  • How GlS Supports the Fight Against Terrorism

    Read More

    Every incident of terrorism provides a learning curve for the use of GIS and other geospatial technologies in the fight against terrorism. Little empirical work on the spatial and temporal aspects of terrorism exists. So, theoretical models are applied in combination with historical records of terrorists or terror organizations. There is plenty of potential for research, especially in the mashup of technologies that use Big Data and social media activity like tweets to pinpoint location of terrorists; LiDAR and LADAR for 3D mapping and combat operations, geo statistical software for modeling and predictions.
