[GRASS-user] Importing From GeoPDF

If you have 3 red, green, blue channels, you can combine them to display using d.rgb (under the special raster menu button in the layer manager) or combine them into a single color map using r.composite.

Hello,

I'm trying to import a new-style GeoPDF USGS topo map into an existing GRASS location as a raster layer.  I've converted the file to a GeoTIFF with gdal_translate and then adjusted to projection using gdalwarp.  When I import the GeoTIFF into GRASS, each color band is written as a separate layer:
r.in.gdal input=/Users/dkindem/MI_Grand_Haven_20110923_TM_geo_wgs.tif output=MI_Grand_Haven_20110923_TM_geo_wgs
Projection of input dataset and current location appear to match
r.in.gdal complete. Raster map <MI_Grand_Haven_20110923_TM_geo_wgs.red> created.
r.in.gdal complete. Raster map <MI_Grand_Haven_20110923_TM_geo_wgs.green> created.
r.in.gdal complete. Raster map <MI_Grand_Haven_20110923_TM_geo_wgs.blue> created.
(Sun Aug 19 10:50:07 2012) Command finished (2 sec)

Each layer displays (in monochrome), but I'd like to create a single, color, layer.

I'm curious to know if others have encountered this, or have thoughts on the issue.

Thanks in advance,

Dave
