I am attempting to translate ArcInfo binary grids to USGS DEM format (.dem). I have installed the GDAL .NET bindings thru this build installer. I can get to GDAL in my C# add-in I am working on. However, it seems that I cannot create a USGS DEM:
Gdal.AllRegister(); GDAL.Dataset originalImage = Gdal.Open("C:\\65587895\\hdr.adf", GDAL.Access.GA_ReadOnly); Driver demDriver = Gdal.GetDriverByName("USGSDEM"); int x = originalImage.RasterXSize; int y = originalImage.RasterYSize; Dataset dsDem = demDriver.Create("C:\\Data\\65587895\\foo.dem", x, y, 1, DataType.GDT_Int16, null);
Gives the error:
System.ApplicationException: GDALDriver::Create() ... no create method implemented for this format.
I thought the USGSDEM format was read/write...am I wrong on that? The formats list says that creation of USGSDEM is supported, but a run of
demDriver.GetMetadata(null) to get the metadata from the USGSDEM driver results in no return of
DCAP_CREATECOPY=YES, which makes me cringe, thinking that indeed the
GDALDriver::Create() method is not implemented for the USGSDEM format.
Any thoughts or experience with this? Any other thoughts on translating binary grids to DEMs?
