GLOBAL LROC NAC STEREO OBSERVATIONS

Shapefile of images targeted by the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Cameras (NAC) for geometric stereo. Images were targeted to provide appropriate lighting conditions and imaging geometry for extracting terrain. Images with large amounts of jitter have been removed from this dataset. For more information on the imaging criteria used for acquiring stereo images, refer to: Henriksen, M. R., Manheim, M. R., Burns, K. N., Seymour, P., Speyerer, E. J., Deran, A., Boyd, A. K., Howington-Kraus, E., Rosiek, M. R., Archinal, B. A., and Robinson, M. S. (2017). Extracting accurate and precise topography from LROC narrow angle camera stereo observations. Icarus, 283, 122-137. http://doi.org/10.1016/j.icarus.2016.05.012

Polygon shapefiles are available in the IAU Moon 2000 Geographic Coordinate System in both the -180 to 180 and 0 to 360 longitude domains.
