Number of surveys, pictures and soundfiles delivered

This graph shows the total number of organ specifications, pictures and audio files delivered to users during each month in 2013. The NPOR software and database were re-designed and re-written during 2013 and the new version was installed in September. As part of this work the statistics became more accurate which has resulted in the totals being smaller now that probes and search engines are more effectively removed.

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 in 2013. The number of surveys edited is derived from the number of times an existing survey has been replaced by an edited version.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.
