1.I use GDAL to read a DEM file,and its extension is .img ,what other extensions for DEM file?
2.When I reand a geotff file and a dem file,I find that the dfference between them as follows:
GetDriver()->GetDescription() : GTiff, HFA
GetDriver()->GetMetadatItem(GDAL_DMD_LONGNAME): GeoTIFF Drdas Imagine Images(.img)
bandnumber 6 1
Now,I want to know that,the bandnumber of DEM file is always 1?
