The Research On Earthquake Rescue Operations Symbol

The earthquake features are significantly marked by suddenness and devastation. It never failed to be one of the main nature hazards that cause economical loss and casualties in human history. The effective earthquake rescue is still an international priority to narrow economical loss and casualties after the destructive earthquake’s occurrence since the earthquake prediction is still a world-class problem. The key to get victory in the rescue work is the rational and effective rescue. Making symbol is the most important tool for transmitting correct and real-time rescue information to victims and greatly regulate the scene of action.As a kind of symbol, the earthquake rescue-operations symbol should have the basic elements of symbols that is Peirce’s trichotomy of sign, which include earthquake rescue operations symbol, earthquake rescue operations information and interpretation of the earthquake rescue operations symbol. The earthquake rescue operations symbol can be classified of image symbol, making symbol and symbolic symbol in accordance with the basic symbol classification.The use of earthquake rescue operations symbol is also a communication process. According to the study of four dissemination elements which are icon, index and symbol, we define the user of earthquake rescue operations symbol, including the commanding officers, rescuers and victims. Those three kinds of people’s need are different, and the different of the spread of vectors, thus they provide the basis for the generalization of rescue information and the design symbols.The study contents of the earthquake rescue operations symbol is the earthquake rescue operations information, so we must fully grasp the earthquake rescue process, summed up the characteristics of the rescue, and summarizes the earthquake rescue of operations information. Then according to the principles of information classification and some classification methods, the earthquake rescue operations symbol system are obtained by classification of the earthquake operations information.As a profession symbol, the earthquake rescue operations symbol possess both commonality and particularity. The most important method is referencing and modifying the existing symbols, designing new symbols. When creating a full completed symbols system, it must follow specific principles must be followed when designing a new symbol. Different design principles are applied for signal symbol and electronic symbols since they have different media and characteristics. Then a symbol system for China earthquake rescue is available which is compatible with the given design principles.It is necessary to establish the corresponding electronic symbol library that make the designed symbols work live in the thematic map. according to the style of ArcMap, the thesis has completed the implementation of a electronic symbol library which can be used in the software developed by ArcEngine. The symbol library contains three kinds of styles, point, line and planar. To display the symbols on the map, the achievement of the symbolic process is high lightly researched. Finally, some relevant thematic maps are given.The designed symbol presented in this graduate thesis could serve as a highly productive reference for the establishment of Chinese earthquake rescue operations symbol standard, which can also speed up the perfection of China’s earthquake rescue system.
