Since the 1990s, Morocco’s agriculture has been characterized by co-existence and transformation of both modern traditional smallholder systems. In Atlas Mountains, effects rural–urban have led to intensified irrigated in some agricultural areas, while others were abandoned. To better understand these effects, this study aimed at (1) analyzing land use cover (LULC) changes, (2) assessing struct...

Land cover derived from remotely sensed products is an important input to a number of different global, regional and national scale applications including resource assessments and economic land use models. During the last decade three global land cover datasets have been created, i.e. the GLC-2000, MODIS and GlobCover, but comparison studies have shown that there are large spatial discrepancies...

1:50000 land cover classification and mapping program is an important part of the mapping project in western China, which is organized by Chinese State Bureau of Surveying and Mapping Organization and will finish 5032 maps at scale of 1:50000 until 2010. With an average altitude of 4400 m, Sanjiangyuan mapping district is located at the center of the Qinghai-Tibet Plateau. Because of complicate...

the objective of this study was to assess the relationship betweenvegetation, landform and physicochemical properties of soil. at the first terrainmap unit were provided using the landsat thematic mapper (tm) satellite images,aerial photograph, topographical and geology map. field sampling was done in therepresentative area using plot sampling. 104 plots 100 m2 were sampled in eachplot landform...

Urban development has enlarged the modification of natural resources and has changed land use and land cover patterns. Urbanization is a process of increase of modernization system which modifies the socioeconomic activities and revolutionizes the land use practice according to time frame. Due to the proximate and underlying causes, land use and land cover change has become the main challenge o...

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...

Land cover plays a significant role in the earth system science, which reflects the influence of human activities and environmental changes (Sellers et al., 1997; IGBP, 1990; Aspinall et al, 2004). In China, Many land use/cover maps can be used in recent years derived from remote sensing observation. These data will be whether or how combined effectively to produce better land cover map that is...
