The reasons for the poor performance of conventional, per-pixel classification algorithms applied to satellite sensor images of urban areas are examined. It is argued that standard algorithms are poorly adapted to distinguish between different urban land-use categories, particularly in high spatial resolution images, due to the complex spatial pattern of spectrally distinct land-cover types in ...

Remote sensing has been considered a low-cost, large-area coverage forest information resource ideally suited to broad-scale forest inventory objectives. The objective of this study is to determine stand type parameters such as crown closure, development stage and stand types, and land cover obtained from Landsat 7 ETM image and forest cover type map (stand type map). The research also focuses ...

during the time, land cover and as a result land use patterns go through fundamental changes and human factors can have the most important role in this process. knowing these changes could be of great help to the future management of this region. according to this, the main purpose of this study is to monitor the land use-cover changes in the hamedan province area during the three recent decade...

The objective of this research was to assess vulnerable soil erosion risk with qualitative approach using GIS in Ankara-Guvenc Basin. The study area is located about 44 km north of Ankara and covers 17.5 km2. The selected theme layers of this model include topographic factor, soil factors (depth, texture, impermeable horizon) and land use. Slope layer and land use-land cover data were prepared ...

For an optimum use of natural resources in the sustainable development trend, there is a need to identify ecological resources in the shortest period of time and minimum possible cost. In this article, we aimed Management ecosystem by Assessment of plant covers changes at Taleghan Township in a twenty year period. Percentage of landscape and number of patch were among the metrics that were calc...

Quantitative methods for mapping sub-pixel land cover fractions are gaining increasing attention, particularly with regard to upcoming hyperspectral satellite missions. We evaluated five advanced regression algorithms combined with synthetically mixed training data for quantifying urban land cover from HyMap data at 3.6 and 9 m spatial resolution. Methods included support vector regression (SVR...

It has been widely asserted that the morphology of urban areas is a result of the interactions of urban function and urban form. This has led a number of studies to postulate, either explicitly or implicitly, that a mapping exists between the physical form (land cover) of the urban fabric and its corresponding function and activity (land use), although relatively little quantitative evidence ha...

This paper is concerned with data and classifications that confuse the concepts of land cover and land use. Conceptual confusion is problematic for data integration and modelling. This has resulted in calls for the separation of land use and land cover from the global land monitoring community. Text mining approaches are combined with social network analyses as a method for unravelling the diff...
