地质灾害野外调查数据采集系统数据模型研究

文章从需求分析着手,利用3S技术、结合现代化的掌上电脑,从系统构成、野外数据采集模型、实体模型等方面对系统的构建进行了探讨研究。最后结合设计,利用国产的嵌入式GIS软件MAPGIS,实现了集野外数据的组织、采集背景文件的发布、采集数据收集一体化工作流程的地质灾害野外数据数字采集系统。

Data model of digital data gathering system for geological disaster investigation

In the traditional geological disaster investigation patterns,all data gathering mainly depends on investigators in the field by the tools,such as the compass,geological hammer and magnifying glass and soon.All information was recorded by the paper medium,which has brought difficulty for the data management and data sharing,and does not conform nowadays development tendency of social information.Using the 3S technology with modern computers in palm,to establish a set of automatic highly digital data gathering system for disaster investigation is the key to solve this question.A study based on the demand analysis about system constitution,data gathering model,embodiment model,system function was made in this paper.With the design method and using the domestic inserted type GIS software,MAPGIS,it is realized that the integrated work flows system of data organizing,the gathering background document issuing,data gathering integration,i.e.Digital Data Gathering System for Geological Disaster Investigation.
