Hyperspectral discrimination of tree species with different classifications using single- and multiple-endmember
Azadeh Ghiyamat,Helmi Zulhaidi Mohd Shafri,Ghafour Amouzad Mahdiraji,Abdul Rashid Mohamed Shariff,Shattri Mansor +4 more
TL;DR: High potential of multiple-endmember is shown to be employed in remote sensing applications in the future for improving tree species discrimination accuracy and when discrimination become more challenging, the performance difference between different SMTs is increased.

Mapping the dynamics of eastern redcedar encroachment into grasslands during 1984–2010 through PALSAR and time series Landsat images
Jie Wang,Xiangming Xiao,Xiangming Xiao,Yuanwei Qin,Jinwei Dong,George L. Geissler,Geli Zhang,Nicholas I. Cejda,Brian Alikhani,Russell Doughty +9 more
TL;DR: In this paper, a pixel and phenology-based mapping algorithm was developed to analyze PALSAR mosaic data in 2010 and all the available Landsat 5/7 data during 1984-2010 with the Google Earth Engine (GEE) platform.

Forest tree species discrimination in western Himalaya using EO-1 Hyperion
TL;DR: The potential utility of narrow spectral bands of Hyperion data in discriminating tree species in a hilly terrain is demonstrated and classification accuracy achieved with Hyperion bands was significantly higher than Landsat TM bands.

Use of imaging spectroscopy to discriminate symptoms caused by Heterodera schachtii and Rhizoctonia solani on sugar beet
TL;DR: The development of symptoms caused by the plant parasitic nematode Heterodera schachtii and the fungal pathogen Rhizoctonia solani anastomosis group 2-2IIIB alone or in combination was studied by leaf reflectance recorded with a hyperspectral imaging system.

Mapping of land degradation from space: a comparative study of Landsat ETM+ and ASTER data
Jay Gao,Yansui Liu +1 more
TL;DR: In this article, the role of spectral and spatial resolutions in mapping land degradation from space-borne imagery using Landsat ETM+ and ASTER data as examples was compared, and the spectral resolution was not as important as the information content of individual bands in accurately mapping land covers automatically.

Pattern classification and scene analysis
Richard O. Duda,Peter E. Hart +1 more
TL;DR: In this article, a unified, comprehensive and up-to-date treatment of both statistical and descriptive methods for pattern recognition is provided, including Bayesian decision theory, supervised and unsupervised learning, nonparametric techniques, discriminant analysis, clustering, preprosessing of pictorial data, spatial filtering, shape description techniques, perspective transformations, projective invariants, linguistic procedures, and artificial intelligence techniques for scene analysis.

A new method for non-parametric multivariate analysis of variance
TL;DR: In this article, a non-parametric method for multivariate analysis of variance, based on sums of squared distances, is proposed. But it is not suitable for most ecological multivariate data sets.

TL;DR: Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.
