Exploration and assessments of the application of innovative fusion methods to a suite of ground, aerial and space-based sensor data for the
• detection and identification of surface and subsurface archeological features
• identification of best modality and modality mixes
• development of COTS based multi-instrument fusion software capabilities

AccomplishmentsFrom our QPR…• T1. Installation Coordination
• T2. Acquire aerial, thermal and satellite data– Acquire thermal data at Ft
Benning – Acquire thermal data at
Savannah River • T3. Geophysical fieldwork
– Ft. Bliss completed• T4. Preprocess data sets
– Satellite imagery– Ft. Bliss geophysical data– Ft. Bliss ATLAS– Ft. Benning geophysical– Savannah River
geophysical– Ft. Riley thermal
Processing of initial thermal data has yielded substantial problems with data quality including low dynamic range and jitter in frame grabber. Development of new processing approaches and acquisition of new recording device are anticipated to correct problems and acquisition is to be repeated (at no cost to project). A second attempt to acquire imagery on 3/27/2004 was unsuccessful due to aircraft platform instability from high winds. The sensor properties require a very slow flight speed. A third no-cost re-flight is planned.
