1008279 - TELERILEVAMENTO E GIS A - Z

The course provides the basic notions of multispectral and radar remote sensing as tools for territorial monitoring and the construction of thematic cartography. It also provides the knowledge necessary for creating and managing spatial information in a GIS environment.

Teaching is provided through lectures and practical exercises with the use of topographic software and tools. If necessary, teaching could be provided remotely.

Basic knowledge of Topography and Cartography are required.

1. Digital cartography. General characteristics of the digital cartography. Structure of raster data. Georeferencing of raster images, world file. Vector cartography: entities and geometric primitives. Spatial relationships between geographic entities. Structuring topological vector data. The geographic information in GRID format, digital terrain models (DTM-DSM). TIN model for representations and 3D analysis of the territory.

2. Remote sensing. Background. the physical principles of remote sensing. The electromagnetic spectrum; remote sensing in the visible, infrared and microwave. Types and resolution of acquired images. natural radiation issue: laws of Planck, Wien, Stefan-Boltzmann. Outline of absorption and diffusion of radiation. passive and active remote sensing sensors. Main applications of radar sensors and nods to interferometric techniques. satellite orbits. aerospace missions for earth observation. Problems and methods of processing and interpretation of remote sensing data. Techniques for the classification of remote sensing images and production of thematic maps.

3. Geographic Information Systems. Architecture and functionality of a GIS platform. GIS functionality: editing and management of spatial reference data selection, query, overlay, buffering. Advanced spatial analysis. Display and output. Data Base (DB) and Data Base Management System (DBMS); Layout and properties of a relational DB, data models, conceptual , logical and physical data modeling. The Entity-Relationship model: general constructs, restructuring and normalization of the E-R diagram. Features and architecture of a DBMS (external, logical and physical level). Description and employ of  the free and open source software QGIS.

In itinere tests in written form (not compulsory) and with final evaluation, reserved only for students who have attended at least 70% of the lessons.

Oral exam for all ordinary and extraordinary sessions. The exams can also be carried out remotely; in this case only in oral form.

The evaluation of the exam will be based on the following elements: relevance of the answers to the questions asked, quality of the contents, ability to connect with other topics covered by the program, ability to formulate examples, technical language properties and overall expressive ability of the student.

raster and vector primitives - georeferencing of raster images - physical principles of multispectral remote sensing - passive sensors - spectral signature - chorological mapping - classification of multispectral images - GIS architecture and functionality - advanced functionalities of spatial analysis - constructs of E-R diagrams - logical DB modeling
