''' Shapeless handling of WKB geometries.

Use approximate_wkb() to copy an approximate well-known binary representation of
a geometry. Along the way, reduce precision of double floating point coordinates
by replacing their three least-significant bytes with nulls. The resulting WKB
will match the original at up to 26 bits of precision, close enough for
spherical mercator zoom 18 street scale geography.

Reduced-precision WKB geometries will compress as much as 50% smaller with zlib.

WebGL rendering of live OpenStreetMap data using the OSM-Solar color scheme.

Built with Squares, rendered with false colors to show line structure.

Words about this on my blog.
