[postgis-users] Is PostGIS for me?

[Milo van der Linden]

If you want to do distances like that, without any data it's of no use.

You might consider looking at openstreetmap's functions to import data 
into postgis, this will at least give you some point information 
depending on how well your area of interest is mapped.

But in general, the answer is YES WE CAN. postgis is excelent at 
calculating distances (as the crow flies) between points.
