Re: Provenance and observations and measurements

Dear Carl,

Indeed. It was me who mentioned the measurements. I fully agree. In my follow-up e-mail,
I described it as scientific observation. Geo-applications are indeed a huge area, may be
with the most massive data production currently,

but there is also ecology, biodiversity, clinical studies, astronomy, experimental records in
physics, chemistry, microbiology. Further there is archaeology, ethnology,
experimental neurology, psychology, sociology, forensics...

best,

Martin
