Style polygon layers

You can create custom visualizations in your scenes by applying smart mapping styles to your data. With polygon feature layers, you can choose styles that use attributes to apply continuous colors or individual colors, or styles that apply a single color to all the polygons.

2D Polygon

Use the 2D Polygon style when you want to apply a single color to the polygons in your scene. You can mark the project areas in a city with a unique fill and outline color to make the projects stand out in your scene, for example.

1. Follow the steps in the Style layers workflow.
2. For Color, click the color picker for pattern, fill, and outline options.
   1. Expand Pattern.

      Click a pattern to apply to the polygons or select the solid box for no pattern.

   2. Expand Fill and click the Enable fill toggle button to turn the fill color on and off.

      The following fill color options are available:

      • Colors displays general colors from which you can choose.
      • Custom color allows you to create a custom color. You can copy the Hex, RGB, and HSV values. Under Saved, apply saved colors, which you can add or remove.
      • Fill transparency allows you to set the fill transparency with the slider or by entering values.
   3. Expand Outline and click the Enable outline toggle button to turn the outline color on and off.

      The following outline color options are available:

      • Colors displays general colors from which you can choose.
      • Custom color allows you to create a custom color. You can copy the Hex, RGB, and HSV values. Under Saved, apply saved colors, which you can add or remove.
      • Outline transparency allows you to set the outline transparency using the slider or by entering values.
      • Stroke allows you to apply the outline width using the slider or by entering values.
3. For Elevation Mode, see Elevation mode.
4. For Labels, see Apply labels.

3D Extrusion

Use the 3D Extrusion style when you want to symbolize polygons with an extrusion in real-world dimensions in a single color. You can build a city from a set of building footprints extruded by a height attribute or manually enter a constant height for all the buildings.

1. Follow the steps in the Style layers workflow.
2. For Color, click the color picker:
   • Colors displays general colors from which you can choose.
   • Custom color allows you to create a custom color. You can copy the Hex, RGB, and HSV values. Under Saved, apply saved colors, which you can add or remove.
   • Fill transparency allows you to set the fill transparency with the slider or by entering values.
3. For Height, click the drop-down menu to change the height of the extruded polygons.
   1. Choose an attribute from the drop-down menu to give the polygons height. Select <Fixed value> to manually enter a uniform size.
   2. Choose the measurement unit from the drop-down menu.
   3. As you zoom in and out, click the Fit to view button to adjust the extrusion height to be appropriately sized in the current view.
4. For Elevation Mode, see Elevation mode.
5. For Labels, see Apply labels.
6. For Edges, see Visualize edges.

Water

Use the Water style when you want to symbolize water polygon features, such as lakes, oceans, rivers, or pools. You can display an ocean with realistic wave animation and colors, for example.

1. Follow the steps in the Style layers workflow.
2. For Type, choose from the following visualizations to add levels of detail to water features:
   • Oceans and seas
   • Lakes and rivers
   • Pools

3. For Color, click the color picker:
   • Colors displays general colors from which you can choose.
   • Custom color allows you to create a custom color. You can copy the Hex, RGB, and HSV values. Under Saved, apply saved colors, which you can add or remove.
   • Fill transparency allows you to set the fill transparency with the slider or by entering values.
4. For Waves, change the size of the waves by moving the slider from Small to Large.
5. For Direction, choose the direction of the waves in relation to the compass direction.
   • The value is the number of degrees the wave direction is offset going clockwise from the compass direction. You can enter a value or use the arrows to change the value. Leave the field blank for no wave direction.
   • Click the Change direction to next 45° interval button or press Enter or Spacebar to change the direction to the next 45-degree interval.

2D Types

Use the 2D Types style to apply individual colors to polygons based on either text or numeric attributes. For example, you can display the zoning areas in a city by color based on zoning type, such as Commercial, Residential, or Industrial.

1. Follow the steps in the Style layers workflow.

   The 2D Types pane appears with the Mapped Attribute box displaying the specified attribute.

2. Modify the Attribute Values list.

   The most common attribute values are listed. The remaining attribute values are automatically grouped into the Other section. By default, the attribute values are listed in descending order by the number of features, which is listed next to each attribute. The total number of features is displayed at the top of the list.

   1. Click an attribute value to modify.

      Do any of the following:

      • Change the symbology.
      • Drag the attribute value to change the order in the list and in the legend.

Change elevation mode

You can change the elevation mode to customize the positioning of your layers. Click the Elevation Mode drop-down arrow . Options that determine the vertical positioning of the layer and its data appear.

On the ground	Drapes the layer onto the ground.
Relative to ground	Positions the data aligned to the ground elevation. Z-values are added to the ground elevation when available.
Relative to scene	Positions the data aligned on top of 3D object scene layers and integrated mesh scene layers, depending on which has a higher elevation. If the graphic is not directly above a 3D object or any other feature, it is aligned to the terrain surface elevation. Note: If present, the geometry's z-value is added to the elevation.
Absolute height	Positions the data vertically based on the feature’s geometry z-value position. If the geometry doesn’t contain z-values, the default elevation is sea level.
<custom>	Positions the data vertically based on a custom elevation defined in the layer, such as from an attribute expression. The <custom> option is only visible when the layer has custom elevation.
Offset	Applies a positive or negative integer value in meters to vertically offset the elevation based on the specified Elevation Mode. Relative to ground—The layer is aligned to the ground and is vertically offset from the ground based on a height value entered. Relative to scene—The layer is aligned to the top of the scene layer and is vertically offset from the scene layer based on a height value entered. Absolute height—The layer is aligned to the z-value position assigned or defaults to the sea level position, and is vertically offset based on a height value entered. Note: Offset is not available for On the ground elevation mode.

Apply labels

If labels are available in your layer, you will see a Labels toggle button. By showing labels in your scene, you can immediately convey information about the scene based on an attribute in the layer.

1. Click the Labels toggle button to turn labels on and off in your layer.
2. You can configure the labels by doing any of the following:
   • For Text, click the drop-down menu to choose the attribute for labeling. You can select <custom> when custom label expressions are saved from another app, such as Map Viewer Classic.
   • For Size, choose small, medium, or large for the label size.
   • For Color, you can make your text either light or dark.
   • For Callout size, choose an appropriate scale (city, regional, world) and length (small or large) for the callout lines. Scale affects how long you can see the callout lines when zooming out.
     • Select <none> for no callouts.
     • You can select <custom> when custom callout lines are saved from another app, such as ArcGIS Pro.
   • Click the Improve perspective toggle button to display labels more intuitively, so labels that are farther away are smaller.

Visualize edges

For 3D polygon styles, click the Edges toggle key to accentuate and stylize the edges and outlines of the extruded polygons.

To use Edges, do the following:

1. Click the Edges toggle key to turn edges on and off.
2. For Style, choose the style of the lines defining your edges.
   • solid—Solid straight line.
   • sketch—Hand-drawn sketched line.
   • <custom>—Custom-styled line only available when saved from another app, such as ArcGIS Pro.

     Note:

     If <custom> is selected, the Color and Size options are unavailable.

3. For Color, choose either light or dark for the edge lines.
4. For Size, choose thin, standard, or thick for the thickness of your lines.

Caution:

It is not recommended to use the Edges option when you have polygon layers with a large number of features.
