Steve,
First, you may not be aware that gdal_translate writes TIFF by default,
even if you use the extension .img. So if you want a .img output you
would need to specify -of HFA on the commandline.
The warning indicates that there was too much metadata in the source
file to properly store in the GeoTIFF so it was discarded. Often
this won't matter to you.
When I launch this command
gdal_rasterize -burn 0 -i -l rssMtl_32198
Z:\MSSS\rssmrn\2005\shapefile\32198\rssMtl_32198.shp rssMtl.img
I get this message
Warning : the output raster dataset has a SRS, but the input vector
layer not. Results will be probably incorrect.
0...10...20...30...40...50...60...70...80...90...100 - done.
This means it is your responsibility to ensure that the shapefile
and the .img file are in the same coordinate system since the command
cannot determine it from the .shp file. The warning is perhaps a bit
too dramatic.
Best regards,
