[Jts-topo-suite-user] Merging detached polygons into a single polygon

[Brian S. R. <ji...@gm...>]

Hi Dr Martin,

I have two polygon geometries having following coordinates:

Polygon 1: [(0,0) (10,0) (10,10) (0,10) (0,0)]

Polygon2: [(15,0) (19,0) (19,10) (15,10) (15,0)]

These two are rectangles aligned each other but detached.

I need to merge these two to come out with a single polygon. I used
Geometrycollection and union method.
However, result is a multipolygon of these two (see below).

Result:
Aggregated Geometry: MULTIPOLYGON (((0 0, 10 0, 10 10, 0 10, 0 0)), ((15 0,
19 0, 19 10, 15 10, 15 0))).

Any idea?

Best Brian.
