Applications in engineering, architecture and industry have been based on the 
use of a Wild C120 camera and A40 stereoplotter. Several tunnel surveys have 
been carried out in the UK to determine alignments with plotting at scales of 
1:50 and 1:100. The problems resulting from earth slips have been investigated 
both at home and abroad. Actual slips in Nepal and Colombia have been photo- 
graphed and plotted in conjunction with the Transport and Road Research 
Laboratory, whilst at home the settlement and final collapse of earth banks 
has been monitored. At Edinburgh a survey of part of the Castle Rock was 
made; the contoured plans then assisted engineers in their task of stabilising 
the rock mass to prevent subsidence and damage to the Castle. Several 
historical buildings and bridges have been plotted at scales of 1:25 and 1:50 
to provide base documents for maintenance and restoration. The increasing 
emphasis on attempting to preserve the environment has led to a variety 
of tasks involving restoration. Organ cases from several churches in 
The Netherlands, notably in Utrecht and Amsterdam, have been photographed 
and plotted at scales ranging from 1:10 to 1:50. External restoration at 
Exeter Cathedral and Wells Cathedral (in conjunction with University College 
London) has required the production of photogrammetric plans. Property 
development in the Bow Lane area of London necessitated the taking of over 
500 stereopairs and the production of plans and elevations at scales of 1:100 
and 1:200. These drawings have been used to help to preserve the character 
and appearance of the site. 
Perhaps the most unusual application has been in the field of paper technology. 
Paper manufacturers have had problems in defining the surface of their 
various papers in a satisfactory quantitative manner. Photography was obtained 
in conjunction with a manufacturer and the resulting plots at a scale of 20:1 
allowed contours at a 10pm interval to be plotted, relative accuracy being 
the paramount objective.

A major research project has been concerned with the general application of 
photogrammetric measurement in dentistry and medicine. To date the studies 
have involved the measurement of changes in facial shape following treatment 
by orthodontic and surgical means, and the measurement of palatal surface areas 
as part of a study to compare the palatal development of normal and cleft 
palate children (51, 52). These studies have been undertaken in conjunction 
with clinicians working in the Newcastle University Hospital Group and the West 
Midland Regional Plastic Unit. Work has been carried out to assess the value 
of photogrammetry in checking the components and assembly of two types of 
marine structure, fixed base offshore platforms and ships (111, 112). This work 
has been carried out in collaboration with the British Ship Research Association 
and with Longdin and Browning. The facades of a derelict 17th century farm- 
house in County Durham have been surveyed at 1:24 scale to assist in 
restoration and rebuilding work. For photography both Galileo-Santoni A Special 
and Zeiss (Jena) UMK 10/1318 cameras have been used. A Wild A7 with EK5a 
as well as Zeiss (Jena) 1818 and Hilger and Watts stereocomparators have been 
used for measurement.
