Unsupervised clustering analysis of spectral data for the Rudaki area on Mercury
2013
We present a study of spectral reflectance data
from Mercury focused on an area that encompasses
the craters Kuiper-Murasaki, Rudaki, and Waters.
The goal is to identify different spectral units and
analyze potential relations among them.
The study region is geologically and spectrally
classified as heavily cratered intermediate terrain (IT)
with mixed patches of high-reflectance red plains
(HRP) and intermediate plains (IP), on the basis of
multispectral images taken by the Mercury Dual
Imaging System (MDIS) [1].
Recent analysis of observations by the Mercury
Atmospheric and Surface Composition Spectrometer
(MASCS) instrument on the MErcury Surface, Space
ENvironment, GEochemistry, and Ranging
(MESSENGER) spacecraft with an unsupervised
hierarchical clustering method shows a comparable
number of units at global scales [2,3]. Analyses on
the local scale reveal a larger number of spectral
units with a substantially more complex relationship
among units.
