Hi all, I am trying to convert an Arc/Info binary grid raster file to a shapefile using the gdal_polygonize.py utility. But the operation fails with the following error
*Warning 1: Unsupported Arc/Info Binary Grid tile of type 0x80 encountered. This and subsequent unsupported tile types set to no data value.* Here is a screenshot of the error http://osgeo-org.1560.n6.nabble.com/file/n4373658/Capture1.png I am able to open and view the binary grid file just fine in ArcMAP etc. Here are the results when i run gdalinfo on the binary grid file. It seems to be fine Driver: AIG/Arc/Info Binary Grid Files: /home/vish/Sample_Data/nh_priority /home/vish/Sample_Data/nh_priority.ovr /home/vish/Sample_Data/nh_priority/vat.adf /home/vish/Sample_Data/nh_priority/w001001x.adf /home/vish/Sample_Data/nh_priority/w001001.adf /home/vish/Sample_Data/nh_priority/hdr.adf /home/vish/Sample_Data/nh_priority/dblbnd.adf /home/vish/Sample_Data/nh_priority/prj.adf /home/vish/Sample_Data/nh_priority/sta.adf Size is 4987, 9645 Coordinate System is: PROJCS["NAD83 / New Hampshire", GEOGCS["NAD83", DATUM["North_American_Datum_1983", SPHEROID["GRS 1980",6378137,298.257222101, AUTHORITY["EPSG","7019"]], AUTHORITY["EPSG","6269"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.01745329251994328, AUTHORITY["EPSG","9122"]], AUTHORITY["EPSG","4269"]], UNIT["METERS",1], PROJECTION["Transverse_Mercator"], PARAMETER["latitude_of_origin",42.5], PARAMETER["central_meridian",-71.66666666666667], PARAMETER["scale_factor",0.999966667], PARAMETER["false_easting",300000], PARAMETER["false_northing",0], AUTHORITY["EPSG","32110"], AXIS["X",EAST], AXIS["Y",NORTH]] Origin = (228040.838957945175935,311318.187724410032388) Pixel Size = (30.000000000000000,-30.000000000000000) Corner Coordinates: Upper Left ( 228040.839, 311318.188) ( 72d35'2.81"W, 45d17'53.85"N) Lower Left ( 228040.839, 21968.188) ( 72d32'41.44"W, 42d41'39.84"N) Upper Right ( 377650.839, 311318.188) ( 70d40'35.98"W, 45d17'51.67"N) Lower Right ( 377650.839, 21968.188) ( 70d43'8.53"W, 42d41'37.85"N) Center ( 302845.839, 166643.188) ( 71d37'52.26"W, 44d 0'0.06"N) Band 1 Block=256x16 Type=Byte, ColorInterp=Palette Min=0.000 Max=2.000 NoData Value=255 Overviews: 2494x4823, 1247x2412, 624x1206, 312x603, 156x302 Color Table (RGB with 3 entries) 0: 255,255,255,255 1: 211,255,190,255 2: 0,84,3,255 <GDALRasterAttributeTable> <FieldDefn index="0"> <Name>VALUE</Name> <Type>0</Type> <Usage>5</Usage> </FieldDefn> <FieldDefn index="1"> <Name>COUNT</Name> <Type>0</Type> <Usage>1</Usage> </FieldDefn> <FieldDefn index="2"> <Name>STEW_STATUS</Name> <Type>2</Type> <Usage>0</Usage> </FieldDefn> <Row index="0"> <F>0</F> <F>7209043</F> <F>non-eligible</F> </Row> <Row index="1"> <F>1</F> <F>7672024</F> <F>eligible, non-priority</F> </Row> <Row index="2"> <F>2</F> <F>11779591</F> <F>priority</F> </Row> </GDALRasterAttributeTable> -- View this message in context: http://osgeo-org.1560.n6.nabble.com/gdal-polygonize-error-with-Arc-Info-binary-grid-tp4373940p4373940.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
