| Abstract: | Orthophotomaps at 1 : 2500 scale, contoured at 1 m vertical intervals, have been produced for an area of 52 km2 from 1 : 10 000 scale photography especially flown for the project. Planimetric and height information on published Ordnance Survey 1 : 2500 scale maps was used as control for the aerial triangulation on which the orthophotomapping was based. |
