热红外遥感在研究地气相互作用方面有独特优势,但因受云的影响无法获得时空连续信息。近年来,可见光与微波遥感已被成功应用于计算全球地表蒸发,但是热红外还未被应用于估算全球蒸发。如何获得时空连续的地气间水分交换信息,是当前热红外遥感研究地气相互作用过程时遇到的“卡脖子”问题。国际上有观点认为基于能量平衡的热红外方法无法准确得到地表的蒸发,主要原因是蒸散发的估算对地气相互作用的水热传输阻力较敏感,并且受云...
光盖山-迭山南麓断裂是东昆仑断裂向西秦岭北缘断裂应变转换的主干断裂之一,受森林覆盖、自然和人为改造、交通不便等多因素的影响,光盖山-迭山南麓断裂的几何特征一直不明确。文中收集多种类型、分辨率、时相的遥感图像并在Envi5.2平台下进行增强处理,然后对光盖山-迭山南麓断裂进行目视解译,在此基础上对重点段进行野外考察,通过一系列断错地貌和断层剖面等地质地貌现象验证解译结果,最后得到光盖山-迭山南麓断裂...
The Indian part of Kailash Sacred Landscape (KSL) is prone to flash floods, landslides and forest fires leading to various environmental and socio-economic problems. This study aims to identify areas ...
Drought intensifies stress on the water resource which is already in a critical condition due to rapid urbanization and population growth thus, affecting people, economy, and environment. The drought ...
Evapotranspiration (ET) is an essential element of the hydrological cycle and plays a significant role in regional and global climate through the hydrological circulation. Estimation and monitoring of...
Remote Sensing is a very reliable and expeditious technique for assessment and mapping of surface waterlogged areas. In this study band ratio based NDWI index (Normalized Difference Water Index) was u...
In this paper, we propose a spectral-spatial feature extraction framework based on deep learning (DL) for hyperspectral image (HSI) classification. In this framework, the variational autoencoder (VAE)...
SMAP project released a new enhanced high-resolution (3km) soil moisture active-passive product. This product is obtained by combining the SMAP radiometer data and the Sentinel-1A and -1B Synthetic Ap...
In this paper, we propose a software architecture for a feature extraction tool which is suitable for automatic extraction of sparse features from large remote sensing data capable of using higher ord...
Produced by radar data or stereo remote sensing image pairs, global DEM datasets are one of the most important types for DEM data. Relative error relates to surface quality created by DEM data, so it ...
In view of the fact that the deep convolutional neural network has stronger ability of feature learning and feature expression, an exploratory research is done on feature extraction and classification...
Vegetation is an important part of the terrestrial ecosystem. It plays an important role in the energy and material exchange of the ground-atmosphere system and is a key part of the global carbon cycl...
Urban lakes are important natural, scenic and pattern attractions of the city, and they are potential development resources as well. However, lots of urban lakes in China have been shrunk significantl...
The availability and accessibility of remote sensing (RS) data, cloud processing platforms and provided information products and services has increased the size and diversity of the RS user community....
