Map data can come in various forms depending on the real world objects it is representing. In their most basic form they can be just images eg. Aerial Photos or scanned Historic maps; BUT they can also come as intelligent maps where various geometric shapes (from points to lines or areas) store additional information specific to the individual objects depicted. The power of these intelligent maps emerges in systems such as CityStreAtZ which enable them to be combined and interrogated.
The map data used by the Council falls into two basic categories:
- Externally sourced base maps (for instance, Ordnance Survey 'Mastermap') or images (for instance, historic maps and aerial photos)
- Internally created maps relating to various diverse functions (eg Planning; Highways; Education; Housing) which can be overlaid on to the base maps for locational context
