darker, you could use COLOR_INTENSITY=7. (NOTE: This parameter has been deprecated in favor
of the COLOR_INTENSITY_FULL parameter).
• COLOR_INTENSITY_FULL (elevation and raster only) - specifies the color intensity to use when
adjusting the brightness of pixels in the overlay. Valid values range from 0 to 512, with 0 being
completely white, 256 being no alteration, and 512 being completely black. For example, to make an
image slightly darker, you could use COLOR_INTENSITY=300. (NOTE: This parameter replaces
the COLOR_INTENSITY parameter).
• TEXTURE_MAP (raster only) - specifies that this image should be draped over any elevation data
loaded before it. Use TEXTURE_MAP=YES to turn on. Anything else turns it off.
• TRANSPARENT_COLOR (elevation and raster only) - specifies the color to make transparent when
rendering this overlay. The color should be specified as RGB(,,). For example,
to make white the transparent color, use TRANSPARENT_COLOR=RGB(255,255,255). If you do
not wish any color to be transparent, do not use this parameter. Optionally, if the image that you are
making transparent uses a palette for the colors, you can specify a palette index in the following
format: INDEX(). For example, to make the second color in the palette
transparent, use TRANSPARENT_COLOR=INDEX(1).
• TRANSPARENT_COLOR_DIST - for layers that have specified a color to make transparent, this
parameter allows you to specify how far a color in the layer has to be from the specified
TRANSPARENT_COLOR value to be treated as transparent as well. The default value of 0 means
that the colors have to exactly match for the pixel to be treated as transparent. Larger values (up to
256) allow larger distances between the layer color and the transparent color. This is useful for lossy
formats, like JPEG.
• COLOR_GRADE (raster only) - specifies the color grading values to use for this layer (as configured
on the Color Grade options dialog tab). This should be a comma-delimited list with the saturation
value (from 0-1) first, then the input and output range for the red, green, and blue color channels, as
follows:
COLOR_GRADE=saturation,red_in_start,red_in_end,red_out_start,red_out_end,...,blue_out_end
• PROJ_NAME - specifies the name of the projection to use for this file (this will override any
projection information stored in the file). This name must have been defined with a prior
DEFINE_PROJ command.
• PROJ_FILENAME - specifies the name of the projection (.prj) file to use for this file (this will
override any projection information stored in the file).
• PROJ_EPSG_CODE - specifies the numeric EPSG projection code that defines the projection for this
file (this will override any projection information stored in the file). For example, use
PROJ_EPSG_CODE=26715 to define a UTM zone 15 projection with NAD27 as the datum and
meters as the units.
• PROMPT_IF_PROJ_UNKNOWN - set to NO if you don't want the user to be prompted to select a
projection if the projection of the file cannot be automatically determined.
• ELEV_UNITS - specify elevation units to use for this file if it contains gridded elevation data and
also for vector feature elevations that don't have a unit embedded in the elevation value. Valid values
are as follows:
♦ FEET - export in US feet
♦ DECIFEET - export in 10ths of US feet
♦ METERS - export in meters
♦ DECIMETERS - export in 10ths of meters
♦ CENTIMETERS - export in centimeters
• ELEV_OFFSET (elevation only) - specifies the offset in meters to apply to each elevation value in the
layer. This allows you to vertically shift a layer to match other layers.
• ELEV_SCALE (elevation only) - specifies the scale value to apply to each elevation value in the
layer. This allows you to vertically scale a layer to match other layers. Default to 1.0 (no scaling).
