Crop water status assessment in controlled environment using crop reflectance and temperature measurements
(2017)Crop water status is an important parameter for plant growth and yield performance in greenhouses. Thus, early detection of water stress is essential for efficient crop management. The dynamic response of plants to changes ... -
EUROPEAN LAND COVER MAPPING SYSTEMS FOR THE NATURAL AND URBAN ENVIRONMENT
(2014)Since 1985, European land cover mapping projects have been established to provide maps, a detailed and up-to-date portrayal of land cover from small to large scales. These programs offer technological and scientific support ... -
Feature evolution for classification of remotely sensed data
(2007)In a number of remote-sensing applications,. it is critical to decrease the dimensionality of the input in order to reduce the complexity and, hence, the processing time and possibly improve classification accuracy. In ... -
Granular neural networks for land use classification
(2005)Granulation of information is a new way to describe the increased complexity of natural phenomena. The lack of clear borders in nature calls for a more efficient way to process such data. Land use both in general but also ... -
Identification of the key variables that can be estimated using remote sensing data and needed for Water Footprint (WF) assessment
(2014)Accurate assessment of water use is an important issue in a globally changing climate and environment, where water is becoming a scarce but essential resource. The concept "?Water Footprint (WF) of a crop is defined as the ... -
Linking Distributed and Integrated Fiber-Optic Sensing
(2022)Distributed Acoustic Sensing (DAS) has become a popular method of observing seismic wavefields: backscattered pulses of light reveal strains or strain rates at any location along a fiber-optic cable. In contrast, a few ... -
Median Shift Lunar Correction for VIIRS
(2021)Visible Infrared Imaging Radiometer Suite (VIIRS) 24-h data are substantially affected by lunar illumination. A new method is proposed to correct this distortion and be able to form a consistent time series. The method has ... -
Monitoring land cover change detection with remote sensing methods in magnesia prefecture in Greece
(2000)The use of methodological tools of Remote Sensing such as spatial comparisons and classifications of satellite images results to the generation of thematic maps showing land cover change. This work originates from the ... -
Remote sensing and statistics for the investigation of uncontrolled landfill sites: A case study in Lesvos Island, Greece
(2004)Data collection for environmental sciences and, especially for land cover inventory, is an expensive and time-consuming procedure. On the other hand, the satellite remote sensing has been introduced with advantage for the ... -
Remotely Sensed Methodologies for Crop Water Availability and Requirements in Precision Farming of Vulnerable Agriculture
(2019)Agriculture is mainly impacted by water availability. Differences in climate conditions and the appearance of severe events, like droughts, has a significant imprint on local, regional and global agricultural productivity. ... -
Satellite Visible-Near Infrared Reflectance Correlates to Soil Nitrogen and Carbon Content in Three Fields of the Thessaly Plain (Greece)
(2013)Surface visible-near infrared (NIR) reflectance of bare soil by remote sensing devices has been used to infer topsoil properties such as organic matter, soil texture, water content, salinity, and crop residue cover. Spectral ... -
Seasonal cellular stress responses of commercially important invertebrates at different habitats of the North Aegean Sea
(2020)In many aquatic species, the negative effect of temperature variations has a significant impact on physiological performance since beyond Tp (upper pejus) and Tc (critical temperatures), according to the oxygen- and ... -
Sensitivity kernels for transmission fibre optics
(2022)Fibre-optic sensing based on transmission offer an alternative to scattering-based distributed acoustic sensing (DAS). The ability to interrogate fibres that are thousands of kilometres long opens opportunities for studies ... -
Space technologies for monitoring health and environmental impact of hydraulic fracturing
(2018)[No abstract available] -
Sustainable production zoning for agroclimatic classification using GIS and remote sensing
(2009)Agriculture is a primary productivity sector which is highly dependent on environmental conditions. The agroclimatic potential of agricultural areas has to be assessed in order to achieve sustainable and efficient use of ... -
Time series analysis of remotely sensed water quality parameters in arid environments, Saudi Arabia
(2021)The monitoring of inland water resources in arid environments is an essential element due to their fragility. Reliable prediction of the water quality parameters helps to control and manage the water resources in arid ... -
Use of hyperspectral/multispectral imaging in gastroenterology. Shedding some–different–light into the dark
(2019)Hyperspectral/Multispectral imaging (HSI/MSI) technologies are able to sample from tens to hundreds of spectral channels within the electromagnetic spectrum, exceeding the capabilities of human vision. These spectral ...
