Investigation of Impervious surface and Urban Surface Temperature in Qaemshahr
Information on a variation of impervious surface is useful for understanding urbanization and its impacts on the hydrological cycle, water management, surface energy balances, urban heat island, and biodiversity. This research attempts to detect impervious surfaces and its changes by satellite imagery in Qaemshahr. The relationship between impervious surfaces and changes in land surface tempera...
متن کاملSurface Urban Heat Island in Shanghai, China: Examining the Relationship between Land Surface Temperature and Impervious Surface Fractions Derived from Landsat Etm+ Imagery
This paper investigates the relationship between the surface urban heat islands (SUHI) and the percent impervious surface area (%ISA) in Shanghai, China. The %ISA was characterized from a Landsat-7 ETM+ multispectral dataset using the Linear Mixture Spectral Analysis (LMSA). Several critical steps being taken to derive %ISA were discussed, including atmospheric and geometric correction, water f...
متن کاملLandsat Etm Sub-pixel Analysis of Urban Landscape Using Fuzzy C- Means Clustering and Differentiated Impervious Surface Classes
Fuzzy c-means clustering (FCM) algorithm has been used to analyze the sub-pixel composition of medium spatialresolution satellite image (i.e., Landsat ETM). As urban landscape shows complex patterns of land cover composition and setting, it is difficult to have high accuracy in estimating urban land cover composition from Landsat image because of the mixed pixel problem. This study evaluates th...
متن کاملUse of impervious surface in urban land-use classification
Impervious surface has been recognized as a key indicator in assessing urban environments. However, accurate impervious surface extraction is still a challenge. Effectiveness of impervious surface in urban land-use classification has not been well addressed. This paper explored extraction of impervious surface information from Landsat Enhanced Thematic Mapper data based on the integration of fr...
متن کاملEstimation of species diversity of trees and shrubs using ETM+ sensor data (Case study of forests in Qalajeh Kermanshah province)
The use of remote sensing techniques as a suitable solution to estimate the levels of species diversity is of high importance for the sustainable management of forests. In order to investigate the potential of using sensor data from Landsat 7 ETM+ to estimate species diversity in the Zagros forests, digital data related to the August 7, 2002 from forests in the Qalajeh Kermanshah Province were ...
