RE: [postgis] JTS(Java Topology Suite) will be available until th e end of this year.

Martin Davis-2
Unfortunately the JTS delivery schedule has slipped a bit, due to some
technical challenges with realizing our ambitious goal of developing robust
code supporting an explicit precision model.  

We're hoping to have JTS 1.0 released by the end of December - check the Web
site around that time for details.

As for porting JTS to Java 1.1, JTS uses the Collections API pretty
extensively, so it might be a bit of work converting it to Java 1.1.
However, if that was done I don't think there are any fundamental
limitations that would prevent it from working in 1.1.

Hello.

  JTS(Java Topology Suite), one of the greatest opensource GIS project, is
still not available. This project's team will finish by the end of this
year? And JTS is based on Java2, can it to ported to JDK 1.1.x ?  JTS seemed
to use graphics, so converting to JDK 1.1.x will be easy.

Is there any chance of an early release, even if it is just the base
types?
I'd really like to start using the base types (Point, Envelope, ...) as
building blocks for the work I'm doing.
I'm currently adding Web Map Server and Web Feature Server support to
http://geotools.sf.net as part of the http://mapbuilder.sf.net project.

That's not going to be a problem, GeoTools now automatically builds as two
versions, one for Java2 and one which uses suns Collections for Java1.1
extension.

I can probably apply the same automated translation to JTS once it's out so
that it can run under 1.1.

If you use ANT to manage your build process then I can send you a copy of
the relevant parts of out build scripts.  The tricky bit is usually the use
of a small number of function which were added to random bits of Java2, and
these will have to be worked round by hand.  I'm more than happy to do this
though.

I'm looking forward to the arrival of JTS, I'm hopeful that it can form a
common basis across a number of projects.

James

p.s. Appologies for carrying out what is essentially a JTS only discussion
on the postgis mailing list, but this seems to be the only appropriate
forum at the moment.
