Land use is a dynamic phenomenon that changes with time and space due to anthropogenic pressure and development. Evaluating the existing land use and its periodic change is useful for urban planners, policy makers and natural resource managers. Land use and land cover changes in Mekelle City, Ethiopia (north east Africa) over a period of 25 years was studied using remotely sensed data. Multi te...
Integrating malaria data into a decision support system (DSS) using Geographic Information System (GIS) and remote sensing tool can provide timely information and decision makers get prepared to make better and faster decisions which can reduce the damage and minimize the loss caused. This paper attempted to asses and produce maps of malaria prone areas including the most important natural fact...
land use mapping using fuzzy classification: case study in three catchment areas in hamedan province
land cover mapping is important for many planning and management activities. today, satellite images and remote sensing techniques are extensively used in all sectors including agriculture and natural resources because they provide updated data and high analyzing abilities. in this study, in order to produce land cover map for the northern part of hamedan province , digital satellite data irsp6...
This paper describes first results of a land cover / land use (LCLU) classification of Germany, developed at the German Remote Sensing Data Center (DLR-DFD). The automated, yearly updated product is based on MERIS level 2 full resolution data. The classification procedure consists of two main steps, namely a multispectral and a multitemporal analysis. The legend of the LCLU map is defined accor...
Application geographic information systems (GISs) and remote sensing integration to provide determination of runoff from watershed has performed increasingly attention in recent years. In this study, Natural Resources Conservation Service Curve Number (NRCS-CN) method was used to estimate Curve number according to the factors of hydrological soil group, land use, land treatment, drainage basin ...
the aim of this study is to investigate underground water quality parameters in gorganrud river basin and their connection with aboveground conditions using gis and artificial neural networks. in order to prepare a land use map of the area, liss iii image of irs satellite of the year 2008 was used in a maximum likelihood classification. the results revealed that there was a significant correlat...
nowadays because of various factors, including inappropriate land use, and indiscriminate exploitation of water resources, soil and vegetation, wide areas of the country were exposed to destruction of lands and desertification. therefore dealing with this situation requires a comprehensive land use program (water and land) and appropriate environment potency. the study area is patom district of...
Sand and gravel are important raw materials which are needed for many civil engineering projects. Due to economic reasons, sand and gravel pits are frequently located in the periphery of metropolitan areas which are often subject to competing land-use interests. As a contribution to land-use conflict solving, the Analytic Hierarchy Process (AHP) is applied within a Geo-Information-System (GIS) ...
This paper examines the application of object-orientated processing and artificial intelligence techniques to high spatial resolution satellite sensor images for urban land-use monitoring. Although these techniques have been applied to aerial photography for some time, their use in the analysis of digital images acquired by satellite sensors is much less well developed. Within this study, a two...
Scientists need a better and larger set of tools to validate land-use change models, because it is essential to know a model’s prediction accuracy. This paper describes how to use the relative operating characteristic (ROC) as a quantitative measurement to validate a land-cover change model. Typically, a crucial component of a spatially explicit simulation model of land-cover change is a map of...
