Objectives

The module treats of the main technical production methods of a digital mapping and introduces the characteristics of the Geographical Information Systems, applied for the activities of planning, management and design of civil and environmental engineering.

Acquired skills

- To know the map projection theory of the italian Local Administration cartography
- To design, to lead and to verify the digital mapping production phases by photogrammetric survey
- Aerial and terrestrial Laser scanning survey and data management
- To create and up-to-date territorial data bases by scanning and georeferencing an existing map
- To know the technical specifications of the digital regional technical mapping and the characteristics of the Italian Cadastre
- To know and to apply Geographic Information Systems for planning and management of the territory and for the civil design
