基于ArcGIS for Android和Spatialite的离线国土资源“一张图”系统研究与实现

随着以手机、平板电脑等为代表的移动设备的广泛使用,移动端系统开发技术的日趋成熟,移动端上的“一张图”应用如雨后春笋般涌现,但现在的“一张图”采用在线的方式,访问发布的各种地图服务。而国土资源规划管理中许多工作区域在偏远或网络信号差的地区,加上因数据涉密不能运行在互联网上,当前的方式已然无法满足当前工作需要。因此,本文基于ArcGIS for Android和Spatialite技术,研究、实现一种离线移动端国土资源“一张图”系统,并用于铜仁市国土资源管理调查工作中。

Research and Implementation of Offline Land Resources "One Map" System Based on ArcGIS for Android and Spatialite

With the widespread use of mobile devices such as mobile phones and tablet computers,mobile terminal system development technology is becoming more and more mature."One Map"applications on the mobile terminal have sprung up.The current"One Map"is an online way to access various map services published.However,many work areas in land and resources planning management are in remote areas or areas with poor network signals.In addition,because of data confidentiality,they cannot run on the Internet,the current method can no longer meet the current work needs.Therefore,based on ArcGIS for Android and Spatialite technology,this paper studies and implements an offline mobile terminal"One Map"system,which is used in the survey of land and resources management in Tongren City.
