The Community Sensor Model (CSM) Application Programming Interface (API) has improved the efficiency of software development for geospatial data exploitation since Sensor Exploitation Tools (SETs) can implement their algorithms using sensor-agnostic approaches that allow the user to plug in the particular sensor model, available from a repository of models, associated with the data being exploited.
Verification Test System (VTS) and Generic Sensor Exploitation Tool (GSET) are GOTS software packages that verify conformance and performance, respectively, of a sensor model that has been built to the CSM API. VTS verifies that the model supports all methods defined in the API with the proper syntax for all inputs and outputs.
GSET performs three main functions: Internal Consistency Testing (ICT), Direct Geopositioning Analysis (DGA), and Precision Modeling Analysis (PMA). ICT verifies that various combinations of methods are consistent with one another. DGA and PMA test the external consistency of the model, i.e., compared to ground truth. DGA verifies reliability and consistency of coordinate generation and error prediction. PMA demonstrates adjustable parameter effectiveness and minimization of systematic errors. Over the past few years, the CSM API has been enhanced from supporting only raster images to supporting an extensible set of families including 3D point clouds and motion imagery as well as supporting geopositioning on other planets.
This briefing summarizes VTS and GSET as it has recently been updated to align with the latest version of the CSM API.
