[postgis-devel] Bit setting to compress PostGIS geometries

[Daniel Baston]

Hi,

I've been experimenting with a cool technique to reduce the size of PostGIS
geometries by setting insignificant bits to zero, which makes the geometry
objects more compressible.

I described the technique in a post here, which shows some test results:

I'm on the fence about whether something like this has a place in the
PostGIS core, but am leaning towards "yes." What do others think?

Dan
