Plunder loads its data from static js files.

Those files are generated from the plunder database using the sql files in the geosketch/sql folder.

Originally mountains were broken into three js files by scalerank.

• high scalerank 1,2
• medium scalerank 3,4
• low scalerank 4,5

And rivers were broken into six js files by scalerank, 1 thru 6.

scale = the number of pixels in the radius of the globe, used for realtime map drawing

scalerank = a number from 1 to 6, indicating the relative magnitude of the feature
