The Application of GPS in South China Forest

摘要: 应用ＭａｇｅｌｌａｎＰｒｏｍａｒｘＸ－ＣＭＧＰＳ接收机在广东省新丰县小镇镇林区进行野外样地定位等试验，结果表明，林冠郁闭度、天线类型、天线高度对卫星信号的接收均有一定的影响；ＧＰＳ在杉木林中基本能定位；ＧＰＳ与ＴＭ卫星影象套合误差小于一上象元；差分ＧＰＳ定位技术在南方山区林业调查应用是可行的。

Abstract: An orientational experiment is made, using Magellen Promarx X cm GPS, in the forest in Xiaozhen District, Xinfeng County, Guangdong Province. Results are as follows: the satellite's signal receiving will be influenced by crown coverage, the GPS antenna type and the antenna height. The orientation using GPS can be carried out in Chinese fir forest. The error which GPS datum supposed TM images is less than one pixel. DGPS method can be applied to forest survey in mountainous area in South China.
