I'm trying to use gdalwarp to reproject an ascii grid file. According to http://www.gdal.org/formats_list.html this shouldn't be a problem and indeed I can happily use gdal_translate to create grd files (AAIGrid) but not gdalwarp:
gdaltest 14:40:08 $ gdal_translate -of AAIGrid rj_DEM_1978.grd junk.grd Input file size is 401, 301 0...10...20...30...40...50...60...70...80...90...100 - done. gdaltest 14:40:25 $ rm junk.* gdaltest 14:40:41 $ gdalwarp -of AAIGrid rj_DEM_1978.grd junk.grd Output driver `AAIGrid' not recognised or does not support direct output file creation. The following format drivers are configured and support direct output: VRT: Virtual Raster GTiff: GeoTIFF NITF: National Imagery Transmission Format HFA: Erdas Imagine Images (.img) ELAS: ELAS MEM: In Memory Raster FITS: Flexible Image Transport System BMP: MS Windows Device Independent Bitmap PCIDSK: PCIDSK Database File ILWIS: ILWIS Raster Map SGI: SGI Image File Format 1.0 Leveller: Leveller heightfield Terragen: Terragen heightfield netCDF: Network Common Data Format HDF4Image: HDF4 Dataset ISIS2: USGS Astrogeology ISIS cube (Version 2) ERS: ERMapper .ers Labelled RMF: Raster Matrix Format RST: Idrisi Raster A.1 INGR: Intergraph Raster GSBG: Golden Software Binary Grid (.grd) GS7BG: Golden Software 7 Binary Grid (.grd) PNM: Portable Pixmap Format (netpbm) ENVI: ENVI .hdr Labelled EHdr: ESRI .hdr Labelled PAux: PCI .aux Labelled MFF: Vexcel MFF Raster MFF2: Vexcel MFF2 (HKV) Raster BT: VTP .bt (Binary Terrain) 1.3 Format LAN: Erdas .LAN/.GIS IDA: Image Data and Analysis GTX: NOAA Vertical Datum .GTX NTv2: NTv2 Datum Grid Shift CTable2: CTable2 Datum Grid Shift ADRG: ARC Digitized Raster Graphics SAGA: SAGA GIS Binary Grid (.sdat) gdaltest 14:40:52 $ which gdal_translate /Library/Frameworks/GDAL.framework/Programs/gdal_translate gdaltest 14:41:05 $ which gdalwarp /Library/Frameworks/GDAL.framework/Programs/gdalwarp gdaltest 14:41:10 $
As you can see, the format list is somewhat shorter than normal. From the two
which commands at the bottom you can also see that both
gdal_translateare located in the same library.
Does anyone have an explanation for this? I can work around it easily enough but this shouldn't be happening, should it?
