Abstract
========
The Mercury Dual Imaging System (MDIS) consists of two cameras, a Wide
Angle Camera (WAC) and a Narrow Angle Camera (NAC), mounted on a
common pivot platform. This dataset includes Map Projected Low-
Incidence Angle Basemap RDRs (LOIs) which comprise a global map
of I/F measured by the NAC or WAC filter 7 (both centered near
750 nm) during the Extended Mission at low solar incidence
angles to accentuate albedo and albedo variations, photometrically
normalized to a solar incidence angle (i) = 30 degrees, emission
angle (e) = 0 degrees, and phase angle (g) = 30 degrees, at a spatial
sampling of 256 pixels per degree. The LOI data set is a companion to
the Basemap Data Record (BDR) data set, High Incidence Angle
Illuminated from the East (HIE) data set, and High Incidence
Angle Illuminated from the West (HIW) data set, all of which are
also composed of WAC filter 7 and NAC images, except acquired at
higher solar incidence angles centered at 68 to 78 degrees to
highlight topography.
The map is divided into 54 'tiles', each representing the NW, NE,
SW, or SE quadrant of one of the 13 non-polar or one of the 2 polar
quadrangles or 'Mercury charts' already defined by the USGS. Each tile
also contains 5 backplanes: observation ID; BDR metric, a metric used
to determine the stacking order of component images, modified for the
higher incidence angle centered near 78 degrees; solar incidence
angle; emission angle; and phase angle. |
