The usefulness and acceptance of geoinformation systems (GIS) mainly depend on the quality of the underlying geodata. The aim of this paper is to introduce an approach for the verification of cropland and grassland objects in a GIS. The approach compares the GIS objects with data derived from high resolution remote sensing imagery using image analysis techniques. Textural, structural, and radio...

Remote Sensing, an open access journal (http://www.mdpi.com/journal/remotesensing) has grown at rapid pace since its first publication five years ago, and has acquired a strong reputation. It is a " pathfinder " being the first open access journal in remote sensing. For those academics who were used to waiting a year or two for their peer-reviewed scientific work to be reviewed, revised, edited...

New digital systems for the processing of photogrammetric and remote sensing images have led to new approaches to Ž . information extraction for mapping and Geographic Information System GIS applications, with the expectation that data can become more readily available at a lower cost and with greater currency. Demands for mapping and GIS data are increasing as well for environmental assessment...

the aim of this study is prospecting of iron and manganese in the balvard 1:100000 sheet which is situated in sanandaj - sirjan structural zone utilizing index overlay and fuzzy logic methods in the gis. in this study, the layers for integration, alterations, geological, geophysical, geochemical and structural data based on stream sediments, airborne magnetometeric and remote sensing studies. b...

soil is one of the most important natural resources covering a large area of the land surface. soil plays a vital role in biosphere processes, such as energy balance, hydrology, biochemistry, and biological productivity. it supports plants that supply foods, fibers, drugs, and some other human needs. conversely, desert regions include about one third of earth lands and these regions have increa...

Quality evaluation of urban environment is an integral part of efficient urban environment planning and management. The development of fuzzy set theory (FST) and the introduction of FST to the urban study field attempts to incorporate the gradual variation and avoid loss of information. Urban environmental quality assessment pertain to interpretation and forecast of the urban environmental qual...
