The Joint Agency Commercial Imagery Evaluation (JACIE) team was formed in 2001 to pool federal agencies' resources in characterizing commercial remote sensing data — and to share the results across the remote sensing community.

The partners work together regularly on technical questions and plan an annual workshop.
What it checks
Data-quality experts make independent assessments of images and of products made from them, each partner agency bringing its own resources and strengths. They look at three main kinds of quality, following a common set of JACIE Best Practices:
- geo-positional
- spatial
- radiometric
Together these results describe how good the imagery is, which strongly affects how usable it is for a wide range of Earth science work. JACIE shares what it learns about the quality and usefulness of remote sensing data available to government and private users.

The quality work matters, but the most important part of JACIE is the close collaboration it builds between government and non-governmental organizations, to understand remote sensing information and make it more useful to the people who rely on it.
The workshop and the tech team
Each year the assessments are presented at the JACIE Workshop, a week-long event for several hundred people from government, industry and universities — a well-regarded, independent forum on the characterization and use of commercial imagery by the public sector. Presenters also share updates on current and future sensor improvements and promote new uses and data products. The program includes talks on new systems, new ways to analyse and improve data, and how data quality affects applications, along with poster sessions, exhibits, side meetings and networking.

As of 2024, the team also holds monthly tech team meetings for partner agency and contractor staff, usually with a guest speaker from an agency or an outside group.
