Design And Implementation Of Field Survey Information System For Geological Disaster Based On Andriod

The field investigation of geological disaster is a prerequisite for geological disaster monitoring, management, is a geological disaster prevention and control planning at all levels to prepare scientific basis, effectively avoiding basic geological disaster work injuries. The rapid development of computer, network, wireless positioning technology and mobile platform development technology for field survey, geological disasters information acquisition in the realization of mobile phone in the mobile terminal has created favorable conditions. Taking Android system as the mobile terminal platform software, has a free open source,development ability, the design and development of geological disaster investigationinformation acquisition system based on the platform, which greatly improves the efficiency of geological hazard information collection, management.Based on introducing the Android platform development, structure, composition, combined with the design target of the system, carry out the system needs analysis, based on the field investigation of geologic disasters information collection, analysis, classification, contentacquisition system for determining the overall structure and function model of software, the design and implementation of the system interface based on Android platform, the system design interface, the design and Realization of each function module, finally through the analysis of the data structure and storage mode, establish the SQLite database. The system is mainly used for information input, information inquiry, field geological disasters,display of track length and area measurement, the specific function of the realization of thebasic map operation (including the map to enlarge, narrow, translation), GPS positioning, data acquisition (the acquisition, preservation, cancel), data query (query, query by type according to the time) motion track records, photographs, and the latitude and longitude is shown in thelower left-hand corner of the picture, recording (input, output, delete), camera (input, output.delete), measurement (length, area), graphics rendering, it will information collection, storage,management, text, sound, like in the form of comprehensive display, achieve integration of multimedia data and attribute data.
