For transparency's sake, I posted this to gis.stackexchange (http://gis.stackexchange.com/questions/9609/translating-grid-to-usgs-dem-in-c-via-gdal), but haven't heard anything that really helps, so I thought this might be a better place to seek help.
I am attempting to translate ArcInfo binary grids to USGS DEM format (.dem) for input into VUE Infinite, a 3D visualization program. I am *very* new to GDAL, and I have installed the GDAL .NET bindings thru a (http://vbkto.dyndns.org/sdk/PackageList.aspx?file=release-1500-gdal-1-8-0-mapserver-5-6-6.zip) build installer. I can get to GDAL in my C# solution 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; String[] opts = new String[] { "PRODUCT=DEFAULT,ZRESOLUTION=float" }; Dataset dsDem = demDriver.Create("C:\\Data\\65587895\\foo.dem", x, y, 1, DataType.GDT_Int16, opts); 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 (http://www.gdal.org/formats_list.html) 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 DCAP_CREATE=YES, only DCAP_CREATECOPY=YES, which makes me cringe, thinking that indeed the GDALDriver::Create() method is not implemented for the USGSDEM format. I've also poked thought the source for the USGSDEM format, and don't see anything in there pertaining to creating a dem (although I could easily miss that, as I am by no means fluent in C++). Any thoughts or experience with this? Any other thoughts on translating ArcInfo binary grids (or anything for that matter) to DEMs? -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Translating-ArcInfo-binary-grid-to-USGS-dem-in-C-via-GDAL-tp6360189p6360189.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
