Remote sensing techniques and spatial data analysis through Geographic Information Systems (GIS) have been jointly applied in a mineral exploration context to identify gold-rich potential areas in SE Spain. Results conŽ rm the usefulness of this integrated methodological approach as an eVective tool to assess mineral potential in the studied region. Satellite and airborne image analysis have oV...

The aim of this study is to determine runoff depth of the Van Lake basin by using remote sensing and geographic information system (GIS) integration. While determining the results we used various data sets such as Landsat satellite image, 1:25000 standard topographic map, and soil map data. Standard 1:25000 topographic maps were used to derive digital elevation model. Sub-basin area and physica...

given the critical role played by urban green spaces and the emergence of remote sensing as avaluable natural resource management tool, this study sought to identify trends in green spaces within thecontext of south africa’s transition period (1990 - 2000). using the city of port elizabeth as a case study, threesets of landsat - 5 thematic mapper images (1990, 1995 and 2000) were geo-processed,...

Locust outbreaks occur on all continents except Antarctica and can affect the livelihoods of one in 10 people on Earth. To prevent economic and environmental losses, locust breeding areas should be periodically monitored, and an early detection-early response strategy should be in place. Traditional, ground survey methods are inefficient to adequately address the large spatial scale of the locu...

The most widely known remote-sensing data are satellite images (typically LANDSAT or other visible imagery), which are used in the geosciences for a multitude of applications, including landuse, urbanization, sea-ice expansion, to name only a few. Commonly, these remote-sensing data are analyzed with the help of commercial software systems (eg. ENVI, ERDAS-IMAGINE). Analysis methods employ the ...

The progress of information technology (IT) and the need for global distribution of geospatial information and remotely sensed imagery create strong needs for web-based geographic information systems (GIS) and remote sensing facilities (Tsou and Buttenfield, 1998; 2002; Limp, 2001). This paper introduces a webbased remote sensing application that can provide advanced image comparison and proces...

GIS data and methods have the potential to answer questions concerning agriculture that were too complex to even consider formulating until quite recently. Unfortunately for researchers trying to publish findings ranging from the reasons for spatial patterns in the distribution of weeds to options for the placement of straw-based biofuel refineries, the publication process is fraught with extra...

In this study which is based on the information taken from the map of Soil Conservation and Management Master Plan of Turkey published by the Ministry of Agriculture Forestry and Rural Affairs in 1987, all major soil groups were digitized and stored in a computer. After transferring process, the data in a GIS software have been used with different data such as main characteristics of the soils,...

abstract evapotranspiration (et) determination is a key factor for irrigation scheduling, water balance, irrigation system design and management and crop yields simulation. therefore many scientists have tried to estimate evapotranspiration in different spatial and temporal scales. remote sensing is a one of new technique in estimation of et in regional scales. so, in this study it’s tried to e...

This article describes the results of a training course for teachers, "Fundamentals Remote Sensing: History and Practice", which was organized by "GIS Sensing" Laboratory National Center "Junior Academy Sciences Ukraine." The discusses preconditions organization ways remote sensing data application in educational process. It also provides examples individual research participants, were presente...
