generate-hypsometric Command

Usage

Color Ramps

Examples

Standard Tinting
Shades Of Gray Tinting
Tinting And Shading

Generates a hypsometric tinting image.

Usage

generate-hypsometric [parameters]

All parameters are optional:

bounds: optionally specifies the exact geometry bounds of the area to generate the hypsometric tinting. If this parameter is not specified, the current map view bounds will be used (or if geometry bounds are set, these boundaries will be used).
ramps: specifies color ramps to use for the tinting. If not specified, the default ramps will be used.
sample-rate: a real value greater than or equal to 1 which represents the sample rate to use when fetching original DEM data. Use value larger than the default 1 if the map area is very big, this will descre

Color Ramps

ramps parameter lets you specify your own hypsometric tinting scheme. This is done by defining key elevation points and their associated colors, for example:

elevation of 0 meters should be represented by a green color
elevation of 1000 meters should be represented by a light brown color
elevation of 2000 meters should be represented by the white color.

Then you specify these in the parameter:

ramps=0:green;1000:#FFCB77;2000:white

As you can see, the format of the parameter is

elevation1:color1;elevation:color2;...;elevationN:colorN

Examples

Standard Tinting

 generate-hypsometric

Generates the hypsometric tinting using the default values.

Shades Of Gray Tinting

 generate-hypsometric ramps=300:white;1500:black

Generates the hypsometric tinting so that everything below the elevation of 300 meters is colored in pure white, while the elevation of 1500 meters and above is in pure black. Everything in between is a shade of gray.

Tinting And Shading

You can mix hypsometric tinting with hillshading methods like generate-relief-igor Command:
