8.0 SUMMARY 
It can be seen that the MPS using reduced aerial photography can produce 
results similar to that of a production mapping analogue instrument using 
large format photography. However the MPS can be operated by people with 
little photogrammetric training, is a relatively low cost photogrammetric 
instrument, and it is very portable. The possibility now exists for up to 
date photogrammetric data in "Microfilm" form to become generally 
available to a large body of users. 
Some work needs to be carried out to refine the photo-reduction process to 
maintain high quality reduced diapositives and the MPS should be fitted 
with a 10 micron floating mark for this type of work. If this work is 
carried out and the combined lens distortion of the final diapositive 
carefully determined, the results can be significantly improved.
