You may not like the symbology used in this map.. but you can’t deny that the “Interactive map of England’s green belt” published by the Telegraph Newspaper yesterday is an another important milestone in the opening up of Government Geodata.
It is important for a number of reasons..
Firstly it liberates data that was previously difficult/expensive to obtain from the Department for Communities and Local Government both displaying it on a Google Map, but also making it available for download as a shape file for use by others – Kudos !
Secondly and rather parochial I accept, it is an example of data that was based on Ordnance Survey mapping published on the web.. not exactly case law but a good precedent supporting the view that a feature must exist as an object in the original OS data for it to be derived !
Thirdly and I would argue of most importance is that this data is really useful.. it is timely as it helps to inform the current debate around the planning system, and it is of real interest to citizens who can easily view areas protected by the planning system close to their homes !
Seems that there is healthy competition in data journalism !
