Remote sensing data sets frequently suffer from noise due to atmospheric conditions and instrument issues. This noise negatively affects the usability of these data sets and therefore noise reduction techniques are frequently used to reduce the impact of noise. A well-known remote sensing data set, MODIS Enhance Vegetation Index (EVI), measures the amount of vegetation (based on surface reflect...
modeling and prediction of land use/cover changes is an essential need for planning sustainable use of land in country like iran with its high level of changes in land uses and land covers. this study aimed to analyze the capability of ca markov prediction model and landsat satellite images for land use/cover change detection within the framework of âiran at 1404 prospectiveâ in esfarayen r...
In order to optimize the planning and management of natural resources and the environment, it is essential to know the status of land cover changes over the past decades. Modeling land cover change can provide valuable information for better understanding of this process, determining of effective factors and forecasting of regions subject to change. This study aimed to determine and simulate th...
Aims and Background: The present study purpose to investigate and predict the changes of metrics and Landscape change processes in the Gorganrood watershed in Golestan province. Methodology: First, land cover maps were prepared in 1990, 2000, 2010 and 2020. Then predict land cover changes for future conditions, under two scenarios (1) continuation of the current trend of change for 2040 and (...
Introduction Land use reflects the interactive characteristics of humans and the environment and describes how human exploitation works for one or more targets on the ground. Land use is usually defined on the basis of human use of the land, with an emphasis on the functional role of land in economic activities. Land use, which is associated with human activity, is undergoing change over time....
A ca. 1980 national-scale land-cover classification based on aerial photo interpretation was combined with 2000 AVHRR satellite imagery to derive land cover and land-cover change information for forest, urban, and agriculture categories over a seven-state region in the U.S. To derive useful land-cover change data using a heterogeneous dataset and to validate our results, we a) stratified the cl...
Urban is more sensitive to the change of land use/cover. The up-to-date information of land use/cover is very important for urban decision-making and sustainable development. Very high resolution satellite data are an alternative to monitor, update cartographic and geographic databases. In this paper, an object-oriented pre-parcel land use change detection approach integrating GIS and remote se...
