May 08, 2012 -- Getmapping has added the OS MasterMap® Imagery Layer by Ordnance Survey, to its data offering. Customers can now order offline, select and download image files via the webshop or stream the imagery direct to their CAD or GIS applications via WMS. Getmapping customers now have unrivalled options when it comes to imagery and can choose between Getmapping and Ordnance Survey data of Britain.
OS MasterMap Imagery Layer comprises of aerial images which have been edge matched together to create seamless coverage of Great Britain. The images have been orthorectified, so that the features in the other OS MasterMap layers align well with their counterparts in the Imagery Layer. The images have been captured under specific conditions to minimise the effects of shadow and cloud. Every image is colour balanced together with adjacent images and carefully edge matched to minimise any differences caused by variations in atmospheric conditions at time of capture. Rigorous quality checks ensure that the layer maintains a consistent standard of both positional accuracy and image quality.
Ordnance Survey’s aerial imagery is complimented by the 250 surveyors it deploys on the ground. This helps Ordnance survey to make more than 5,000 updates to its maps every day. OS MasterMap is one of the most up-to-date mapping products available. Taken together with Getmapping’s own update program the choice of imagery in terms of currency, resolution and delivery options is hard to beat.
“Now our customers have unprecedented choice when it comes to imagery,” said Dave Horner, Managing Director of Getmapping. “For the professional user our data provides the highest level of detail but in some areas the OS MasterMap® Imagery Layer may be more recent and may provide the best choice, data currency being critical to many clients. For those wishing to use a WMS feed Getmapping offers a fully maintained and updated data stream for all its imagery products so customers can be certain that they have access to the most up data,” continued Horner.
