You could use a different encoding algorithm than the one used by
Google.
The file:
polylibs.googlepages.com/CO06.SET
contains individual poly definitions for every county in California.
It is difficult to decode unless you know what translation table was
used.
It has another advantage of approximately four times the compression
over using Google's poly encoding algorithm. Zoom level strings are
eliminated. Common boundaries between counties are represented once.
Run length encoding reduces the number of bits required.
The other states are contained in similarly names files - "CO??.SET"
where "??" is the two digit state id assigned by the Census
Department. The files can be loaded with JSON.
For an example, look at:
