Résumé : This paper proposes a reflection on the relations between the observatories, the Spatial Data Infrastructures (SDI) and the user needs for the spatiotemporal and the environmental monitoring. After a reminder of the nature and objectives of the observatories and the SDIs, we analyze from case studies different observation systems, the availability of collected geographical data using various SDI and the adequacy of these infrastructures with the needs and means of the users. We will rely on multispectral (satellite and aerial) imagery collection and hydrometric data collection (streamflow measurements) to illustrate some of the numerical challenges observatories face in achieving their goals.
