Hi Everybody, I am trying to display HDF files using MapServer, and upto some extent i have done it. Still i am facing problem with the projection of map.
and MapFile Layer looks like this: LAYER NAME wise_io #DATA 'o.tif' DATA 'HDF5:"C:/ms4w/apps/HDFData/data/output.h5"://Mapped_-_Composited_mapped' DUMP TRUE TYPE RASTER STATUS ON CLASSITEM "[pixel]" CLASS EXPRESSION ([pixel] > 0) STYLE COLOR 0 0 255 END END PROJECTION {{{{ ................ }}}} END END and GDAL INFO for used HDF data is : ....................... Driver: HDF5Image/HDF5 Dataset Files: none associated Size is 3630, 2530 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"]] Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0, 2530.0) Upper Right ( 3630.0, 0.0) Lower Right ( 3630.0, 2530.0) Center ( 1815.0, 1265.0) Band 1 Block=3630x1 Type=Float32, ColorInterp=Undefined Metadata: Mapped - Composited mapped:Projection Category=IDL Mapped - Composited mapped:Projection Name=Cylindrical Mapped - Composited mapped:Source=A2010021053000_CHL.L2_LAC Mapped - Composited mapped:units=mg m^-3 Mapped - Composited mapped:Slope=1.000000 Mapped - Composited mapped:Intercept=0.000000 Mapped - Composited mapped:Scaling=linear Mapped - Composited mapped:Limit=4 62 27 95 Mapped - Composited mapped:Projection ID=8 Mapped - Composited mapped:Latitude Center=0 Mapped - Composited mapped:Longitude Center=78.5 Mapped - Composited mapped:Isotropic=1 Mapped - Composited mapped:Rotation=0 Mapped - Composited mapped:Position=0 0 1 1 Mapped - Composited mapped:Scale=0 Mapped - Composited mapped:Central_Azimuth=0 Mapped - Composited mapped:HDF4_OBJECT_TYPE=SDS Mapped - Composited mapped:HDF4_OBJECT_NAME=Mapped - Composited mapped Mapped - Composited mapped:HDF4_REF_NUM=2d .............................................................................. I have created the GeoTiff using gdal_translate and projected it and it works well. >> gdal_translate -ot Byte -of GTiff -b 1 -a_ullr 62 4 95 27 >> HDF5:"output.h5"://Mapped_-_Composited_mapped o.tif. I am facing problem with projection of HDF data set which is 1 KM gridded dataset. and as without defining Projection Derivative it is showing somewhere else in the map. can anyone help me in this regard to define Projection section of HDF data layer. with regards Venkat _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
