A Spatial Technology Approach to Campus Security

At present, a number of techniques have been applied to improve campus security, but their efficiency is limited due to the lack of accurate geographic information. This article proposes a Geographic Information System (GIS) based framework for campus security, which organizes all existing security facilities and human factors in a geographic model. To spatialize the campus, Mobile Mapping System (MMS) is recommended as the surveying tool to obtain the 3D database of campus. And the software of ArcGIS, as the second development platform, is employed to build the modules referring to spatial analysis. The new system is evaluated by a simulated evacuation experiment and the results show its efficiency is satisfactory.
