摘要:
传统上,区域野外地质灾害调查主要是利用罗盘、地质锤、放大镜等工具进行等在野外完成,日后专业人员获取这些灾害点的相关原始数据需要从资料室的资料柜里进行查找并整理后进行统计分析,这种工作模式不利于数据共享与管理,也不适应"数字国土"工程的建设节奏,因此,基于3S技术建立一套集野外数字采集、成图、分析以及数据输出一体化的地质灾害野外调查数字采集系统是解决上述问题的关键所在。本文从需求分析着手,从系统构成、野外数据采集模型、实体模型、系统功能等方面对系统的构建进行探讨研究,最后结合本文的设计,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。
Abstract:
In the tradition,the region open country geology disaster investigation mainly uses tools to complete in the open country.In the future,if the specialist want to gain primary data about the disaster,they need data from material cabinets to reorganize and analyze them.This kind of working pattern will not favor data sharing and the management.Also will not adapt the construction rhythm of "the digital national territory" project.Therefore,based on the 3S technology,to establish a set of geological disaster open country investigation numeral gathering system integrating open country numeral gathering,producing chart,the analysis and the data output integration is the key to solve above question.This paper begins from the demand analysis,and to the system construction carries on discussion research from several aspects such as system constitution,field data gathering model,entity model and system function.Finally,uniting the design and using domestic product embedded GIS software MAPGIS,has realized a set of geological disaster open country investigation numeral gathering system integrating the fiele data organization,issuing gathered background document,collecting gathered data integration.
