Hi I try to load a NITF with multidataset into ArcGIS Desktop . But ArcGIS tells me that there is no spatial reference in my file. Then I check with gdalinfo which tells me that my file is referenced with WGS84.
Then I try to convert the file with gdal in GeoTiff format I'm using gdal 1.9.2 and try to convert a NITF with multidataset into a GeoTiFF file. I'm using ns3361c.tif downloaded from http://www.gwg.nga.mil/ntb/baseline/software/testfile/Nitfv2_1/scen_2_1.htmlas a sample. I try : gdalwarp NITF_IM:0:ns3361nc.nsf test.tif gdalwarp NITF_IM:1:ns3361nc.nsf test.tif gdalwarp NITF_IM:2:ns3361nc.nsf test.tif gdalwarp NITF_IM:3:ns3361nc.nsf test.tif the online doc of gdalwarp explains : Mosaicing into an existing output file is supported if the output file already exists. but the result test.tif doesn't conains all subdataset. Thanks in advance. xlhomme
