| 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 formation 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: Squelettisation and vectorization (~2 h.)
- Topic 3: Extraction of the characteristics of the hydrographic network from a DTM (~6 h)
- Topic 4: Computation of a watersheds asymmetry index using a DTM (~3 h.)
- Topic 5: Computation of the linear density of a drainage network (~2 h.)
- Topic 6: Envelope surfaces - map of summits - from a DTM (~2 h.)
- Topic 7: Image fusion by a local statistics matching method (~4 h.)
- Topic 8: Computation of morphometric indices from a DTM and morphological classification (~2 h.)
- Topic 9: Radar imaging: Calibration of ERS SAR PRI images (~2 h.)
- Topic 10: Radar imaging: SAR signal: phase and intensity computation (~1 h.)
N.B.: The duration of each topic are minimal estimatimations. 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, ArcGIS & ArcView, Statistica and programming in Matlab ...). 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 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 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 numeric 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. Information for the connection to this server will be provided to the students at the appropriate time. |
|
| Assessment : | The evaluation is based on the analysis of a series of particular functionalities and tests appealing these functionalities. Thiese analysis and tests will be reported in a written way by the students and possibly discussed with the teacher.
We reserve ourselves nevertheless the possibility of changing the course of the evaluation and the weight of each part during the year. Of course these changes will be carried out in agreement with the students who will be kept by these. |
