Using Vertex Tools¶
Vertex tools are tools that modify the shape of existing geometries by adding/removing or deleting vertices from geometries. The partial exception is the hole cutting tool, which can create and edit holes in polygons.
The following tools feature vertex editing:
Notes on working with vertex tools:
- Vertexes are represented by a small square, which can be selected with a single click. Depending on how zoomed out you are a single vertex may represent many points in your original dataset.
- The vertex will change shape during editing, as an example when creating a polygon the original starting point will grow larger as you close the polygon to provide feedback that snapping will be performed.
- When editing animated circles are used to indicate any snapping that occurs; this provides a visual indicate of where you clicked and where the vertex was relocated to due to snapping
- When deleting a vertex visual feedback is also provided
- If any additional feedback is required it will be offered in the middle of your map as a “pop up bubble” allowing you to fix the problem without losing your place.
- many of the tools support the use of the scroll wheel to change zoom level while editing; and the middle mouse button to support panning
