terms of triangulation, DTMs, orthophotos, mosaics and 
perspective scenes, digital photogrammetry is revolutionary; 
with respect to the all important task of feature extraction, 
however, it will be but evolutionary until usable automation is 
included in most systems. Wong's phrase “continued 
evolution in automation" (ibid., p. 54) juggled the words again, 
but is very pertinent; Dowman (1996) noted, too, that 
automation is partly successful and is spreading inexorably. 
4.2 Future directions 
It is absolutely certain that the DPW will supersede the 
analytical plotter very soon, though the potential of the latter 
for cost effective map compilation will ensure a continuing 
trade in used equipment. We see fluent, optimised flowlines 
emerging to give photogrammetry massive increases in 
productivity. Project management software, grown from 
intelligent photogrammetric applications of software tools 
designed for manufacturing industry, combined with 
sophisticated image databases and universal use of the 
Internet, will control and monitor the flow of processing, 
which commences with digital cameras and roll film scanners. 
GPS triangulation, DTM generation, mosaicking and feature 
extraction will be the mainstays, all benefitting from 
successful automation. Advances in map finishing will be 
welcome too. Windows NT solutions will appear. DPW 
software will become sufficiently refined and robust to equal 
that of analytical plotters in maturity and productivity. Remote 
sensing, GIS and photogrammetry may well converge, with all 
functionalities combined in every workstation. There will be 
greater use of client server approaches. A moving matrix of 
research organisations, vendors and their people will jostle to 
offer these exciting solutions. Continuing cut throat 
competition between vendors will keep prices and margins at 
their lowest ever, which may inhibit product development or 
even cause the demise of some weaker runners, though there 
will be no shortage of enthusiasts keen to join the race. All 
these directions are logical continuations of trends begun 
during the period 1992-96, when competition and technology 
interacted to offer users DPWs with attractive variety, 
capability, power, maturity and economy. When our 
successors make their report in the 2000 Congress, it will be a 
success story centred on reductions in the cost of mapping.
