Modular distortion correcting real time SSM/I imagery decommutator and process for producing special sensor applied meteorological images
First Claim
1. A method for applying earth curvature corrections to operational line scan image (OLS) data and special sensor meteorological image (SSM/I) data in a data decommutator, generated by OLS and SSM/I sensors scanning the earth'"'"'s surface, the method comprising the steps of:
- resampling the OLS image data to remove a plurality of image pixels near a center of a scan line and to interpolate an additional plurality of pixels toward an edge of the scan line;
resampling the SSM/I data to remove long track and cross track distortions caused by the SSM/I sensor scan angle; and
adjusting the resampled SSM/I data to compensate for a scan position of the SSM/I sensor.

Abstract
A modular distortion correcting real-time SSM/I imagery decommutator applies earth curvature corrections to operational line scan (OLS) and special sensor meteorological image (SSM/I) data which is generated by OLS and SSM/I sensors on board a Defense Meteorological Satellite Program (DMSP) satellite scanning the earth'"'"'s surface. The OLS image data is resampled to remove a number of image pixels near the center of a scan line and to interpolate additional pixels toward the edge of the scan line. The SSM/I data is resampled to remove long track and cross track distortions caused by the SSM/I sensor scan angle. The resampled SSM/I data is then adjusted to compensate for the scan position of the SSM/I sensor. The OLS data image from the OLS sensor and at least one environmental data record (EDR) image obtained from the SSM/I sensor, for a particular geolocation, are displayed by embedding at least one EDR image into the OLS data image to produce a single combined image which can then be displayed.
