Nuclear power industry had a great development in China in recent years and the environmental problems, such as thermal plume, has caused wide public concern. Taking the Hongyanhe nuclear power plant as example, this paper computed and achieved the sea surface temperature distribution with MODIS, HJ-1B and Landsat-8 thermal infrared data separately. These data were imaged in same time phase but different...
The territory knowledge plays a key role in the proper management and planning of many human activities. The relevance of land monitoring and mapping, that finally leads to quantify changes in land cover, is widely recognized as a key element in the study of global changes. Vegetation indices derived from satellite imagery are well correlated with those parameters that defines the crop yield's status;...
We developed a cost-effective monitoring tool to quantify forage production across landscapes,that are driven with satellite remote sensing data and calibrated with a statewide point dataset of peak forage production measurements. Our results showed that the satellite-derived annual forage production correlated well with contemporaneous in-situ forage measurements; it also captured spatial and temporal...
In coastal region, estuaries have dynamic conditions such as river discharge, tidal current, wave and sand ridge. These conditions generate suspended sediments processes in the estuary. Suspended sediment process can be used to explain reason for geological changes in the coastal area. To understand these processes, we use Geostationary Ocean Color Imager to monitor estuarine suspended sediments in...
Wave-based estimation of coastal bathymetry from satellite images is challenging because it often implies relying on ancillary data. Moreover, spatial resolution remains coarse compared to the image resolution because state-of-the-art wave analysis techniques decompose images into large-size patches. The method proposed here is based on adaptive wave tracing where the patch size depends on the wavelength...
To continue the groundwater monitoring networks in the plain areas for further demand of clean water resources, the groundwater exploration of mountainous regions becomes a crucial issue in Taiwan. In this study, 75 boreholes were drilled for conducting investigation by the integration of subsurface exploration technologies, including drilling, core inspection, geophysical logging, and hydraulic testing...
Water depth is necessary for shipping security, port and marine engineering construction and planning utilization of coastal zone and island. Traditional bathymetry methods can provide accurate measurements of the water depth. But remote sensing has characteristics such as speediness, synchronization, large area, high resolution and so on, and it can solve many problems which are hard to overcome...
The Algorithm Scientific Software Integration and System Transition Team (ASSISTT) at NESDIS STAR (National Environmental Satellite Data and Information Service, Center for Satellite Applications and Research) has designed, developed and implemented a Near Real-Time (NRT) processing system to process algorithms for scientists and other stakeholders. The system generates products using the STAR Algorithm...
This paper reports the findings on monitoring land subsidence in the south of Sydney, Australia, using data from ALOS-1 and ENVISAT satellites. Twenty-three L-band ALOS-1 PALSAR scenes acquired between 29 June 2007 and 07 January 2011 and twenty-six C-band ENVISAT ASAR image acquired between 09 July 2007 and 06 September 2010 are analysed in this research. Since the city of Wollongong and the town...
COSMO-SkyMed di Seconda generazione (CSG) Ground Segment is based on an interoperable and multi-mission design, allowing the exhibition of CSG services to external partners and the access through CSG to services belonging to other Earth Observation partners. Moreover CSG Ground Segment design allows supporting the cooperation by expansion through replication of UGS instances according to different...
COSMO-SkyMed (Constellation of Small satellites for Mediterranean basin Observation) is a fundamental, powerful asset to Earth Observation field, in which Italy plays a crucial role at world level. It is an Earth Observation Dual Use System (civil and military) conceived to fulfill both civilian and defense needs, enhancing international partnerships through its Interoperability, Expandability and...
Almost concurrent imagery from Landsat-5 and Radarsat-2 are examined separately and in combination to maximize the accuracy of a simple classification of a typical multi-use grassland region in western Canada. Almost all classifications were of sufficient accuracy to be used in an operational sense. Landsat seven band classification was the most accurate, but was deemed less likely to be useful as...
According to the need of an integration of satellite navigation and communication, the feedback information of terminal contains message information, picture information, voice information and navigation information, the satellite central station processing software needs to resolve, exchange and forward the communication information and resolve, storage, map matching and display processing the navigation...
The growth of the built environment is a global environmental change processes that can be measured and monitored with Earth Observation. That growth is expected to continue as populations continue to both increase and urbanize. The Global Human Settlement Layer (GHSL) project was set up to measure and monitor the global built up environment and its changes [1]. The GHSL layers presented herein are...
GaoFen (GF) series are the space-based system as part of the China High-Resolution Earth Observation System (CHEOS), which is established as one of the Chinese National Science and Technology Major Project. Three satellites of the series are already launched till now, and providing near-real time Earth observation with high spatial resolution of 1m and high spectral resolution reaching nanometer level...
In the paper we propose the methodology for solving the large scale classification and area estimation problems in the remote sensing domain on the basis of deep learning paradigm. It is based on a hierarchical model that includes self-organizing maps (SOM) for data preprocessing and segmentation (clustering), ensemble of multi-layer perceptrons (MLP) for data classification and heterogeneous data...
Desertification of semi-arid grasslands is a serious problem for economic development and ecological preservation. Using the Hunshandake Sandy Lands as an example, we present an overview of monitoring of land desertification using two different data sources including TM and MODIS data. The driving mechanisms of Hunshandake Sandy Land desertification are also discussed.
Monitoring snow distribution area plays an important role in researching climate change and energy exchange process. Chinese small satellite constellation (abbreviated HJ constellation) is special for environment and disaster continuously monitoring or forecasting. By using HJ-1B CCD and infrared data or only using its infrared data, it can construct NDSI (Normalized Difference Snow Index) or MNDSI...
GF-1 is the first satellite of this Chinese civilian remote sensing satellites series. This paper presents some typical applications on marine environmental monitoring with high resolution and wide swath satellite data, especial on the marine disaster monitoring such as oil spill, sea ice, and red tide. With these data, we can get the detailed information about different disaster.
Satellite remote sensing can provide repeat and detail observations, which has played an important role on the disaster management. Different with the existing satellites, GF—4, which works on the geosynchronous orbit and carry on a camera with 50 meter spatial resolution in visible and NIR bands, can give a continuous earth observation. It is the highest spatial resolution among the civil satellite...
