Palette /Sensor Performance Monitoring (SPM)

Bad Pixel Identification and MappingIdentifies bad pixels according to type of defect Saturated Non-Responsive Over-Responsive

Replaces bad pixels according to a user selected algorithm Nearest Neighbor Mean Minimum/Maximum

Palette is an integrated suite of tools for processing & exploiting data from all OPIR sensors. Palette is built on Opticks, an open-source remote sensing analysis tool for GEOINT, and ArcGIS for geospatial analysis. In addition to OPIR, Opticks also supports the processing and exploitation of Imagery, Hyper-Spectral, Multi-Spectral, Thermal Infra-Red (TIR), and Synthetic Aperture Radar (SAR) data. Operates in both connected mode (interfacing with IOTS services) and stand-alone mode

(read/write from file system) Provides event and scene-based processing capabilities DoDIIS Certified – Oct 2011 Deployed at more than 25 organizations world-wide,

including: NGA, NASIC, OPIR ground sites, ARSTRAT, NGIC, other intelligence agencies, multiple partner locations When coupled with ESD, OPIR users can search, download,

and process OPIR data and publish OPIR products Selected by NGA to provide OPIR scene based analysis for

the entire OPIR enterprise comprised of both GEOCOMPASS (GC) and IOTS. Palette will be integrated into GC during GC Increment 6
