| Course contents : | The course covers a series of topics. Some of these topics must be chosen by the students according to their field of research within the framework of their thesis. A certain number of hours corresponds to each topic. The total number of hours corresponding to the chosen topics should not exceed 15h, the official duration of this course. The list of the topics is as follows: - Topic 1: Image segmentation(~4 H.) - Topic 2: Image squelettisation and vectorization (~2 H.) - Topic 3: Extraction of the characteristics of the hydrographic network starting from DTM (~6 H) - Topic 4: Computation of an asymmetry index of watersheds (~3 H.) - Topic 5: Computation of the linear density of drainage network (~2 H.) - Topic 6: Envelope surfaces (map of topographic tops)(~2 H.) - Topic 7: LSM Image fusion (~4 H.) - Topic 8: Computation of morphometric indices from DTM and morphological classification (~2 H.) - Topic 9: Calibration of ERS SAR PRI images (~2 H.) - Topic 10: SAR signal: phase and intensity computation (~1 H.) N.B.: the estimates of duration for each topic are minimal estimates. At the beginning of the formation, the durations can be about 2 times longer than those announced for some topics. | |||||

| Course objective : | The principal objective of this course is to allow, mainly within the framework of the thesis of physical geography, the exploitation of several professional software in Windows environment (Erdas Imagine and ArcInfo + ArcView, programming under Statistica BASIC ...). This course must promote the practical application the theoretical knowledge acquired during various courses of the preceding years of study (remote sensing, spatial analysis, numeric analysis, statistics, mathematics, numeric cartography). At the end of the course, the student will be able to reach a sufficient level of autonomy in the exploitation of these tools to develop his own methods of research and experimentation by discovering by itself the new potentialities offered by these professional tools. During the lectures, those methods are illustrated by a series of applications concerned with space modeling in various fields of the physical geography. A close attention will be paid to the complementarity of these tools: which tool to choose to solve a specific problem? How to ensure, between these various tools, the flow of data and treatments results by using them in alternation. | |||||

| Prerequisites : | The course exploits various statistical treatments studied within the framework of the courses of statistics in 2nd candidature and spatial analysis in 3d licence. Moreover, it frequently refers to the concepts of numeric analysis, matrix algebra and analytical geometry studied during the course of mathematics in 1st candidature. A certain number of concepts of numeric cartography and tools of softwares (Idrisi) learned and handled in 2de candidature are exploited. Some specific concepts are recalled during the course sessions. | |||||
| ||||||
| Organization : | The sessions are generally given at the Institute of Physics (B5, 2d floor, laboratory of image processing and GIS). The schedule is fixed by mutual agreement between students and teacher. Being given the limited number of licences of use of the exploited software, the maximum number of students per meeting is fixed at 4. | |||||
| ||||||
| Written notes : | The course and directed works support consists in a collection of PowerPoint slides, Word documents and extracts of publications and books. The numeric slides are available in pdf file-format, downloadable from the FTP server of the Geomatics Unit ftp://ftp.geo.ulg.ac.be using the student user-id and password. | |||||
| ||||||
| Assessment : | The evaluation is based on the analysis of a series of particular functionalities and tests with regard to the tools used. This evaluation and these tests will be the reported in a written way by the students and possibly discussed with the teacher. | |||||
