Green areas cool the climate of a city, reduce the energy consumption caused by the urban heat island (UHI) effect, and bring along carbon savings. However, the calculation of carbon savings due to the cooling effect of green areas is still not well understood. We have used a Landsat Enhanced Thematic Mapper Plus (ETM+) image of Beijing, to identify the cooled areas, compute the possible energy...

Landsat 7 Enhanced Thematic Mapper Plus satellite images presents an important data source for many applications related to remote sensing. An effective image restoration method is proposed fill the missing information in images. The segmentation of find SLIC Super pixels and then Segments. Boundary Reconstruction performed using Edge Matching area region. Peak Signal Noise Ratio Root Mean Squa...

this study determined some spectral characteristics and relationship between landsat spectral reflectance and soil surface color in the arid region of iran (kashan). the study carried out in the kashan area that covers 90000 ha. consisting of mountain, hills and flood plain. enhanced thematic mapper (etm+) data collected on july 2002 were used for this research. the color composite images produ...

The Advanced Land Imager (ALI) is a multispectral sensor onboard the National Aeronautics and Space Administration Earth Observing 1 (EO-1) satellite. It has similar spatial resolution to Landsat-7 Enhanced Thematic Mapper Plus (ETM+), with three additional spectral bands. We developed new algorithms for estimating both land surface broadband albedo and leaf area index (LAI) from ALI data. A re...

Multi-instrument data sets present an interesting challenge to feature extraction algorithm developers. Beyond the immediate problems of spatial co-registration, the remote sensing scientist must explore a complex algorithm space in which both spatial and spectral signatures may be required to identify a feature of interest. We describe a genetic programming/supervised classifier software syste...

Land Surface Temperature monitoring major parameters of climate change country studies. In this paper, two methods to retrieve the land surface temperature (LST) from thermal infrared data supplied by band 6 of the Enhanced Thematic Mapper Plus (ETM+) sensor onboard the Landsat 7 satellite are compared. The two are the mono-window algorithm developed by Qin et al. [International Journal of Remo...

The requirements for planimetric accuracy of satellite image correction are discussed in the context of base mapping accuracy standards. Measurements are presented for SPOT and the Landsat Thematic Mapper. Two-dimensional accuracies as low as 7.2 m (TM) and 6.4 m (SPOT) were measured, these being close to the level of noise in the measurement techniques. NATO class A 1:50000 scale standards wer...

Many land-management agencies are caught between decreased budgets and increasing public interest. Furthermore, semi-arid landscapes are sensitive to management prescriptions and use, and require a significant amount of monitoring in order to assess vegetation productivity and health. The purpose of this study was to evaluate the use of Landsat Enhanced Thematic Mapper (ETM) Imagery to monitor ...
