Dennis,
You can create a new raster with the pixel values scaled to one bit so that
all you have is zero for no color and one for any color. Use gdal_translate
with the -scale option. The exact method depends on the data. Then you are
essentially ignoring the color.
Contours are set as lines inst
I have been using the GDAL utilities. But ran into a snag. We create
KML overlay files, basically KML file that geolocates a PNG on google
maps. This PNG is a vector image as well as can have 1 or two colors
other than the transparent background.We used gdal to convert this
to a GEOTIFF usin
