Abstract: This paper analyzes the present situation of earthquake emergency field survey and its problems, proposes a collaborative framework of earthquake emergency field survey based on WebGIS, JavaScript components, OGC standard and XMPP protocol. The framework is based on the B/S architecture and is designed to use existing Android or PC terminal to communicate with the back-end server. It implements functions of reference map obtaining, disaster point marking and interoperation among surveyors via earthquake emergency field investigation information and multimedia disaster data. The framework is implemented by conducting the experimental system. By primary application, it provides a new method which helps to obtain rapidly the reference map related to earthquake and effective cooperative interaction with survey information for surveyors.

Key words: Earthquake emergency survey, WebGIS, Instant messaging, Collaborative interaction framework
