Shows the use of the WFS Transactions (WFS-T).
Parks of Osnabruck (Frida).
Base layers is OpenStreetMap from Omniscale WMS Server.
The WFS protocol allows for creation of new features and reading, updating, or deleting of existing features.
Use the tools to create, modify, and delete (in order from left to right) features. Use the save tool (picture of a disk) to save your changes. Use the navigation tool (hand) to stop editing and use the mouse for map navigation.
See the wfs-protocol-transactions.js source to see how this is done.
