[jts-dev] Remove line from within another line
|
JTSers,
Perhaps I am not seeing how I should use JTS to answer my question, so I
thought I would ask.
I have a LinearRing as follows:
LINESTRING (548845.37 3956342.94, 548840.24 3956243.07, 548861.63
3956241.98, 548881.28 3956242.9, 548900.36 3956247.66, 548918.14
3956256.06, 548933.94 3956267.77, 548947.13 3956282.36, 548957.22
3956299.24, 548963.81 3956317.77, 548966.65 3956337.23, 548965.62
3956356.87, 548960.77 3956375.93, 548952.28 3956393.67, 548940.48
3956409.4, 548925.83 3956422.53, 548825.48 3956496.01, 548766.4
3956415.33, 548866.75 3956341.84, 548845.37 3956342.94)
From which I wish to remove the following LineString:
LINESTRING (548845.366 3956342.941, 548866.753 3956341.844, 548766.398
3956415.329)
I have tried using ST_LineDissolver but am not getting the resultant
linestring back.
The solution needs to be robust in that the LinearRing could have
different orientation than the LineString.
Any suggestions?
Regards
Simon
