Introduction to cartography and spatial information systems. The problem of the representation of the earth's surface. Reference surfaces, coordinate systems, reference systems. Transformation of the reference surface - map plane (perspective projections, projections for development). Outlines of some important types of cartographic representations. The official Italian cartography. The cartography of the Istituto Geografico Militare (classification, cartographic system, basic elements, maps available at various scales). Regional technical cartography.
Cartographic data and digital models. Representation models for digital data: raster and vector formats. Secondary data acquisition. Digital terrain models (definition, acquisition, processing and archiving of a DTM). Interpolation methods for lines and surfaces (nearest neighbour, weighted average, polynomials, splines,). Standards for the quality of geodata and evaluation of the quality of geodata.
GIS and Internet. WebGIS, Geoportals and IDTs for spatial information; interoperability of geodata (technological and semantic); standards for geographical information; Internet-supported services for geodata and geographical applications.
