The Ziyuan-3 (ZY-3) satellite, as the first civilian high resolution surveying and mapping satellite in China, has a very important role in national 1 : 50,000 stereo mapping project. High...
ZY-3 is the first civilian high resolution stereo mapping satellite, which has been launched on 9th, Jan, 2012. The aim of ZY-3 satellite is to obtain high resolution stereo images and support the 1:5...
To investigate the forest height estimation potential and performance of different observation periods GLAS data in temperate region, this study uses the Northeast of China as test site. USFS FIA styl...
Methods of estimating stemwood volume from ICESat/ GLAS lidar waveforms are explored for a mixed temperate forest, the Forest of Dean, Gloucestershire, UK. Previous methods have used maximum canopy he...
Our previous studies using airborne lidar data have shown that the tree height indices derived from the GLAS and LVIS waveforms were highly correlated. The quartile waveform energy heights derived fr...
星载激光测高系统亚毫弧量级的发散角和冰层表面几乎没有穿透效应的优势使其非常适于监测南北极冰盖变化。利用GLAS激光测高卫星的高程数据,通过交叉和重复点方法分析2003~2009年3月格陵兰2 000 m以上区域冰盖高程变化,并改进了交叉点计算方法,使其适合纬度跨度较大的格陵兰地区。经过粗差剔除和时序解算,研究结果表明,该区域7年间冰盖高程年均变化+3.80 cm/年,中误差0.91 cm,呈缓慢增...
The Geoscience Laser Altimeter System aboard NASA’s Ice, Cloud and land Elevation Satellite will record the height distribution of laser energy reflected from surfaces within 70 m diameter footprints....
