photography normal to the dome at a range of approximately 2 m. The camera 
was mounted in a specially constructed cradle so that there were no obstructions 
such as tripod legs between the lenses and the dome surface. Restitution of the 
photography was carried out in a Zeiss (Jena) Stereometrograph. Photogram- 
metric plotting from stereograms of children's faces, as reported at both 
the 1968 and 1972 congresses, has continued on a regular basis during the 
period currently under review. 
UNIVERSITY OF GLASGOW, Department of Geography 
Detailed elevations have been plotted for two buildings in the locality. 
HATFIELD POLYTECHNIC, School of Natural Sciences 
The stability of chalk slopes is being investigated using terrestrial photo- 
grammetric methods. 
H M DOCKYARD PORTSMOUTH, Ministry of Defence (Navy) 
Evaluation of photogrammetry applied to interior and exterior warship work 
has recently been completed (45). Various projects including hull form and 
installation layouts were investigated using stereopairs produced from Zeiss 
(Oberkochen) SMK 40 and SMK 120 photography and plotted on the Zeiss (Jena) 
Technocart stereoplotter. Photogrammetry shows potential in this field and 
work is continuing. 
HIGHLANDS FABRICATORS LIMITED, Brown and Root - Wimpey 
Terrestrial photogrammetry is being used at the Nigg fabrication yard to aid 
the dimensional checks required in the fabrication and erection of North Sea 
oil rigs (111, 112). The system used includes a Zeiss (Jena) UMK 10/1318 
camera and 1818 stereocomparator with digitiser and on-line connection to a 
Wang 600 desk top computer. 
HUNTING SURVEYS LIMITED 
Volumetric surveys in the UK using both vertical and terrestrial photography 
have been related to reservoir sites, coal stocks at power stations and the 
stabilisation of potentially dangerous cliff faces. 
Extensive use has been made of terrestrial photogrammetry for the plotting 
of historic buildings, including Camber Castle, Maxstoke Priory, Howden 
Minster and Castle Rising, for restoration and archival purposes. Equipment 
used included the Wild P31 and Zeiss (Jena) UMK 10/1318 cameras and, for 
plotting, the Wild A5.
