Spectral Correlation Mapper (SCM): An Improvement on the Spectral Angle Mapper (SAM)
The classification methods for feature spectra are based on a comparison of the spectral image with a reference spectrum (endmembers or spectral libraries). The comparison is accomplished through a criterion of similarity. The Spectral Angle Mapper SAM is one of the leading classification methods because it evaluates the spectra similarity in order to repress the influence of the shading to acc...
متن کاملJeffries Matusita-spectral Angle Mapper (jm-sam) Spectral Matching for Species Level Mapping at Bhitarkanika, Muthupet and Pichavaram Mangroves
This paper proposes a novel hyperspectral matching algorithm by integrating the stochastic Jeffries-Matusita measure (JM) and the deterministic Spectral Angle Mapper (SAM), to accurately map the species and the associated landcover types of the mangroves of east coast of India using hyperspectral satellite images. The JM-SAM algorithm signifies the combination of a qualitative distance measure ...
متن کاملSubpixel Impervious Surface Mapping
Identified by the EPA as the leading threat to surface water quality in the United States, nonpoint source (NPS) pollution is channeled into rivers and streams via impervious surfaces. Impervious surfaces are anthropogenic features, such as roads, buildings, and parking lots, through which water cannot infiltrate into the soil. Research from the past 15 years shows a consistent, inverse relatio...
متن کاملmetrics for the detection of changed buildings in 3d old vector maps using als data (case study: isfahan city)
هدف از این تحقیق، ارزیابی و بهبود متریک های موجود جهت تایید صحت نقشه های قدیمی سه بعدی برداری با استفاده از ابر نقطه حاصل از لیزر اسکن جدید شهر اصفهان می باشد . بنابراین ابر نقطه حاصل از لیزر اسکنر با چگالی حدودا سه نقطه در هر متر مربع جهت شناسایی عوارض تغییر کرده در نقشه های قدیمی سه بعدی استفاده شده است. تمرکز ما در این تحقیق بر روی ساختمان به عنوان یکی از اصلی ترین عارضه های شهری می باشد. من...
Mapping Impervious Surface Distribution with Integration of SNNP VIIRS-DNB and MODIS NDVI Data
Data from the U.S. Defense Meteorological Satellite Program’s Operational Line-scan System are often used to map impervious surface area (ISA) distribution at regional and global scales, but its coarse spatial resolution and data saturation produce high inaccuracy in ISA estimation. Suomi National Polar-orbiting Partnership (SNPP) Visible Infrared Imaging Radiometer Suite’s Day/Night Band (VIIR...
