The Lunar Reconnaissance Orbiter Camera (LROC) photometrically normalized 7-color semi-global mosaic using Hapke parameter maps (MDRHAP, w,b,c,bc0,hc,bs0,hs,theta,phi) is in 1 deg x 1 deg tiles for the 7 bands of the WAC. The mosaic was constructed from ~124,300 WAC images acquired from January 21, 2010 to May 1st, 2013. The map was normalized to the angles of phase (g) = incidence (i) = 60°, emission (e) = 0° by Hapke bidirectional reflectance function using Hapke parameter maps. The g, i, and e angles were calculated using the WAC stereo digital terrain model (GLD100). Each pixel value of this mosaic consists of a median of normalized I/F from ~40 months of repeated observations (UV:58-59, visible:136-140 observations in average).

LROC MDRHAP products have the following file names:

WAC_HAPKE_xxxxx_Eaaadoooo.ttt

where:

xxxxx = 5-character band description (3BAND, 321NM, 360NM, 415NM, 566NM, 604NM, 643NM, or 689NM)

E = Equirectangular projection

aaa = latitude center to the tenth of a degree (nn.n) *10

d = direction

N = north

S = south

oooo = longitude center to the tenth of a degree (nnn.n) *10

ttt = data format in IMG or TIF

In ODE, MDRHAP products have the following product IDs:
