEAVE=BAND Corner Coordinates: Upper Left ( -80.0000000, 10.0000000) Lower Left ( -80.0000000, 70.0000000) Upper Right ( 11.0000000, 10.0000000) Lower Right ( 11.0000000, 70.0000000) Center ( -34.5000000, 40.0000000) _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
