Raster styling methods | Ellipsis Drive

Raster data can contain one or more bands where each band has its own significance. The RGB method is used to assign different raster bands to Red, Green, Blue channels to create an image visible to the human eye.

The RGB method has the following parameters

1️⃣ Band Bias - This parameter allows you to add a value on top of the existing band value to enhance the intensity of color.

Band Value + Band Bias = New Band Value

2️⃣ Band Weight - This option allows you to multiply the band value on top of the existing value.

(Band Value + Band Bias) * Band Weight = New Band Value

Band bias and Band weight are ways to adjust the color intensity, enabling you to make red more red, green more green, etc.

The Band to color method allows you to choose one raster band and connect its defined values to a specific color. The band to color method has the following color functions.

Fade - This option allows you to assign a color of your choice to a specific band value.

Exact Color - This option allows you to assign a color of your choice to a range of band values.

📌 The Hillshade method produces a grayscale representation of the surface, with the sun's position taken into account for shading the image.

The surface area that faces the sun will be represented light in color and the surface area hidden from the light will be represented as dark in color.

The method has a parameter called angle that can be used to change the sun's position.

This method is used to convert two raster bands into a vector field.

The first raster band will be used for magnitude in the X-direction. The second for magnitude in the Y-direction.

With this method, you can type a formula to perform the desired band algebra.

The value calculated by the formula will be mapped to a color.

NOTE: You can only use the operations "+", "-", "*", "/" and "^". You can refer to the bands using the following variables band1, band2, ...,band3

This method allows you to map a specific integer value to a color.

With this option, you can use over 1000 classes.
