Title: James A. Hammack: Innovator in Geospatial Technology
Introduction
James A. Hammack is a notable inventor based in Long Beach, Mississippi, who has made significant contributions to the field of geospatial technology. With a total of three patents to his name, Hammack has developed innovative solutions that enhance data processing and image analysis.
Latest Patents
One of Hammack's latest patents is the "Geospatial data abstraction library (GDAL) conversion tool for data compression." This invention provides methods and apparatus for creating super-compressed map files. Utilizing free and open-source software (FOSS), the tool generates a super-compressed internally tiled Geo Tag Image File Format (TIFF) in a WGS84 datum. This innovation is similar in size to the original LizardTech's MrSID imagery from the National Geospatial-Intelligence Agency (NGA). By converting NGA data to WGS84, mapping systems like NASA Worldwind can eliminate the need for re-projecting on the fly from non-native projections, thereby reducing processing time. The disclosed method includes removing all pure-black pixels, changing near-black border pixels, setting pure black values to 'no-data,' compressing the image, and translating it to JPEG and a YCbCr color space for greater compression.
Another significant patent is the "Method and system for real-time automated change detection and classification for images." This computer-based system and method determine if a change detection sonar contact in change detection side scan sonar imagery matches a historical contact of the same geospatial location.
Career Highlights
Hammack's career is marked by his work with the United States Navy, where he contributes his expertise in geospatial technology. His role involves developing innovative solutions that support military operations and enhance data analysis capabilities.
