GIS data can be stored in various ways as files at the operating system level or within a number of different database systems. Each of these has a number of restrictions and there are practical issues that occur when maintaining the data. See the Corporate Standards for Spatial Data.
It is important to plan the relationship with our geographic data and GIS when considering systems that may have a geographic element.
For example the ability to use backgound mapping from our spatial database.
See the Requirements for the procurement of systems with mapping/GIS functionality.
The new Webmaps Extra Highways viewer (AGOL) will be replacing both its previous and current versions (Highways
Webmap-extra and old Webmaps Extra Highways) whilst also providing many of the most useful features within
the Highways Map Explorer. However, the current Webmap Extra Highways will run simultaneously with the new
viewer for a while so as to ease staffs into the new viewer. For more information on the new viewer please see the
User Guide .
The old Viewer is in the process of being decommissioned (due to using technology that is now out of support).
Where possible please use the new one imediately below. This is faster and clearer and contains current information.
Quickstart Guide .
The new viewer provides most, but not all, of the functionality of the old one;
a solution to this is in progress and users will be updated accordingly.
In the meantime, the old viewer is still available for those who need it. Please be aware however that information and mapping is not being maintained.
