Ordnance Survey has two data capture programmes running in Scotland. Continuous revision programme is to data capture the most importance topographic change to the majority of customers’ needs – mainly build development.
OS aims to capture these features within six months of construction being completed on the ground. Almost 30,000 continuous improvement jobs have been created in Scotland within last 3 years.
Urban geospatial content improvement programme has the objective to capture or update of physical features that reflect construction, demolition or other alterations in the real world.
These changes may be to geometry or attribution (for example: new construction or demolition, addition or removal of traffic signs that impact on routing applications, change to the function being undertaken at a site like vacant area of hardstanding now used as a public car park).
The outcome is delivery of content improvement to existing data or capture of additional information that did not meet the previous data capture specification.
