THE STEREO PLOTTING SIMULATOR (SPS)
Although normal stereoplotting instruments are usually used for training photogrammetric
operators, it has proved to be both inefficient and ineffective [Jerie, 1968.] The high degree of
accuracy and the numerous application possibilities offered by commercial equipment are not
needed for teaching basic skills Using actual production equipment is also not effective from a
ted, adapted didactic point of view because the degree of complexity of the equipment implies that the trainee
llar mapping has to pay attention to too many different skills simu Itaneously. For in-service training, the use of
production equipment creates conflicts between production and training needs.
duced in the Taking these problems into consideration, ITC-in the late 1960s—produced the ITC Stereo-
the training | trainer, a training simulator. At the ISPRS Congress in Hamburg, an improved version of the
hermore, the | Stereotrainer was presented, the Mark Il — 1980. The fully mechanical simu lation solutions, how-
sed with the ever, limited the use of the simulator to teaching only the pure plotting skills By adding electro-
the standard nic components (encoders, motor-drivers, microprocessors) to the Mark Il version, these limita-

The only visible difference between the Mark 11—1980 Stereotrainer and the SPS is the addi-
tion of a microprocessor, a control panel and a (semi-automatic) drawing table (see Figure 6).
Actually, it is a completely new design in which mechanical movements and transmissions have
been replaced by motor drives, encoders and a microprocessor. The instrument has in fact become
a low accuracy analytical plotter, which has increased its capabilities enormo usly.
