Editing Data

Two tools allow you to create, modify or delete elements on an editable layer. The JMap's Edition extension allows you to create new elements directly in cartographic interface, modify or delete them. The Element Explorer allows you modify attribut values of existing elements or delete existing elements.

Select the type of geometry you wish to create. Your selection must not be incompatible with the type of your personal layer (ex. you cannot  create polygons on a layer of points).

2

Select the layer on which you wish to create elements. If several editable layers have been added to the project (including personal layers), they will all appear in this list.

Note: The layer named Annotations is not a personal layer. It is a generic layer on which you can draw freely but it does not allow you to define attributes.

When you bring changes (add, modify, delete) to a personal layer, JMap stores the transactions that should be saved.

Press to save the layer transactions on the JMap server.

Press to reject the transactions and cancel all changes on the layer.

All editing operations can be canceled individually if they have not been saved. You can also restore canceled actions by clicking on the Redo arrow.
