Scientific OSMcodes grid use the Census (plus national statistics and Weather Forecast) as the main reference-application. The second most important application is to represent parcels, to solve Land Ownership. There are many approaches to the interior-Quadtree:

Summary:

  • single hexadecimal grid (single level) solves by the "maximal enclosed equal-sized squares" approache;

  • multi hexadecimal grid (many hexadecimal levels) solves by the "maximal enclosed various-sized squares" approache;

  • multi base16h grid (free levels) solves by the "maximal enclosed various-sized rectangles" approache, but restricted to the rectangle-orientation of the grid.

So we can use all the power of the base16h grid to implement a "maximal enclosed rectangles of parcels", that is not perfect but it is satisfactory.
