# Raster styling methods Ellipsis Drive has made it easy to style your raster data :rainbow: {% embed url="" %} Just open a raster layer as show above and start using the styling methods described below :point\_down:

🟠 Channel-based styling (channelMap)

This method defines the color channels of the visualization based on the bands in the raster. For example, defining the Red Channel as Band 1, the Green Channel as Band 2 and the Blue Channel as Band 3. It's also possible to write free expressions using the bands, which creates a lot of freedom and flexibility to fine tune your visualisation.

🟠 Range-based styling (rangeMap)

This method maps an expression to a color depending on the range in which the value falls. The expression can simply be a band but also a custom expression, creating more freedom and flexibility to fine tune your visualisation. This can for example be used to create heat maps or intuitively visualize altitude.

🟠 Value-based styling (valueMap)

This method defines the visualisation based on an expression. The results of this expression are clipped to an integer and assigned a color. This can for example be used for raster data that contains classifications. Each class corresponds with a number, which can be assigned a color.

🟠 Condition-based styling (caseMap)

This method assigns colors based on conditions. These condations can be defined with free expressions for full flexiblity.
