SUMMARY 
The ever quickening trend towards computer -aided road 
design has directed the attention of highway engineers to the value 
of Photogrammetry in providing terrain information at a speed 
and cost commensurate with the subsequent design process. 
Some degree of mutual understanding by photogrammetrist 
and engineer of each other's problems is essential if their alliance 
is to prosper, since the success or failure of any computer-aided 
project is largely dependent on the user's grasp of the process as 
a whole. 
This paper describes briefly the design process and the 
photogrammetrist's role in that process, warns of some of the 
pitfalls awaiting users of computer - aided systems, and attempts 
to dispel the commoner misconceptions surrounding the technique.
