Topography and Field Geology
The main objectis of this course is to allow the student to become familiar with:
- the different basic terminology associated with surveying and geomatics,
- read and interpret topographic maps and perform mapping operations, in particular, coordinate systems transfornation,
- perform simple geological field surveys, introductory to geological mapping,
- useful concepts for subsequent courses wether in the Earth Sciences domain (Geology Portugal, Structural Geology, Geological Cartography and Remote Sensing) or in the Geological Engineering (project or monitoring of various civil or mining engineering interventions).
