Abstract :
Criterra is a software suite that automatically determines optimum locations and heights in seconds/minutes for security system sensors, and locations for infrastructure and response forces based on dominant mosaic, line-of-sight, time-and-space, Doppler, propagation and other algorithms, executed on a terabyte size 3D geospatial and object database. Inputs include specifications of sensor systems, barriers, and response forces. Criterra is based on a methodology that integrates intelligence and scientific processes to quickly and automatically determine optimum locations that are NOT trial-and error. Criterra Automatically calculates: 1) threat paths and predicted locations, 2) the optimal locations for the minimum number of minimum height sensor towers, mobile sensors, and/or unattended ground sensors, and communication repeater towers to meet detection, surveillance and reconnaissance requirements considering predicted threat locations/levels within area use constraints, and 3) placements for fences, infrastructure and response forces within constraints to accomplish protection and interception with high degrees of confidence. The results are displayed on a visually rich and geospatially accurate 3D map which the user can navigate or use for computational model modifications, redefinition of constraints, and further analysis and planning. Criterra can be used now to support land and maritime border security threat, sensor, infrastructure, and response analysis and geospatial planning; physical security analysis and geospatial planning for protection of airports, seaports, military bases and other critical infrastructure; attack and disaster preparation, recovery, and response planning; and force management and collaboration using 3D maps with results of Criterra analyses as embedded mission data. Criterra performs geospatial analysis to predict threat location at specific times, and provides area use data for CONOPs and risk analysis. Criterra is used in require- ents definitions, installations, training, operations, experimentation, and test and evaluation. Criterra can support analysis of small and extremely large areas and catastrophic events. Criterra is a predictive technique for pre-placing mobile or fixed resources; and locating and tasking first responders. It supports situational understanding, information management and data visualization on a 3D geospatially accurate laptop display. Users can use Criterra for information sharing, collaborative decision making and integrated/interoperable decision support where all users are referencing and plotting data on a shared 3D geospatial map. It can support decontamination and restoration strategies, approaches, and sensor placements following WMD events. Facilities, monuments, airports, seaports, transportation infrastructure, land and coastal borders, and ports of entry are all areas where Criterra computational models and Criterra analysis algorithms can be used to determine optimum locations. Criterra computational models and analysis algorithms are used today to plan the optimum locations for ground surveillance and communications repeaters for protection of critical infrastructure, borders and for ports. Criterra is used for planning security for people and facility assets. A Criterra database consists of two types of data: 1) 1 meter square slices of an area, (size limited only by the storage media), containing for each slice: latitude, longitude, height/altitude, terrain composition, slope, use (such as threat, allowed for sensor installation, road, asset ...), derived from GIS data (such as DEM and DTM), and object data (such as buildings, infrastructure, vehicles ...); and 2) radar, camera, UGS, radio, response force and barrier specifications. Criterra algorithms analyze the slices and add to the database for each slice, a) line-of-sight connectivity factors to all other slices, and b) traverse-ability factors to all other slices.
