Are there plans to fix the link to the API docs on vividsolutions.com for JTS? Not sure if it is known that the link doesn't work or not. Thanks Laine...
Are there any working examples out there? I'm learning how to use JTS and I think there must be better ways to implement some functions I'm working on. Thanks...
I am new to JTS and have been working through the concepts via the example provided and several that I have developed on my own. However, I am not 100% sure...
The following snippet was working ok with jts 1.2: public static void cornerPoligon() throws ParseException { String wktA = "POLYGON((10 10, 10 20, 20 20, 20...
In JTS 1.2 and 1.3, i noticed a discrepancy between the comments of the Coordinate.equals(Object o) method (the routine ignores the z...) and what it really...
Hello I am quite new to JTS so excuse me if this question is stupid or answered elsewhere - I did have a look at the archives. I have populated an array of...

Hi, The result of union operation over 2 connected LineString is a MultiLineString. I suppose this is conform to the SFS (?), but how can i get a single ...
To all JTS users: We have changed the official name of the JTS API to the "JTS Topology Suite". This avoids potential trademark infringement issues with Sun...
Hi, I have a simple question here. According to JTS spec, JTS conforms to the Simple Features Specification for SQL. From the spec of JTS, spatial data I/O in...
[I'm cross-posting this to the JTS list, since it might be of general interest] Andrea, You're correct in noting that for repeated evaluation of an overlay...
Yep, that's the general idea. I guess the tricky part is specifying the dissolve (or union) operation in a flexible way. As Andrea pointed out, what he really...
In this case with these two polygons: POLYGON ((545 317, 617 379, 581 321, 545 317)). POLYGON ((484 290, 558 359, 543 309, 484 290)). when i try an union...

Hi. I'll try to develop one module to union of buffered points. In the case buffered size was too small and buffering of points using this size resulted to...
Try using RobustCGAlgorithms#computeOrientation. Use two points of the splitting line, and a point from one of the polygons. It might be best to use the...
(Bonus - I can answer two questions at once here... ) cdlee, The polygons in your message are classic cases that will cause robustness problems: Large...
