| 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 15 h, the official duration of this course. The list of the topics is as follows: - Topic 1: Image segmentation(~4 h.) - Topic 2: Ssquelettisation and vectorization (~2 h.) - Topic 3: Extraction of the characteristics of the hydrographic network starting from DTM (~6 h) - Topic 4: Computation of watersheds asymmetry index (~3 h.) - Topic 5: Computation of the linear density of drainage network (~2 h.) - Topic 6: Envelope surfaces - map of topographic tops - from DTM (~2 h.) - Topic 7: Image fusion by the Local Statistics Matching method (~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 duration can be about 2 times longer than the one 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 softwares in Windows environment (Erdas Imagine and ArcGIS & ArcView + programming). This course must promote the practical application of the theoretical knowledge acquired during various courses of the preceding years of study (remote sensing, spatial analysis, numeric analysis, statistics, mathematics, numeric cartography, programming). 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 spatial modelling in various fields of physical geography. A close attention will be paid to the complementarities 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 and spatial analysis. Moreover, it frequently refers to the concepts of numeric analysis, matrix algebra and analytical geometry studied during the course of mathematics. A certain number of learned concepts of numeric cartography and remote sensing and handled softwares tools (Idrisi) are also exploited. Some specific concepts are recalled during the course sessions. | |||||
| ||||||
| Organization : | The sessions are generally given at the Institute of Physics (B5a, 2d floor). The schedule is fixed by mutual agreement between students and teacher. Being given the limited number of licences of use of the exploited softwares, the maximum number of students per session is fixed at 6. | |||||
| ||||||
| Written notes : | The support of the course and directed works 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. | |||||
| ||||||
| Assessment : | The evaluation is based on the analysis of a series of particular functionalities and tests with regard to the studied tools. These analysis and tests will be reported in a written way by the students and possibly discussed with the teacher. | |||||
