摘要
介绍了移动GIS的主要特点,分析了实现移动GIS的关键技术,介绍了基于Trimble GeoXT手持设备移动GIS软件的开发,其可实现Shp数据、XML数据和自定义二进制数据、遥感影像数据的浏览、空间查询等操作,通过设备端程序实现NTRIP网络协议与VRS服务器进行交互,实时获取差分数据修正GPS测绘精度,并实地测量进行了精度检验,阐述了该系统在城市勘测中如基础设施测量、执法巡查、城管部件数据检查、岩土工程勘察几个领域的应用。
This article describes the main features of mobile GIS,mobile GIS analysis of the key technologies to achieve introduced based on Trimble GeoXT handheld mobile GIS software development,which enables Shp data,XML data and custom binary data,remote sensing image data browsing,spatial queries and other operations,the device-side program to achieve NTRIP server network protocol to interact with the VRS,real time differential GPS correction data mapping accuracy,and precision of field measurements carried out tests described in the system in cities such as infrastructure survey measurement,enforcement inspections,the inspectors checked the data components,geotechnical engineering investigation of several fields.
