I am trying to grid a set of points. My input is a CSV file for which I have created a VRT file. The input coordinate system is WGS84 but the output is Transverse Mercator (for which I have an ESRI PRJ file). The command completes but the output is upside down. Here is the command line.
gdal_grid.exe -ot Float32 -of GTiff -a_srs "a10tm.prj" -txe 134498.3 865501.7 -tye 5425283.9 6659287.2 -outsize 73 123 -a invdist:nodata=9999 -l alberta_out "alberta_out.vrt" "abl_val_16.tif" Here is the console output. Grid data type is "Float32" Grid size = (73 123). Corner coordinates = (129491.408618 6664303.466297)-(870508.591382 5420267.656599). Grid cell size = (10013.745713 10032.546852). Source point count = 835. Algorithm name: "invdist". Options are "power=2.000000:smoothing=0.000000:radius1=0.000000:radius2=0.000000 :angle=0.000000:max_points=0:min_points=0:nodata=9999.000000" 0...10...20...30...40...50...60...70...80...90...100 - done. An output image is created but upside down. The top should be the bottom and vice versa. Any ideas? If so, please respond to this email address. Thanks. =========================== David V.
