Undoing your drawing progress if you make a mistake

Snapping

Snapping to the layer you're editing

You can snap to other objects in the same layer by enabling snapping. Click the magnet icon then 'This Layer'.


Snapping to OS MasterMap

If you have access to OS MasterMap in your account then you'll also be able to choose "OS MasterMap" from the snap menu.


When selecting this option the screen will populate with yellow lines and points. These represent the OS MasterMap nodes that you can snap to.



Please note: only those with a PSGA licence or OS MasterMap licence will be able to see this option.

When drawing with snapping enabled, you can snap to individual nodes, or anywhere along a line.



Please note: Snapping to OS MasterMap is only available below 1:1,250 scale. So if you notice the yellow nodes have disappeared, that's why.

Geo-positioning

As well as adding points to the map using your cursor or touch-screen, you can also utilise your mobile devices' GPS position. With geolocation enabled (Using Geolocation (GPS Positioning) you can press this button to place a point where your current position is.


Bear in mind that the accuracy of your device may not give you a perfect position.


Removing specific nodes from an object

You can remove specific nodes from an object by clicking the 'Remove Vertex' icon in the Feature Editor then clicking on the nodes along a line or on the perimeter of a polygon.
