There has been increased interest in the use of sensing devices in the detection and classification of subsurface objects, particularly for the purpose of eradicating Unexploded Ordnance (UXO) from military sites .The Geophysical Template Matching System (GTMS) is a cluster-based framework for the storage and analysis of spatial data sets derived from scanning subsurface objects using geophysical sensing devices. Current approaches to the UXO detection and classification problem have met with limited success. The template matching approach employs libraries of templates extracted from known objects. Coarse grain parallel processing techniques are used to speed up the matching algorithms with one grain parallelism also planned. The user interface is via the World Wide Web providing interaction, a graphical user interface and convenient access from remote locations.
