The settlement file is an update to an dataset orinally called "Urban Areas" (created in 1991).
All boundaries have been digitised against master-map (1:1250) at a scale of 1:500. Each boundary should be at a distict master map edge.
In most cases the line has been "re-digitised" by changing the position of the boundary edge from the 2007 settlement file (itself) using the ARCGIS Map Topology tools.
Each existing settlement was checked using the Settlement Boundary Rules. By using the Map Topology toolset it meant that boundaries that were meant to be coincident
(for example Baldock and Letchworth) could really become so. At the same time,
the whole process was made faster by the ability to trace along the MasterMap lines themselves.
At the start of the digitising process it had been decided not to include the allotments. These were then added by highlighting where they were on the edge of a settlement
and the boundaries re-digitised.
The names of the settlements were checked to ensure they were unique. Where not the highest administrative area's name was added in brackets - i.e. district or civil parish;
"Church End (Little Hadham CP)", "Church End (Stocking Pelham CP)" and "Church End (Three Rivers)".
The settlement file was cliped to the 1:10,000 Ordnance Survey BoundaryLine for Hertfordshire County.
Finally, the population of each settlement was estimated. This used the most recent residential AddressPoint file for the county (2009-12) and the 2007 Mid-Year Population Figures.
