摘要:: 建筑物建(构)造特征信息获取的准确性及详实性直接影响房屋建筑物易损性模型的可靠性。建筑物信息采集过程覆盖范围广、数据详实程度要求高,需投入大量外业调查人员协同开展工作,耗时耗力且人工操作易出错,难以保障数据的准确性和实效性。针对上述问题,开发了以Android平台为移动终端,基于移动GIS的建筑物信息采集系统,并应用于地震灾害承灾体抽样详查工作。实践表明,该系统人机交互友好、操作简单方便,大幅度提高了建筑物信息采集效率及准确性,为开展房屋建筑物地震易损性分析建模提供了详实资料。

Abstract:: The accuracy and detail of the buildings' structural features decide the reliability of the buildings' vulnerability model,and affect the accuracy of the assessment of the earthquake-disaster risk.In the process of building-information collection,due to its wide coverage and high requirements for data details,a large number of field investigators are required.This is time-consuming and labor-consuming,and manual operation is prone to errors.It is difficult to ensure the accuracy and effectiveness of data.To solve these problems,we develop a building-information collection system based on Mobile GIS on Android platform,and this system has been successfully applied to the detailed survey of the earthquake-disaster bearing structures in the practice of the investigation of the earthquake-disaster risk in Sichuan Province.The practice proves that the system has friendly human-computer interaction,and makes the operation easy and convenient,greatly improving the efficiency and accuracy of building information collection.The system can provide detailed data for the analysis and modeling of the building's seismic vulnerability.
