This data set is an inventory of aerial photographs held at BGS, Murchison House office and consists of a MS Excel spreadsheet containing 11 worksheets. Each worksheet contains information pertaining to the different sub-collections within the collection (9 worksheets of aerial photographs, one for aerial photograph scans, one for satellite imagery). Quality and coverage of metadata varies from worksheet to worksheet, depending on the size of the sub-collection, its pre-existing organisation, and the way in which the sub-collection was brought together (if it was not a complete entity when the inventory was started). Areal extent ranges from Shetland in the N (1200000) to the southern Lake District in the S (480000) and from Barra in the W (65000) to Stockton-on-Tees in the E (450000). By late 2001 all photos (except those being worked on by cuurently by staff) were catalogued in the inventory spreadsheet. By late 2003, the inventory spreadsheet had been updated with newly purchased and newly discovered photos as well as modified to include details of digital holdings and satellite imagery.
