获取城镇空间基础影像信息的低空遥感

Low Alititude Remote Sensing for Capturing Towns Space Basic Information

城镇是国家或地区的先进生产力、先进文化、先进思想的活动中心,是现代社会的主要结点。要实现对城市的现代化管理,促使其可持续发展,就得建设城镇信息系统。城镇影像信息是构筑城镇信息系统(数字城市)的核心数据。由超轻型飞机、热气飞艇、GPS接收机、航空摄影仪集成的低空遥感平台系统,用于获取城镇影像信息,经过数十次实践检验,技术性能指标能满足遥感应用和测绘成图精度要求。特别适用于中小城镇和大城市局部地区以及大型工程项目的大比例尺高分辨率摄影遥感。在具体运作中具有机动灵活、快速反应的能力,可操作性强,有较高性能价格比的优势,显示出良好的经济社会效益。

The image information of towns is the nuclear data of towns' information system,which is extremely important for their administration and development.For capturing these data,it has been built a low altitude remote sensing system using updated technologies,e.g. super-light airplane,hot-gas balloon,GPS receiver,aero-photographic camera etc. Practical testing showed that this system can yield precise data satisfactory for topography and cartography uses and is very efficient and suitable for large scale,high resolution photography remote sensing.
