| Abstract: | The main activities carried out by Ordnance Survey Ireland are focused on the production and maintenance of both small and large scale topographic databases. In 1980, photogrammetric methods were extensively adopted to carry out these tasks, based on analytical procedures. A review of operating practices in 1992 led to the introduction of digital systems. The technical complexities of the installation of digital hardware and software in a production environment are reported in this paper. An expanded role for the photogrammetric department also required the acquisition of new skills by its personnel. Experience has shown that further development, based on co-operation between vendor and user, must continue in the digital field. |
