[mapserver-users] Gdal for esri .hdr labelled .bil raw raster

[Claude Philipona]

I'm trying to use Mapserver 3.5 with gdal:
MapScript Version (Aug 1, 2001)
MapServer version 3.5 (pre-alpha) OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS INPUT=EPPL7 INPUT=JPEG INPUT=OGR
INPUT=GDAL INPUT=SHAPEFILE

I know that gdal is working, because I'm able to resample .tif rasters on the fly
into new projections.

I would like to use some ESRI .hdr Labelled .bil raw raster file via gdal (to
read GTopo 30 data). According to gdal doc, this format is supported and to open
a dataset  the file with the image file (often with the extension .bil) has to be
selected.

I could have it worked. I get this error:
Fatal error: MapServer Error in msDrawRaster(): Unrecognized or unsupported image
format.

I have a file named "alps.bil" (raw raster) and "alps.hdr" in the data folder.

Here is part of the .map file

LAYER
  NAME "alps"
  DATA "alps.bil"
  TYPE RASTER

  STATUS ON

  PROJECTION
     "proj=latlong"
     "ellps=clrk66"
  END

END


Here is the .hdr file:

file_title               = alps
data_type                = raster
grid_cell_registration   = center
map_projection           = Lat/Lon
left_map_x               = 2.00000000000
right_map_x              = 18.00000000000
upper_map_y              = 52.00000000000
lower_map_y              = 43.00000000000
number_of_rows           = 1080
number_of_columns        = 1920
grid_size                = 0.00833333333
elev_m_unit              = meters
min__value               = -16
max__value               = 4570
elev_m_min               = -16
elev_m_max               = 4570
elev_m_missing_flag      = -500
number_of_display_colors = 256
data_value_unit          = elev_m
data_byte_order          = little_endian


Any idea how to have this work, and , more generally how to use gdal to open
format supported only by this extension?

Thanks
