urbanization and population growth along with an increase in the environmental pollution resulting from human activities which have dramatically changed the green space and land cover have been key factors in the sustainable development of land and the management of land use. to collect reliable data required for providing land cover maps as well as for investigating the environment, remote sen...

In Sweden, drainage and the construction of water infrastructure have influenced agriculture in last few centuries both positively negatively. Recently, a trend has set where wetlands are constructed to retain water, reduce nutrients enhance biodiversity. This study aimed use remote sensing techniques landscape retention over time. this pilot study, structures Gotland (57°28′35.0′′N18°29′ 13.9′...

Abstract Remote-sensing satellite images provided rapid and continuous spectral spatial information of the land surface in Sougia River catchment by identifying major changes that have taken place over 20 years (1995–2015). Vegetation indices (VIs) normalized difference vegetation index (NDVI), enhanced (EVI) leaf area were derived for monitoring mapping variations cover. The quantified decreas...

Contemporary research has shown that remote sensing techniques can be used for estimating live fuel moisture content (FMC) from space. These remote sensing based live FMC measurements must conform to some accuracy requirements to be of any practical use in fire behavior predictions. This paper thus investigates the potential errors in live FMC estimations using two simple established techniques...

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,...
