Hi everyone, I'm new to this list and would therefore like to say "hello and thanks for gdal" in the first place :-)
I just came across a minor problem where I would like to ask for your advice - the Global Landcover set GLC2000 is available in grid format from [0]. Associated with it is the .hdr file with the projection description [2]. Apparently the map units are in decimal degree. When I ask gdalinfo, I get the WKT description of the SRS, see [3] Everything's fine with this, I only came across the UNIT-Field UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9108"]], where the unit is degree, defined according to epsg:9108. When you look up epsg:9108 in the epsg registry [1] you get as Unit of Measure: Code: EPSG::9108 - Name: degree minute second hemisphere (i.e. not decimal degree) Shouldn't this rather be epsg:9102 then? Code: EPSG::9102 Name: degree, 1 degree: 0.017453292519943278 radian As I said, it's not very important, just out of curiousity. I'm using GDAL 1.7.0b2, FWTools 2.4.7, released 2010/01/19 Thanks a lot and kind regards, Chris ------------------------------------------------------------------------------------- [0] http://bioval.jrc.ec.europa.eu/products/glc2000/products.php [1] http://www.epsg-registry.org/ [2] glc2000_v1_1_projinfo.hdr: BANDS: 1 ROWS: 16353 COLS: 40320 INTERLEAVING: NA DATATYPE: U8 BYTE_ORDER: NA UL_X_COORDINATE: -180.000000 UL_Y_COORDINATE: 89.991071 LR_X_COORDINATE: 179.991070 LR_Y_COORDINATE: -56.008928 PIXEL_WIDTH: 0.0089285714 PIXEL_HEIGHT: 0.0089285714 MAP_UNITS: DD PROJECTION_NAME: Geographic (Lat/Lon) PROJECTION_ZONE: 0 PROJECTION_PARAMETERS: 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 SPHEROID_NAME: WGS 84 SEMI_MAJOR_AXIS: 6378137.000000 SEMI_MINOR_AXIS: 6356752.314245 E_SQUARED: 0.006694 RADIUS: 6371007.180918 [3] gdalinfo output: Driver: AIG/Arc/Info Binary Grid Files: glc2000_v1_1 glc2000_v1_1\dblbnd.adf glc2000_v1_1\hdr.adf glc2000_v1_1\log glc2000_v1_1\metadata.xml glc2000_v1_1\prj.adf glc2000_v1_1\sta.adf glc2000_v1_1\vat.adf glc2000_v1_1\w001001.adf glc2000_v1_1\w001001x.adf Size is 40320, 16353 Coordinate System is: GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], TOWGS84[0,0,0,0,0,0,0], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9108"]], AUTHORITY["EPSG","4326"]] Origin = (-180.004464285700010,89.995535666300043) Pixel Size = (0.008928571400000,-0.008928571400000) Corner Coordinates: Upper Left (-180.0044643, 89.9955357) (180d 0'16.07"W, 89d59'43.93"N) Lower Left (-180.0044643, -56.0133924) (180d 0'16.07"W, 56d 0'48.21"S) Upper Right ( 179.9955346, 89.9955357) (179d59'43.92"E, 89d59'43.93"N) Lower Right ( 179.9955346, -56.0133924) (179d59'43.92"E, 56d 0'48.21"S) Center ( -0.0044649, 16.9910716) ( 0d 0'16.07"W, 16d59'27.86"N) Band 1 Block=256x4 Type=Byte, ColorInterp=Palette Min=1.000 Max=23.000 NoData Value=255 Metadata: LAYER_TYPE=thematic Color Table (RGB with 256 entries) 0: 0,0,0,255 [..] _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
