Lunar Reconnaissance Orbiter Camera

Controlled 1 m/pixel North Pole Controlled Max Pixel Mosaic

This is a maximum-pixel mosaic made using a set of 9687 controlled images. This is a subset of the images in a controlled mosaic consisting of 9687 NAC images of the lunar north polar region acquired between 2009 and 2014. Control solutions were performed using the ISIS jigsaw application using 405,532 points and over three million measures. The network was constrained using 16,302 points in 226 images that were tied to Lunar Orbiter Laser Altimeter (LOLA) track data. The residuals from the bundle adjustment performed by ISIS jigsaw were (in pixels) a solution variance of 0.40, a mean of 0.52, a standard deviation of 0.48, and a maximum of 13.0. The mosaic was created by finding the maximum pixel value at each pixel location in a stack of images. The images were map-projected using a 20 meter pixel scale polar digital elevation model derived from LOLA tracks.

The mosaic range is 84 to 90 degrees and is stored as 40 polar stereographic map tiles. The mosaic is tiled into with a scheme that includes four latitudinal bands of 1.5 degrees radiating from the pole. There are four tiles in the first band (88.5 to 90 degrees latitude), eight in the second (87 to 88.5 degrees latitude), twelve in the third (85.5 to 87 degrees latitude), and sixteen in the fourth band (84 to 85.5 degrees latitude).

Each file is named with the following pattern:

NAC_POLE_NORTH_CM_MAX_P###N????

where:

  • P indicates the map projection (P=Polar Stereographic)
  • ###N indicates the center latitude in 1/10th degrees North (N)
  • ???? indicates the center longitude in 1/10th degrees East
