3.2 The TPPO modules: 
4. Cone 
The T?P0 is organized around 12 teaching/learning modules (each including 
theory and practice in an average ratio of 20% to 80% respectively). Those 
modules are arranged in a logical flow of teaching/learning activities for a 
beginner in photogrammetry (see Fig. 2). However, depending on the needs of 
the Mapping Organisation and/or on the background of the trainee, the TPPO 
can be entered at any stage and geared towards particular photogrammetric 
activities. Each module is self-containing, provided the entry requirements 
are fullfilled.
