The items under Main menu > External Data allow the user to:
• To load, view and edit all ancillary data used by the model such as future development areas, informal areas, treasury fix areas, unit water demands and a digital terrain modelling (DTM) file. The data path to the ancillary data can be set via External Connections box (accessible via Model Data > Model Settings).
•Note that Cost data is listed in the External Connections box (can be regarded as ancillary data), but also has its own Cost Data menus, because of the many options and tables associated with this type of data.
