6. ANALYSIS OF GEO-ENVIRONMENTAL DATA
Non-spatial exploratory analysis
Aspect of distributions in geology and the environment.
Theoretical distribution models and their parameters.
Topological analysis
Structural analysis and spatial autocorrelation
7. SPATIAL MODELLING OF GEO-ENVIRONMENTAL DATA
Global inference vs. local inference
Spatial inference through deterministic models |
|
| Course objective : | 1) To make students understand the importance of a quantitative approach to earth and environmental sciences (SIG, Imagery, Geostatistics, etc.).
2) To master the basic graphic visualisation techniques of geo-environmental data.
3) To analyse and interpret the statistical parameters and the laws of distribution generated by the different environmental processes.
4) To understand the deterministic spatial inference models and their limitations.
5) To be familiar with the use of the essential software programs. |
|
| Prerequisites : | None |
|
| Workshops : | Practical work is done using MATLAB.
After an introduction (refresher) to the use of MATLAB and several supervised pieces of work, students will be required to carry out a thematic project using MATLAB, which will be the subject of a written report submitted for assessment.
Students may use a laptop insofar as this is possible. |
|
| Organization : | Second quadrimester - Wednesday PM
The theoretical classes are taught in English in two-hour modules. The transparencies used in class as well as any written notes are in French.
Each theoretical class is followed by two hours of practical work (in French). |

| Assessment : | A written exam is organised at the end of the semester. This exam relates to the theoretical aspects of the subject and contains questions relating to hypothetical situations.
Students have to carry out a personal project within the framework of their practical work, to be handed in at the end of the semester.
The theoretical exam counts for 75 % of the final mark and the practical work for 25 % (both are compulsory). |
