We recently completed a mapping project for the town of Corby in Northamptonshire. The objective of this project was to map and name all the roads of Corby and the surrounding area.
All the roads were initially captured in the People's Map. A GIS survey team then travelled to Corby to field check the accuracy of the road data created in People’s Map. Since Corby has developed quite rapidly over the last few years, the survey team found that the aerial imagery (2006) was not up to date enough to capture all the roads so embarked on a GPS survey of these roads. As part of this field check and survey exercise, all the road positions and attributes where checked and verified.
The 1st image below shows the raw GIS data in blue that was captured in People’s Map from the 2006 Aerial Imagery as source and the GPS surveyed data in red, overlaid on a snapshot of the existing PM extent. This red GPS surveyed data is not yet visible in People’s Map as yet, but is sceduled to be imported into the online version in the near future.

The 2nd image shows a graphically modified road map of Corby. This data will now be used by our client to create a final map, including various layers like railways, parks, etc.
The People’s Map is proud to say, due to the extent of this data capture project, we currently hold the most up to date map of Corby that exists.
