Focus on Quality
Ordnance Survey has invested considerable resources and worked closely with its imagery suppliers to provide orthorectified imagery that achieves the consistently high quality expected by our customers.
Unlike other data sources, such as topographic data, imagery can be very subjective. It is difficult to quantify specific tolerances for atmospheric conditions, such as haze. We ensure our suppliers adhere to a detailed set of quality levels for the key aspects of imagery with an emphasis on data quality over image appearance alone. For instance priority is given to ensuring detail such as road markings can be seen within shadows and to positional accuracy.
OS MasterMap Imagery is fully orthorectified to provide a high level 1.1m RMSE (Root Mean Squared Error) accuracy and correct alignment with other detailed OS data products.
OS MasterMap Imagery uses the same source imagery that underpins data updates for other large-scale OS products. More than 97% of OS MasterMap Imagery is less than five years old; 90% is less than three years old. Contact us to check imagery currency for your area of interest.
Each OS MasterMap Imagery tile is accompanied by a separate XML metadata file in a consistent format across every image in the layer. The metadata is extremely detailed and includes information ranging from imagery capture date to photographic lens focal length.
