HowTo use the Plugin Edition

First, you have to log in since only authorised users have access to the edition options.

You can only edit one layer at a time. In the demo, there are three different editable layers, one for each type of geometry. Select the layer to edit in the dropdown menu.

Polygon

Selecting a Polygon

  • Click on the icon.

  • Click on the polygon to select.

You can also click-and-drag to select all polygons within an area.

Selected polygons attribute values will appear below the map.

You will probably notice the radio-button and the zoom-like icon on the right of the table.

If you have several polygons selected, the radio-button will allow you to activate a polygon so that you can edit its features on the map (move or delete the polygon, move, add or remove vertex). The selected polygon is hilighted in on the map.

You can even navigate while editing. For example, you can zoom in to edit more precisely.

Edit the information of an existing polygon

  • Select a polygon.
  • Edit the values in the table.
  • Click on the Validate button to save the new values.

Creating a New Polygon

  • Click on the icon.

  • Click on the map to draw each vertex of your polygon.
  • To close your polygon, double-click with the mouse left button, or click on the first vertex of the polygon.

To have two polygons totally side by side, check the Vertex Snapping checkbox (magnet icon). This is useful to prevent extra spacing between consecutive polygons.

  • First, select the existing polygon beside which you will create a new one, using the select tool.
  • When you start creating a new polygon next to an existing polygon, click on the first polygon vertex along the matching side, the new polygon vertex will be positionned exactly over the existing polygon vertex.
  • Click on the Validate button to save the new polygone.

Deleting a Polygon

To delete a polygon, you need to have at least one selected polygon. See section "Selecting a polygon".

  • Once you have a selected polygone, click on the icon.

  • Now click on the polygon you want to delete, to activate it. Click a second time to trigger the deletion.
  • A warning will be displayed to confirm the deletion. If you select "ok", you will notice that the polygon table entries have been struck.

  • Click on the Validate button to delete the polygone and all related information from the database.

If you click on the Cancel button, all the modifications not validated are canceled.

Moving a Polygon

To move a polygon, you need to have at least one selected polygon. See section "Selecting a polygon".

  • Click on the icon.

  • Click on the polygon you want to move to activate it.
  • Click and drag to the new position.
  • Click on the Validate button to definitively set the polygon position.

Editing a Polygon Vertex

To edit a polygon vertex, you need to have at least one selected polygone. See section "Selecting a polygon".

  • Moving a Vertex
    • Select the icon.

    • Click on the polygone to activate it.
    • Click and drag the vertex you want to move.

  • Adding a Vertex
    • Select the icon.

    • Click on the polygon to activate it.
    • Click precisely over the spline (border) where you want to have the new vertex.

  • Deleting a Vertex
    • Select the icon.

    • Click on the polygon to activate it.
    • Click on the vertex to delete.

  • Validate!

You can combine the move, add and delete vertex actions before validating. Click on the Validate button to validate the polygon vertex modifications.

Cancel

If you need to cancel drawings or to get back to a classic navigation, click on the cancel button.

Lines and Points

Lines and Points editions are similar to polygon edition.
