GaugeCam blog – a revival

Posted on December 31, 2021 by Troy

When the GaugeCam project started back in 2009, we documented much of the work through blog posts.

We’re excited to start blogging again in 2022, as we take GaugeCam in new directions. The photoshopped image below shows a site we’re planning on instrumenting in 2022.

Our MESH Software Development Philosophy

Apply Findable, Accessible, Interoperable, and Repeatable (FAIR) principles, to:

  • Maximize use and value of image archives
  • Expedite data triage and generation of hypotheses
  • Shift the time investment to the scientific questions
  • High usability and modular design to include non-(expert) programmers in science and education

GRIME2 and GRIME AI are both released using the Apache 2.0 license
