- <p>This example show how a map can be serialized using OpenLayers Object Notation.
- The serialized map can be saved somewhere (like a cookie if it's under 4KB), and
- deserialized to restore the state of a map. Serializing features on a vector layer
- is possible, but creates a string that is typically too large for cookie storage</p>
- <p>Navigate to some location, turn layers on/off, click save state. Close this page
