The Geographic Editor shows a geographic representation of the catchment model, and displays the sub-catchment map and the node-link network of the current scenario.

Several commands are available when you right-click in the Geographic Editor (Figure 1):

| When deleting nodes and links, there is no warning given, and no confirmation is sought. When a node is deleted, all links immediately upstream or downstream of the node are deleted as well. This action cannot be undone |

| Note: Sub-catchment runoff is fed into links, so deleting the receiving link, that is, the link associated with the sub-catchment, effectively stops that catchment runoff from entering the system. When this happens, the sub-catchment boundary is highlighted in red to indicate that it is disconnected from the network. |
To reconnect a disconnected sub-catchment to the network:
- Create a new node (if necessary) and add a link to act as the receiving link for the sub-catchment;
- Choose Select from the contextual menu and click the catchment you wish to reconnect;
- Right-click and choose Attach Link (this will contain a sub-menu listing links that do not have a sub-catchment inflow); and
- Select the desired link to attach the sub-catchment to the link.
Geolocation coordinates and elevations for nodes and reaches can be set using Location Control.
