![wac_global_mosaic](wac_global_mosaic.png)


The dataset contains 21541 .png images of the moon surface taken by the lunar orbiter, at periods (1/20/2010 to 1/28/2010, 5/30/2010 to 6/6/2010, 7/24/2010 to 7/31/2010). 
The images are bounded be the following coordinates ([-180.0, -85.0511287798066, 180.0, 85.0511287798066]) i.e coordinates of the left low and right upper corner, 
notice that the dataset does not contain the north and south pole.
The dataset contains 3 zoom levels (5,6,7) at (1024, 4096, 16384) tiles respectively so in total 21541 images are avaliable.
The resolution is 512x512, each image has a metadata which contains the coordinates of the image footprint i.e the coordinates of the corners it also 
contains the square area in km that the image covers. We use the EPSG:4326 coordinate reference system.
