 Hi All,

 I am encountering a gdalwarp issue that I have a hard time narrowing

 I have a Canadian DEM (CDED) in USGS DEM format in Lat/Lon NAD83 (EPSG
 4269) and I want to convert it to an ER Mapper ERS format in UTM Zone 16
 NAD27 (EPSG 26716).

 The command I use is the following:
 > gdalwarp -s_srs EPSG:4269 -t_srs EPSG:26716 -of ERS 042c_0100_deme.dem

 And the output is:
 > ERROR 1: No such file or directory
 > ERROR 1: GDALSuggestedWarpOutput() failed because the passed transformer

 GDAL was installed using osgeo4w.exe installer on my Window 7 machine.

 After doing some research it seems that datum shift grids may not be built
 by default with Proj.4.
 Is there other dependencies that may affect datum shifts?

 How can I check that datum shift grids were built and which ones?

 What can be an approach to add other datum shift grids?
