ABSTRACT 
Technological development and new fields of applications lead to a continuing expansion of 
the scope of photogrammetry. Non-topographic applications of photogrammetry and remote sen- 
sing are just two of the areas where rapid developments are taking place. Educators must respond 
to these changes. A rigorous course on the concepts is required as the foundation followed by a 
series of application courses. The mathematical and physical bases and the methodology require 
expansion beyond those applied in the main stream of photogrammetric operations. The authors 
examine the special conditions and needs associated with these growing’ fields of activity and 
suggest means for preparing students to handle these tasks at a professional level. 
INTRODUCTION 
At most educational institutions, the teaching of photogrammetry is focussed on its main 
application which is mapping. It is based on standard photogrammetric equipment, i.e., metric 
cameras, analogue stereoplotters, comparators, rectifiers, orthoprojectors, and perhaps an analy- 
tical plotter, as well as on standard evaluation procedures, i.e., parallax equations, similarity 
transformations, and strip and block adjustments, 
The subject is presented in two distinct packages: analogue photograpmmetry, ‘the science 
without mathematics’ utilizing optical-mechanical means to obtain graphical results; and analyti- 
cal photogrammetry, where the physical relationships are modelled mathematically to obtain 
numerical values, e.g., a list of coordinates. The treatment of aerotriangulation is a prime exam- 
ple of this approach, It is primarily regarded as a support activity for mapping and is categorized 
as analogue, semi-analytical and analytical. 
In addition to the quantitative, geometric aspect of photogrammetry, the qualitative aspect 
is covered in photointerpretation, where the pictorial information is being analysed primarily by 
visual means, mostly again in support of (thematic) mapping. 
Technological advances in recent decades have left their mark on photogrammetry as well. 
While mapping remains a central issue, many other applications are appearing. Updating curricula 
by merely inserting the discussion of new technologies, quickly leads to obsolescence. Educational 
institutions must strive to impart knowledge in a manner that remains relevant throughout the 
professional career of their graduates. 
RECENT EVOLUTION OF PHOTOGRAMMETRY 
Technological developments affect ail aspects of photogrammetry, from the input phase to 
the output phase, and can only be highlighted in a presentation like this. While the input, or data 
collection, phase will continue to utilize metric photography, there are now many other data ac- 
quisition devices available. Not only are there non-metric and semi-metric cameras, but also many. 
non-photographie sensors, such as video cameras, digital cameras, line scanners, microwave sen- 
sors, etc. In fact, photogrammetry could be regarded as a branch of remote sensing which deais 
with quantitative analysis of image data.
