[3] In 1991, following completion of the last significant aid-funded mapping projects, its name was changed one final time to Ordnance Survey International and its main activity became consultancy, primarily in Eastern Europe.
[3] The aerial photographs, maps and survey data were originally kept in separate libraries but were amalgamated in 1984 into a single collection called Technical Information and Support Services.
[3] During 2003 and 2004 The National Archives, the Ordnance Survey and advisers from specialist bodies jointly appraised the collection to determine which records should be kept and by which custodians.
[6] In 2014, a 16 minute Scottish Documentary Institute film entitled 'Sightlines' used photography from the collection to explore the legacy of 20th century aerial survey in Mwatate, Kenya.
[10] Agency surveyors were sent abroad to establish horizontal and vertical ground control for the photography; this was permanently marked and co-ordinated so that the surveys could be the basis for future work.
