00006: Layer's symbology is not supported
Your map layer is using an unsupported map symbology option. The symbology option is not supported because the symbology type can affect drawing performance.
- Change your map layer to use a supported symbology option for display.
- Alternatively, remove the map layer that uses an unsupported symbology option.
The layer's symbology option defines how each map layer portrays a dataset in the map display. When you create a map layer in ArcMap, you have options for specifying how the information in your layer will be portrayed. This is sometimes referred to as a map renderer.
For example, when displaying polygons, you can fill them with colors, patterns, or icons. You can draw the polygon boundaries using various line symbols or use cartographic representations to apply special effects. You can draw charts within each polygon or use dot density fills, and much more.
Many of these portrayals use advanced symbology that is cartographically complex and requires more time to generate a map display. Hence, not all symbology options are supported for basemap layers and optimized map services. Many of the unsupported, advanced symbology options are used to show quantities or values for features.
Here is a list of map renderers that are not supported for basemap layers and optimized map services:
- Quantify by Category
- Dot Density
Alternatively, you can redefine the map layer to use simpler map symbology that will provide higher performance. The following lists outline symbology options that are supported for feature layers and raster layers:
Supported symbology options for features
- Unique Values
- Classes Using Graduated Colors
- Classes Using Graduated Symbols
- Classes Using Proportional Symbols
- Cartographic Representation
Supported symbology options for raster data
- Unique Values
- Colormap—Use the Colormap symbology option as you would the Unique Values symbology option or when you want the values in the raster layer to be represented by a prespecified color. The Colormap symbology option appears automatically in the list of available symbology options on the Symbology tab.
- Discrete Color—Use Discrete Color when you want to display the values in the raster dataset using a random color. This symbology option is similar to the Unique Values option, but it is more efficient when there are a large number of unique values as it does not have to calculate how many unique values exist. The Discrete Color option will assign a color to each unique value until it reaches the maximum number of colors that you chose. The next unique value will start at the beginning of the color scheme; this process will continue until each unique value has a color assigned to it.
You can find alternative ways of expressing quantities in statistical maps. For example, for more information about feature displays, see About symbolizing data to represent quantity where you can read about using color or graduated symbols to show quantity.
For more information on raster display, see Renderers used to display raster data.
