Agreement assessment of NOAA/AVHRR NDVI with landsat TM NDVI for mapping burned forested areas
(2002)Meteorological satellites are appropriate for operational applications related to early warning, monitoring and damage assessment of forest fires. Environmental or resources satellites, with better spatial resolution than ... -
Assessment of crop damage using space remote sensing and GIS
(2002)This paper reports on a new Earth Observation ( EO) research field concerning the potential use of space remote sensing for the assessment of crop damage at the field level. Digital field (cadastral) maps were used in order ... -
Early cotton production assessment in Greece based on a combination of the drought Vegetation Condition Index (VCI) and the Bhalme and Mooley Drought Index (BMDI)
(2004)A new methodological approach is presented for quantifying the meteorological effects on cotton production during the growing season in Greece. The proposed Bhalme and Mooley Vegetation Condition Index (BMVCI) is based on ... -
Early cotton yield assessment by the use of the NOAA/AVHRR derived Vegetation Condition Index (VCI) in Greece
(2004)Satellite data can significantly contribute to agricultural monitoring. The reflected radiation, as recorded by satellite sensors, provides an indication of the type, density and condition of canopy. A widely used index ... -
Efficient segmentation of urban areas by the VIBI
(2012)Urban populations are expanding rapidly and so are cities. Remote sensing offers a convenient means of monitoring this expansion as it covers a period of 40 years in the case of the LANDSAT satellite. In some parts of the ... -
Examining urban sprawl in Europe using spatial metrics
(2015)Urbanisation is a global phenomenon with an important impact on the quality of human life. Europe has been widely affected by urbanisation. One of the main characteristics of urban growth is sprawl, a negative form of urban ... -
FEATURES OF FROST-AFFECTED AREAS FROM DIGITAL METEOSAT IR IMAGES
(1995)Frost is a natural hazard, which may cause significant damage to agriculture depending also on the phenological stage of the affected crops. In this paper, several features of the frost-affected areas are examined by using ... -
Forecasting of Remotely Sensed Daily Evapotranspiration Data Over Nile Delta Region, Egypt
(2013)Daily evapotranspiration is a major component in crops water consumption management plans. Consequently, forecasting of daily evapotranspiration is the keystone of any effective water resources management plans in fragile ... -
Geospatial predictive modelling of the Neolithic archaeological sites of Magnesia in Greece
(2011)Sources of heterogeneous geospatial data such as the elevation, the slope, the aspect, the water network and the current settlements related to the known Neolithic archaeological sites of Magnesia, are used in an attempt ... -
Monitoring cotton crop evapotranspiration based on satellite data
(2011)The water demand to meet seasonal and long-term water needs in Thessaly, central Greece, is related to historical semi-Arid conditions in the region, which is the main agricultural area of the country. In this paper ... -
Monitoring urban sprawl using simulated PROBA-V data
(2014)Urbanization proceeds currently at a rapid pace and the impact on natural ecosystems cannot be neglected. Consequently, it is important to be able to monitor the expansion of urban areas. Yet the process of extracting them ... -
Satellite image classification using granular neural networks
(2006)The increased synergy between neural networks (NN) and fuzzy sets has led to the introduction of granular neural networks (GNNs) that operate on granules of information, rather than information itself. The fact that ... -
Selecting landscape metrics as indicators of spatial heterogeneity-A comparison among Greek landscapes
(2014)This paper investigates the spatial heterogeneity of three landscapes along an altitudinal gradient and different human land use. The main aim was the identification of appropriate landscape indicators using different ... -
A spatial downscaling procedure of MODIS derived actual evapotranspiration using Landsat images at central Greece
(2013)In this study, the Surface Energy Balance Algorithm for Land (SEBAL) was used to derive daily actual evapotranspiration (ETa) distributions from Landsat and MODIS images separately. The study area is the Lake Karla basin ... -
Spatiotemporal classification of drought severity
(2011)The growing number and effectiveness of earth observation satellite systems, along with the increasing reliability of remote sensing methodologies and techniques, present a wide range of new capabilities in monitoring and ...
