This mapplet will generate from an area of interest (AOI) polygon, a tile indexes layout that nicely fit over the AOI polygon. Note: only AOI polygons with projected coordinates are supported.

The tile width, and tile height are parameters that can be changed. Each tile will be given a name derived from the bottom left corner of the tile, truncated by a number of digits parameter. For example, if the bottom left coordinate is (123456, 12345678) and the number of digits to truncate parameter is 3, then the resultant tile name would be 123_12345.
