Maps and scenes have properties that determine many aspects of their operations, appearance, and functionality. In ArcGIS Pro, the map's name is an example of a map property.
You control the properties of a map from the Map Properties dialog box. For example, when you create a map or scene, you can accept its default name or you can specify a new name on the General tab.
The Map Properties dialog box is organized into tabs. The properties you can set for maps may be unavailable for scenes, and vice versa. For example, you can only define the elevation units for scenes.
The layers in the map or scene have their own set of properties separate from the map properties.
Map Properties dialog box
You can view and change the properties of maps and scenes from the Map Properties dialog box. From the Contents pane, right-click the map or scene and click Properties 
to open it. From any tab, click Apply to preview the changes, or click OK to apply all changes and close the dialog box.
The properties are arranged in tabs on this dialog box, as follows:
- General—Use this tab to make adjustments to the basic properties of a map or scene.
- Name—The name of the map or scene.
- Map units—The map units of the map or scene. This setting is defined by the coordinate system.
- Display units—The display units of the map or scene's view. This setting is displayed at the bottom of the view.
- Elevation units—In scenes, the units of the viewing height relative to the ground.
- Reference scale—The base reference scale for all features drawn in the map.
- Rotation—The orientation (in degrees) of the map. You can choose an option from the menu or enter a custom angle. The origin is 0° (cardinal east). Positive values rotate the map counter-clockwise (arithmetic).
- Background color—The color of the map's background. Select a color from a style, or define a custom color.
- A choice to turn masking on or off for the whole map or scene.
- A choice to include the maximum scale in drawing ranges in maps and local scenes.
- A choice to assign unique IDs when sharing web layers.
- Extent—The map's extent is the area covered by the data on your map. You can define and set the custom extent for the map or scene. By default, the map uses the extent of the data from all layers.
- Clip Layers—Use this tab to clip the map or local scene's layers to an outline (in maps only) or a custom extent. By default, no clipping is applied.
- Metadata—Use this tab to record additional information about your map or scene, such as map credits, description, and terms of use. See View and edit metadata for more information.
- Coordinate Systems—Use this tab to define and set the map's geographic or projected coordinate system. Scenes allow you to set a vertical coordinate system. You can also create a custom coordinate system based on the map or scene's region of interest. By default, the coordinate system is determined by the first dataset you add to the map or scene.
- Transformation—Use this tab to define how transformations reconcile datum conflicts with the map or scene's coordinate system and its layers. You can also create and store additional transformations with the map for later use.
- Illumination—Use this tab to set how scenes simulate sunlight, shading, shadows, and illumination definitions. Illumination only applies to maps with TIN layers.
- Labels—Use this tab to define global label parameters for maps. These options are unavailable in scenes.
- Color Management—Use this tab to change the color model and color profile your map or scene uses to display color. This is often used to assist in color matching across devices and in printing workflows.
