Application of the Sebs Water Balance Model in Estimating Daily Evapotranspiration and Evaporative Fraction from Remote Sensing Data Over the Nile Delta
(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 ... -
Climate change effects on drought severity
(2008)This paper evaluates climate change effects on drought severity in the region of Thessaly, Greece. The Standardized Precipitation Index (SPI) has been used for estimation of drought severity. A geographical information ... -
A Comparison between Variable Deficit Irrigation and Farmers’ Irrigation Practices under Three Fertilization Levels in Cotton Yield (Gossypium hirsutum L.) Using Precision Agriculture, Remote Sensing, Soil Analyses, and Crop Growth Modeling
(2022)The major global challenge for the coming decades will be increasing crop production with less water consumption. Precision agriculture (PA) and variable deficit irrigation (VDI) are management strategies that help farmers ... -
A cost-effective method for tranquility mapping using open environmental data
(2020)In this study, we propose a cost-effective method for tranquillity mapping using multi-criteria analysis and open geospatial data. We apply this method in an extended zone around a major Greek highway trespassing areas of ... -
Creation of a remote sensing unmanned aerial system (UAS) for precision agriculture and related mapping applications
(2013)Our goal is to create a fully autonomous airborne remote sensing platform, for the production of various vegetation indices to determine growth, development, yield crop and provide considerable information in real time and ... -
Defining a safe design distance from tectonic structures in urban and regional planning
(2020)This study proposed the neotectonics application to urban and regional planning in order to identify high-risk areas by determining fault-related impact zones. This problem requires urgent attention and prompt action because ... -
Determination of fire risk to assist fire management for insular areas: the case of a small Greek island
(2019)Forest fire risk estimation constitutes an essential process to prevent high-intensity fires which are associated with severe implications to the natural and cultural environment. The primary aim of this research was to ... -
An eco-efficient and economical optimum evaluation technique for the forest road networks: the case of the mountainous forest of Metsovo, Greece
(2018)The sustainable forest management can be achieved only through environmentally sound and economically efficient and feasible forest road networks and transportation systems that can potentially improve the multi-functional ... -
Effects of student participation in an online learning community on environmental education: a Greek case study
(2011)The aim of the present study was: (a) the creation of an Online Learning Community (OLC) for the implementation of an environmental education (EE) project in secondary education, and (b) the investigation of the potential ... -
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 ... -
Evaluating the services and facilities of European cities using crowdsourced place data
(2018)Statistics about citizen satisfaction regarding urban facilities and services are required for governing urban areas. Such statistics are often unavailable or outdated. At times, existing statistics are irrelevant to the ... -
Exploring spatial data through computational intelligence: a joint perspective
(2005)The dramatic increase in geospatial data occasioned by developments in digital mapping, remote sensing, IT, and widespread generalization of Geographic Information Systems (GIS), emphasises the importance of exploring new ... -
Factors affecting the distribution of potentially toxic elements in surface soils around an industrialized area of northwestern Greece
(2012)In order to investigate the factors influencing the distribution of 32 potentially toxic elements in the Ptolemais-Kozani basin, northwestern Greece, 38 soil samples were collected and analyzed. Concentrations of Al, Ca, ... -
First evidence of Leishmania infection in European brown hare (Lepus europaeus) in Greece: GIS analysis and phylogenetic position within the Leishmania spp
(2015)Although the existence of a sylvatic transmission cycle of Leishmania spp., independent from the domestic cycle, has been proposed, data are scarce on Leishmania infection in wild mammals in Greece. In this study, we aimed ... -
Formulation of the conceptual model for the tectonic geomorphological evolution of an area: Five main rivers of Greece as a case study
(2018)This paper associates the tectonic conditions of five rivers (integrated drainage networks) in northwestern Greece, for the purpose of formulating the conceptual model of its tectonic and geomorphological evolution. The ... -
A geographical information system managing geotechnical data for Athens (Greece) and its use for automated seismic microzonation
(2008)This article presents a geographical information system (GIS) which manages geotechnical data obtained from detailed geotechnical surveys as well as from in situ observations in Athens, Greece. Thoroughly examined data ... -
Geomorphological analysis of Scopia catchment (Central Greece), using DEM data and GIS
