Correlating Apollo Soil Mineralogical Data With Kaguya Spectral Data for a Global Mineralogical Classification

Hyperspectral Image Classification for Mineralogical Identification

Classification is broadly used in a range of exploration technologies. This paper will summarize standard classification methods and provide a new hybrid method for classifying spectra used in mapping mineralogy with hyperspectral remote sensing data. Classification methods commonly employed do not allow the user specifically to identify key features that give confidence as to the quality of th...

Tile crystal structures of sjogrenite and pyroaurite, two stacking modifications of approximate composition Mg.Fe.(OH),.(CO.).4H.O, have been determined by X-ray diffraction using three-dimensional methods. Sjogrenite is hexagonal, with a 3,13, C 15.66 A, space group P6.!mmc, Z = !; pyroaurite is rhombohedral, with aH 3,13, CH 23.49 A, space group R3m or R3m, Z = i. Both structures are based on...

"ENVI Processing of AVIRIS Hyperspectral Data for Mineralogical Classification of El Pico de Orizaba Volcano, Mexico

Global mineralogical and aqueous mars history derived from OMEGA/Mars Express data.

Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new information on Mars' geological and climatic history. Phyllosilicates formed by aqueous alteration very early in the planet's history (the "phyllocian" era) are found in the oldest terrains; sulfates ...

Optimum Ensemble Classification for Fully Polarimetric SAR Data Using Global-Local Classification Approach

In this paper, a proposed ensemble classification for fully polarimetric synthetic aperture radar (PolSAR) data using a global-local classification approach is presented. In the first step, to perform the global classification, the training feature space is divided into a specified number of clusters. In the next step to carry out the local classification over each of these clusters, which cont...
