Through Army STTR Phase I and Phase II efforts, a flexible image manipulation architecture has been created and fielded based on the GeoTIFF version 1.0 format. This global commercial standard allows the display of vector, raster and matrix datasets in both 2D moving map systems and 3D real time perspective fly-through displays. The architecture is currently fielded in a JSOC Phase III production contract called "Jagged Shadow Digital Call for Fire System". While any GIS dataset can be manipulated with version 1.0, a separate file is required for each different data type and resolution. The proposed effort will add the important ability to integrate multiple resolution raster images for the same geographic area. The specific scientific advances transferred from JPL include their pioneering work on variable resolution image manipulation. Dubbs & Severino, Inc. has already converted their GeoTIFF v 1.0 architecture into a portable workstation which runs under Windows NT 4.0 on inexpensive Intel Pentium computers and this effort will similarly maximize the use of these proven globally pervasive COTS solutions.
