| Abstract: | Since 1960, photogrammetry has played a leading role in the acquisition of survey data within the Ordnance Survey of Northern Ireland. The decision to create a digital topographic database for Northern Ireland has changed the philosophy and practice of photogrammetry within the organisation and these changes are discussed in this paper. |
