1. Introduction The Problem...

“Accumulation of data is meaningless unless it is underlain by a clear definition of our goals and our definitions about how we shall use and structure that science towards an informed, decision-making process.”

(Bruce Babbit, Chairman of the federal Data Committee, 21 May 1996)

7

1. Introduction The goals and the problematic

1. Scientific informations are often dispersed and are generally not

easy to obtain

2. A Data Base gathers all useful information in only one place,

easily accessible to work and to analyse

3. Spatial, qualitative and quantitative management of the

application of groundwater exploration techniques

4. Finally to have a platform for retrieving questioning manipulating

and formatting data to be used in order to manage water system

8

1. Introduction Spatial Modelling of information in 3 D

GIS, method to :

• view, and represent spatial data

• connect a map with his data base

• manage, analyse spatial data

Coupling of GIS and dynamic models in

environmental sciences

2. GIS : Geospatial Information System 2 approaches

• 1° Inventory and data management (for single view)– Inventory

– Data Compilation

– Data Management

– Database design

– Mapping

• 2° Advanced Spatial Data Models Analysis– Analysis and Geoprocessing

– Spatial modelling

– Link with geodynamic models

Conclusion and work in future

• These projects allow to develop a rigorous methodology in elaborating powerful tools for the management and the protection of groundwater. These tools give the possibilities and limits in integrating and interfacing the hydrogeological models and the GIS. In this way, the integration of new data in the GIS will ensure a control of the coherence of the groundwater flow system representation. All these informations can help in studying the natural evolution of the water system and the impact of the human activities through a really integrated approach.

• My objective is to integrate all data of Ajoie hydrogeological cartography in a geodatabase and submit this project to Office of Environment of Jura (combination between approach 1 and 2)
