Application of the Sebs Water Balance Model in Estimating Daily Evapotranspiration and Evaporative Fraction from Remote Sensing Data Over the Nile Delta
Elhag, M.; Psilovikos, A.; Manakos, I.; Perakis, K. (2011)Estimation of evapotranspiration is always a major component in water resources management. The reliable estimation of daily evapotranspiration supports decision makers to review the current land use practices in terms of ... -
Assessment of crop damage using space remote sensing and GIS
Silleos, N.; Perakis, K.; Petsanis, G. (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 ... -
DESIGN OF AN ELECTRODIALYSIS BRACKISH WATER DESALINATION PLANT USING RENEWABLE RESOURCES BASED ON STATISTICAL ANALYSIS OF CLIMATE CONDITIONS
Tsiakis, P.; Manakou, V.; Perakis, K.; Kungolos, A. (2012)The interest in desalination methods has always been high and recently renewed due to the shortage of water in many remote areas and the diminishing natural fresh water resources. With almost 97% of the total water being ... -
Efficient segmentation of urban areas by the VIBI
Stathakis, D.; Perakis, K.; Savin, I. (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 ... -
EUROPEAN LAND COVER MAPPING SYSTEMS FOR THE NATURAL AND URBAN ENVIRONMENT
Moysiadis, A.; Perakis, K. (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
Stathakis, D.; Perakis, K. (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 ... -
GEOCLOUDS FOR ENVIRONMENTAL MANAGEMENT
Evangelidis, K.; Ntouros, K.; Papatheodorou, K.; Konstantinidis, A.; Perakis, K. (2014)Environmental monitoring and management are multidisciplinary tasks which require a continuous and close cooperation among involved stakeholders from various public entities, based in different locations. This fact poses ... -

Perakis, K.; Kyrimis, K.; Kungolos, A. (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
Perakis, K.; Malliaros, D.; Soulakellis, N.; Silleos, G.; Kungolos, A. (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 ... -
Statistical evaluation of PCDD/F emission data during solid waste combustion by fuzzy clustering techniques
Samaras, P.; Kungolos, A.; Karakasidis, T.; Georgiou, D.; Perakis, K. (2001)An advanced statistical analysis technique using the fuzzy clustering method was employed in this work, for the evaluation of PCDD/F emissions during solid waste combustion. In addition, this technique was applied for the ... -
Vegetation indices: Advances made in biomass estimation and vegetation monitoring in the last 30 years
Silleos, N. G.; Alexandridis, T. K.; Gitas, I. Z.; Perakis, K. (2006)During the last 30 years Vegetation Indices (VI) have been extensively used for tracing and monitoring vegetation conditions, such as health, growth levels, production, water and nutrients stress, etc. In this paper the ...
