3.10.4.2 Applying Style for a GeoRaster Layer

You can style a GeoRaster map layer using the following steps.

The instructions assume that you have a GeoRaster map layer displayed on your Active Project page.

1. Click against the dataset in the Data tab of the Layers list.
2. Select Settings in the context menu.
   The Layer Settings panel opens.
3. Optionally, modify any of the following options in the Style:
   • Opacity
   • Maximum Brightness
   • Minimum Brightness
   • Saturation
   • Contrast
   • Hue Rotate
   • Fade Duration
4. Optionally, modify any of the following rendering options in the Raster tab:
   • Bands: Spatial Studio, by default supports the following bands:
     • Red
     • Blue
     • Green
     • Alpha

     For GeoRaster images that have more than three layers, you can choose which three layers you want to visualize.

   • Reprojection: represents the interpolation method to be used when transforming an image from one SRS (Spatial Reference System) to another.
   • Image Processing: represents the subprogram to be used to enhance the visual quality of the images.
   • Rendering Hints: represents the image interpolation value that determines how each image cell's value on a view port is interpolated using the original image pixels. For example:
     • NEAREST NEIGHBOR: This option has no interpolation by taking the nearest image pixel's value directly.
     • BI-LINEAR: This option will consider 4 neighboring pixels to determine the image cell's value on a view port.

     Additionally, you can also switch on or off the Transparent NODATA toggle, which determines if the image cells are to be transparent or not. If the switch is on, then the layers underneath will be visible for areas that have NODATA in the image.

   The GeoRaster map layer is rendered with the updated settings.
