[postgis-users] Projection question

[Ehud Shabtai]

Hi,

I got some linestring data in postgis, which is stored using lat/lon
coordinates.
I need to use postgis to buffer some lines and I'd like to specify the
buffer size in meters.
I currently use something like this: 'select
transform(buffer(transform(the_geom, 32636), 100), 4326);'

As I have data from all around the world, is there a single projection
which would preserve the distance for every location?

Thanks,

Ehud.
