移动端土地资源外业调查系统技术研究

Research on Field Survey System of Land Resources on Mobile Terminals

为解决土地资源外业调查效率低、成果质量难以控制、作业智能化不足等问题,利用3S、移动互联、4G/5G通信等技术,基于智能移动终端设备,探讨了土地资源外业调查流程,阐述了智能草图绘制技术、移动地图动态标注技术以及防篡改加密技术3种关键技术,搭建了移动端土地资源外业调查系统,实现了土地资源调查成果的展示、查询和统计、土地调查取证、草图绘制、辅助工具等功能,使土地资源外业调查工作更加科学化和智能化。

To solve the problems of land resources survey such as low efficiency,difficulty in result quality control,insufficiency in intelligent operation,this paper proposes to use the 3S,mobile Internet and 4G/5G communication technology,based on the intelligent mobile terminal equipment,discusses the field survey process of land resources,expounds the intelligent sketch mapping technology,the mobile dynamic map labelling technology,and tamper-proof encryption technology.The field survey system of land resources on mobile terminals has been built to realize the functions of display,query and statistics,local survey and evidence collection,sketch mapping and auxiliary tools of land resources survey results,making the field survey of land resources more scientific and intelligent.
