27976 - Land Survey and Representation

Learning outcomes

After completing this course the student has the knowledge of
1) fundamental principals of remote sensing, with special regard to the applications in the field of thegeological sciences.
2) managment of geological data sets, with special concerns on digital geological mapping and the use of a geographic information system (GIS).

Course contents

Remote sensing (Prof. Jo Hilaire Agnes De Waele)
Principals of remote sensing,History of remote sensing,Physical laws (electromagnetic waves,radiation laws), interaction between energy andmatter(emission, reflection, transmission, spectral signature of natural surfaces), observation systems (concept of resolution, colorimetry), instruments (sensors, passive and active systems), Methodologies for the elaboration and for the analysis of images e, Remote sensing and Geology, Remote sensing and Geomorphology, Remote sensing and Vegetation, Remote sensing and hazards,other applications.

Teaching methods

Remote sensing.
The problems related to satellite remote sensing, photo interpretation and Photogeology will be discussed and illustrated during the lectures.
A consisten laboratory activity will be held, in order to provide each student with the knowledge, techniques and practices for the interpretation and processing of remotely sensed images aimed at the geological survey.

Digital mapping and GIS
The lectures on theoretical arguments will alternate with lab exercises on GIS freware software, in order to familiarize the students with the common procedures of basic digital cartography and management and query of GIS.

Assessment methods

Written exam with practical part on an image, written test of managment, query and report creation from a data set in a GIS environment, followed by oral examination.

Teaching tools

Dedicated software programs will be used for lectures and laboraty practice
