The Lunar Reconnaissance Orbiter Camera (LROC) Binned Data Record Region of Interest (BDRROI) data product contains a map-projected single-band basemap derived from Narrow Angle Camera (NAC) or Wide Angle Camera (WAC) single-band imaging. The product provides the ability to assess meter and smaller-scale features to facilitate safety analysis of potential landing sites and support science investigations. BDRROIs consist of approximately 50 NAC high-resolution uncontrolled image mosaics at 0.5 m/pixel sampling and four types of WAC mosaics (farside dusk, nearside dawn, north summer, and south summer).

Mosaics of high-priority regions of interest are generated at 0.5 m/pixel and 1 m/pixel scales, depending on viewing and light conditions, and instrument commanding. Polar regions and areas above 60° latitude are mapped to the Polar Stereographic projection. For other latitude regions, the Equirectangular projection is used. To minimize scale and shape distortion for the Equirectangular projection, the reference center latitude is the nearest whole integer of mid-latitude of the mosaic. The image size of each mosaic depends on the chosen areal coverage of the mosaic.

LROC BDRROI products have the following file names:

ccc_ROI_xxxxxxxxxxx_taaadoooo_rrru.IMG

where:

ccc = camera

NAC = narrow angle camera

WAC = wide angle camera

xxxxxxxxxxx = 11-character landing site name

t = projection type

E = equirectangular

O = orthographic

P = polar stereographic

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

d = direction

N = north

S = south

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

rrr = 3-digit resolution

u = resolution units

M = meters/pixel

P = pixels/degree

Note: Not all NAC ROIs have '_rrru'. Not all WAC ROIs have 'taaadooo'.

In ODE, BDRROI products have one of the following product IDs:

CCC_ROI_XXXXXXXXXXX_TAAADOOOO_RRRU

NAC_ROI_XXXXXXXXXXX_EAAADOOOO

WAC_ROI_XXXXXXXXXXX_RRRU
