Re: [jts-dev] 4th Dimension
That's kind of what we thought.

We will go down the path of writing a custom WKTWriter and Reader. 

Thanks!

The only approach I'm aware of is to implement a custom WKTWriter and Reader which can handle more than 3 dimensions.

It would make a nice addition to the WKTWriter/Reader to support more coordinate dimensions.

Martin,

Hate to bother you again, but we are to the point to persisting a 4 dimension (i.e., X,Y,Z,M) Geometry object to the database. We are currently using the WKTWriter, but it does not support a 4th dimension. Do you have a recommendation on how this has been done?

Many thanks!

Bill

Excellent. 

Thanks for your quick reply.

There's no current plans to add an explicit M dimension to JTS.

You can use additional dimensions (to a limited extent, and with some work) by making use of the CoordinateSequence interface.

Good morning.

Am looking at the JTS Topology Suite project to create a LineString in Java that contains 4 dimensions (Z being elevation and M being timestamp).

Are there plans for this project to support a 4th dimension (M)? Or is there a way to do it that I'm missing?

Many thanks.
