Detecting Urban Land-Use and Land-Cover Changes in Mississauga Using Landsat TM Images
The City of Mississauga in Ontario has been experiencing a fast urban growth in the past two decades which has caused rapid loss of the valuable farm and open space land. Land-use and land-cover maps of the City were produced from Landsat TM images for 1985 and 1999, spanning a period of 14 years. Dramatic changes in land use and land cover have occurred, with loss of forest, cropland and water...
متن کاملUrban Built-Up Area Extraction from Landsat TM/ETM+ Images Using Spectral Information and Multivariate Texture
Urban built-up area information is required by various applications. However, urban built-up area extraction using moderate resolution satellite data, such as Landsat series data, is still a challenging task due to significant intra-urban heterogeneity and spectral confusion with other land cover types. In this paper, a new method that combines spectral information and multivariate texture is p...
متن کاملFractional Vegetation Cover Estimation In Urban Environments
Quality of life in urban environments is closely related to vegetation cover. The Urban growth and its related environmental problems, planners are forced to implement policies to improve the quality of urban environment. Thus, vegetation mapping for planning and managing urban is critical. Given the spectral complexity of the urban environment and the sparse vegetation in these areas, to gener...

متن کاملCrop area estimation by data-driven decomposition of mixed pixels in Landsat-TM images
Pixel-based classiication is a standard approach towards crop area estimation, but it is unsuited to handle mixed pixels. Therefore, we developed the data-driven decomposition method, which combines the linear mixture model with knowledge of the application domain. A quantitative comparison proved that both concepts lead to more accurate estimates when processing simulated images. Experiments o...
