Placemarks

Spatial Placemarks are geographic locations that you can define and access later. They provide a quick way to move the view in your Image window between a set of "places" that you need to revisit frequently. Placemarks are saved with the session information when you save and restore views and layers.

To create and use placemarks, you need a view that contains layers with map information.

Create a Placemark

A new placemark is defined by the area visible in your active view, including location, scale (zoom level) and rotation.

1. Select Placemarks > Add Placemark from the menu bar. The New Placemark dialog appears.
2. Enter a name for the placemark, or use the default name.
3. Click OK. The placemark is added to the Placemarks menu, where you can select and go to it as needed.

To go to a saved placemark, select Placemarks > placemark name from the menu bar. The view moves to the defined location, including the zoom level and any rotation that was applied to the view before the placemark was saved.
