Given to the specificity of positioning in fire ground, inertial navigation positioning technology based on Pedestrian Dead Reckoning (PDR) is most widely used. Stride estimation algorithm is the core of PDR. In order to improve the accuracy of it, in this paper, we selected three factors of stride (acceleration amplitude, step frequency and height) to build an empirical model for stride estimation...
In this paper the construction of Chengdu land resources E-government system is taked as an example. Combine each service of land resources closely, the existing fundamental data and the thematic data are integrated. By using present information technology, the sharing model and the solution of releasing and sharing the massive data based on the OGC service are proposed. The integration and application...
This paper presents a method to integrate computational models in emergency intelligent decision support system (IDSS) for more scientific and effective loss prevention and disaster manipulation. Various computational models that support disaster evolution forecast, impact analysis on infrastructure and human as well as rescue actions are integrated in this IDSS. Moreover, the pertinency between original...
This paper presents a method to integrate GIS and computational models in emergency intelligent decision support system (IDSS) for more scientific and effective loss prevention and disaster manipulation. The value of GIS in emergency management arises directly from the benefits of integrating a technology to support spatial decision making. Now many simulation models requiring spatio-temporal information...
