RE: [GENERAL] GIS-type databases using PostgreSQL - Mailing list pgsql-jdbc

The standard is a little bit more than a new PG type. It includes tables
containing metadata features, datums,...

As for the new type, it is displayed in ASCII so all usual programs should
handle it...

There's plenty of existing libraries out there, and the jdbc driver already
has
support for the existing standard types in PostgreSQL (point, line etc).

A few years ago I did write a simple mapping library that handled things
like
co-ordinate transforms and display. I was thinking of updating it to Java2
after PostgreSQL 7.1 was out (as I'm doing with a lot of my stuff).
