Topography - KAGG6M18

Goal(s)

Acquisition of theoretical knowledge which enables them:

• to be able to establish (or understand) the technical specifications focused towards their own activity
• to acquire the main knowledge that can be useful to them in terms of cartography and geolocation
  Handling of topographic Instruments in the field and realization of post treatments associated with the measures carried out in order to:
• better understand the concept of accuracy related to instruments used and associated operating modes
• concretize the theoretical knowledge relating to the topographic surveys which can be realized within the framework of their activity of geotechnician
