本文主要阐述GPS-RTK测量技术在布设图根控制点中具体勘测实施情况。
本文根据常用的GPS水准高程拟合模型,利用测区的已知数据进行试算,并根据试验结果,从拟合的似大地水准面,已知点高程精度和GPS点大地高三方面,分析了GPS水准高程拟合精度,总结了提高拟合精度一些方法
虚拟参考站技术作为当今GPS技术发展的方向之一，结合本地的资源搭建具有特色的虚拟参考站系统，并对VRS系统管理与应用的经验进行了总结和对系统有待解决的问题进行了思考。
The expert knowledge has been widely used to improve the remotely sensed classification accuracy. Generally, the ex-pert classification system mainly depends on DEM and some thematic maps. The spatial
With remote sensing information products becoming increasingly varied and arguably improved, scientific applications of such products rely on their quality assessment. In an operational context such a
For centuries, explorers and scientists from different countries had made their own conclusions on the source of the Mekong. However, the geographic source of the Mekong is still arguable because of t
In the field of converting simulation surveying and traditional close range photogrammetry, it has been developed so far to survey objects by commercial digital camera and this technique is applied wi
In polar regions, cloud and underlying ice-snow areas are difficult to distinguish in satellite images because of their high albedo in the visible band and low surface temperature of ice-snow areas in
数字化地形地籍成图软件CASS7.0较以前版本有了进一步改进,但在日常制图应用中,有些程序与现实情况尚有一定差距。下述内容即为针对CASS7.0在制图方面的不足之处加以弥补,使CASS7.0更贴近具体要求,更能便捷地简化操作。
