Mercury MESSENGER MDIS Basemap MD3 Color Global Mosaic 665m (64ppd)
This mosaic shows Mercury's colors as viewed by placing images from MESSENGER's 1000 nm, 750 nm, and 430 nm narrow-band filters in the red, green, and blue channel respectively. This is not what Mercury would look like to the human eye, but rather by using a wider range of wavelengths, color differences on Mercury's surface can be accentuated beyond those visible to a person. The projection defined is Simple Cylindrical centered on 0° latitude and 0° longitude.
The 3-color Map Projected Multispectral RDR (MD3) data set consists of a mosaicked global color map of 3-color image sets, as reflectance corrected to i = 30º, e = 0º, and g = 30º sampled at a scale of 128 pixels per degree, compiled from images taken as a part of the regional 3-color map campaign. This is version 1 of the map, delivered at end of mission. Instead of the value from any single image being used at a particular pixel location in a given wavelength band, the value used is the average from all of the images at that location where criteria for image scale, photometric geometry, and detector temperature are met.
This mosaic contains data acquired by the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) Mercury Dual Imaging System (MDIS) instrument.
