Raster layers can be set up to support multiple defined symbology items. Each of these symbology items will display the raster layer with a predefined set of symbology parameters. This means you don’t need to redefine the symbology each time you use a different variable (on the Multidimensional tab) or apply a processing template (on the Data tab). You can also set up multiple symbology items for a regular raster layer so that it can also have multiple predefined items.
A raster layer may contain a data source of multiple variables such as a layer created from a netCDF file or a data source with multiple templates such as a .crf file. These variables or templates often require different types of default symbology.
Once you preconfigure a symbology item, you can register it, which applies specific symbology parameters for a specific variable, template, or renderer for the layer. These settings are saved in a layer file (.lyrx) that can be shared and used by others with similar raster datasets; however, this layer file will contain more than one set of predefined symbology parameters.
Complete the following steps to create a raster layer with multiple symbology items:
- Set the symbology.
If you are using multidimensional data or a raster function template, ensure that you are on the proper variable or template.
- Register the symbology items.
- Manage the symbology items if necessary by editing existing symbology sets or adding another symbology set to the raster layer.
- Save the multiple symbology items in a layer file.
- Use the raster layer with all the symbology items.
Once the symbology items have been registered and saved in a layer file, you can use the symbology items from the Symbology drop-down list—as if it was another primary symbology type.
You can share and import this layer file (.lyrx) with raster datasets and raster layers that are similar.
