Define areas of interest

Available with Aviation Charting license.

You can set the extent of your aeronautical charts by defining an area of interest (AOI). An AOI contains information about your chart such as the type of chart, spatial reference, rotation, and reference scale. You can have multiple areas of interest depending on the scope of your data. Areas of interest are configurable, are defined by tags, and can be grouped together using the MapID field.

Create an AOI

You must create at least one polygon feature within the AOI feature class before you can make an aeronautical chart. The AOI feature class is located inside of an AIS geodatabase.

1. Start ArcGIS Pro.
2. Open or create a new project containing aviation data.
3. Complete the following steps if your project does not contain an AOI feature layer:
   1. If necessary, click View > Catalog Pane to display the Catalog pane.
   2. Click the Databases drop-down arrow to expand the folder.
   3. Click the drop-down arrow next to your AIS geodatabase and right-click the AOI feature class.
   4. Click Add To Current Map.

      The AOI feature class appears in the Contents pane as a feature layer.

4. Click Edit > Create.

   The Create Features pane appears.

5. Click AOI.
6. Optionally, change the editing tool by clicking one of the following buttons:

   

7. Create features on the map using the chosen editing tool.
8. On the Edit tab, in the Manage Edits group, click Save.

Configure areas of interest

The AOI feature class in the AIS geodatabase schema contains attributes for defining multiple areas of interest. You can define an AOI by a unique map ID, a spatial reference, tags, reference scale, and rotation. You can configure these attributes to define your areas of interest.

1. Click the Edit tab.
2. Click Select and click the AOI feature you want to configure on the map to select it.
3. Right-click the selected feature and click Attributes.

   The Attributes pane appears.

4. Change the following values in the Attributes section:
   1. Type a unique value in the MapID field.

      Note:

      Map ID values have a specific syntax. These values follow the pattern <Parent>::<Child>. For example, a valid Map ID is AERONAUTICAL::VISUAL::ANC::SANFRAN. This relationship between parent and child allows you to organize your areas of interest across large data sets.

   2. Type a double floating point value in the ReferenceScale field.

      For example, the input value 500,000 sets the reference scale for the AOI to 1:500,000.

   3. Type a double floating point value in the Rotation field.

      For example, the input value 90 rotates the map extent by 90 degrees.

   4. Choose a value from the UseGeographicExtent drop-down menu.
      • Yes—The AOI uses geographic extent.
      • No—The AOI does not use geographic extent.
   5. Optionally, click the Update Spatial Reference button and choose a projected coordinate system for the SpatialReference field.
   6. Type unique tags in the Tag text box.

      Note:

      Tags must be separated with a semicolon.

5. Click Apply.

   Your AOI configuration is saved to the AOI feature layer. You can view information about the active AOI by clicking Charting, and clicking AOI Information.

6. On the Edit tab, in the Manage Edits group, click Save.
