基于Android的GIS县域遥感监测系统

为满足县域遥感监测对智能化、信息化的需求,以河北省廊坊市为研究区,采用C/S架构,建立基于Android的GIS县域遥感监测系统。系统主要包括注册登录、地图服务、专题信息查询和统计分析等四大功能模块。注册登录模块采用SQLite数据库开发,用户权限依行政区划等级配置;地图服务模块使用ArcGIS Runtime SDK for Android工具包实现,具有地图展示、图层添加、实时定位、地图截图、坐标转换、空间量测等功能;专题信息查询模块通过ArcGIS Server发布的服务获取数据并添加OperationLayers业务图层实现,能够查询和显示专题信息的空间分布状况;统计分析模块使用MPAndroidChart开源图表库实现,具备县域遥感资源监测信息查询、统计分析、可视化图表构建和动态显示功能。系统可为农业、林业和环保等相关部门提供技术和辅助决策支持。

Remote Sensing Monitoring System of GIS County Area Based on Android

In order to satisfy the needs of informatization,digitalization and intellectualization of county remote sensing monitoring,Langfang city,Hebei province is taken as the research area and C/S architecture is adopted to establish a GIS county remote sensing monitoring system based on Android,which consists of four function modules,registered login,map service,thematic information query and statistical analysis.The registered login module is developed by SQLite database,and users’rights are allocated according to administrative divisions.The map service module is implemented by using the ArcGIS Runtime SDK for Android development kit,which can realize the function of map zoom in and out,adding layers,real-time positioning,map screenshots,coordinate transformation and spatial measurement.The thematic information query module obtains data through the service published by ArcGIS Server and adds the OperationLayers business layer implementation,which can query and display the spatial distribution of the thematic information.The statistical analysis module is implemented by MPAndroidChart chart library,which has the function of county remote sensing resource monitoring information query,statistical analysis,creating visual Charts and dynamic display.The system can provide decision and technical support for relevant departments such as agriculture department,forestry department and environment protecting department.
