Basics of surveying. Cartography. Data acquisition for Geographic Information Systems. Digital Terrain Models. Orthophotomaps. Conceptual foundations and basic operational skills with GIS software; acquisition, maintainance and interchange of data bases; examples of applications; prescriptions and quality control in tenders for map production

Basics of surveying: geodesy, survey instruments (total station, levels, GPS), surveying techniques.
Cartography: conformal and equivalent maps; map contents and map generalization; tolerances; italian state and regional maps.
Digital cartography: Definitions and differences with traditional maps. Contents of digital maps. Information coding. Structures for data archiving: raster and vector. Raster and vector data; topographic data bases. Raster data: Geometric resolution and discretization of information. Digital terrain models. Digital orthophotomaps. Vector data: structuring geometry and topology. Raster data acquisition: Rasterization of maps, satellite images, orthophotos, DTMs; mosaicking; georeferencing raster data.
Vector data acquisition. By photogrammetry, by vectorization of existing maps. Cartographic editing. Numerical cartography for municipalities: contents, technical prescriptions and quality control.
Raster data acquisition. Rasterization of maps, satellite images, orthophoto, DTM; mosaicking; georeferencing raster maps.
Geographic information systems. Basic components. Manipulation of raster and vector data: connection to external databases; queries; processing of raster data; visualization and representation of results. Examples of GIS software. Total 63 hours: 45 lectures, 18 exercices
