湖泊变化是气候变化的指示器.为探索利用单一短时间尺度的卫星水位数据源估算长时间序列的湖泊水量变化的可行性,本文利用短时间尺度(2016—2018年) Sentinel-3A合成孔径雷达高度计(SRAL)作为唯一卫星水位数据源,以藏北高原内陆湖泊当惹雍错为例,结合基于Landsat光学遥感数据提取的1988—2018年的湖泊面积,综合分析2016—2018年间的非结冰期遥感湖泊面积与遥感湖泊水位变化...
Overarching goal of this paper was to evaluate automated and semi-automated methods of mapping wetlands using Landsat ETM+ and SRTM data. Automated methods consisted of: (a) slope derived from SRTM, (...

This paper proposes a change detection analysis method based on multitemporal LANDSAT satellite data, presenting a study performed on the Lama San Giorgio (Bari, Italy) river basin area. Based o...
The snowmelt-runoff model developed by Martinec (1975) has been used to simulate daily streamflow on the 228 km2 Dinwoody Creek basin in Wyoming, U.S.A. using snowcover extent from Landsat and conve...
The snow cover is an important parameter for water run-off prediction in high mountain areas. At present its seasonal changes can be monitored regularly by satellite. The paper presents a new method...
Landsat-5 Thematic Mapper (TM) reflectances recorded i May 1989 from a mountainous catchment at Kvikne, Norway, are analyzed and compared with simultaneously measured in situ albedo. The satellite-r...
Determining land-cover characteristics of large watersheds for use in hydrologic models has been enhanced by application of remotely sensed data and the technologies used to interpret them. The object...
摘要:利用2000年的Landsat ETM数据,首次采用全数字化遥感定量方法对鄱阳湖湿生植被的生物量及其分布进行调查研究。首先,用该时相卫星数据制作假彩色合成图象,以该图象为主要依据之一,设计了野外生物量采样路线与样点,并在地形图和GPS的帮助下,实时地开展了湿生植被生物量的野外实地采样。然后,在室内将采样点坐标和Landsat ETM图象坐标进行几何纠正和匹配,将坐...
