Instrumentation - Added value

In the earth sciences, observation are essential. Because of our need to optimize acquisition, innovative instrumental devices are necessary and accompany scientific advances : (1) a laser vibrometer to remotely measure the ambient vibrations of a structure, (2) analysis of 20 years of instrumentation at Grenoble City Hall (part of the RAP-RESIF network) to define reference vibration models in buildings, (3) the CityShark II user-friendly station for ambient vibrations recording, (4) the experimental evaluation of rotation sensors in structures, (5) the use of optical fibers in cities (Distributed Acoustic System DAS) to image and monitor the evolution of assets on different time scales, etc...

How can we transform data into knowledge and value ? A FAIR (findable, accessible, interoperable and reusable) data infrastructure is essential. Only then can data be easily shared and explored using advanced analysis methods (such as artificial intelligence). Making data "findable and ready" will change the way science is conducted today, thanks in particular to databases associated with national infrastructures for distributing either data from national instruments, or product databases derived from such data.
