NGA has been involved with the Community Sensor Model (CSM) Application Programming Interface (API) and in providing guidance for its future; and now its paradigm is shifting from the concept of many specific sensor models to a few generic sensor models by family. The generic model concept is enabled by establishing standards for upstream data providers to supply metadata with their image products. NGA has designed a set of six "Common Sensor" (CS) metadata components that will soon become part of the NITF standard and facilitate generalization of all EO/IR sensor models whether they are line scanners or framers, and whether they are panchromatic, MSI, or HSI. Framers can collect a still frame, or a sequence of frames captured in either a step-stare or spotlight mode to support wide area collection or motion imagery collection, respectively. An "A" version of the CS TREs had been designed several years ago, but is inadequate in several areas that will be accommodated by the "B" version; e.g. the "A" version only applies to line scanners and does not contain any mechanism to store error covariance (uncertainty) information. So, the "B" version will support exploitation of emerging commercial imaging systems like Skybox which can collect motion imagery. The photogrammetry and error modeling aspects of this new generic sensor model and metadata structure will be presented in a 50 minute briefing followed by 10 minutes for questions.
