Number of surveys, buildings and places edited
This graph gives a measure of the maintenance activity on the NPOR and shows the number of surveys, buildings and places which have been edited during each month. The number of surveys edited is derived from the number of times an existing survey has been replaced by an edited version. The numbers for buildings and places record the number of times the appropriate record was changed.
Number of surveys, photographs and audio files added
This graph gives additional information about maintenance activity and shows the number of new surveys, pictures and audio files added each month. These figures are approximate.
