Hello.
I've found I couldn't get correct edges and nodes
generated by "Plannar Graph" function with default setting
in OpenJUMP latest
nightbuild(openjump-core-1.2-20081109-bin.zip).
Input Layer(2 Features)
FID:1
LINESTRING (
0 100,
100 100
)
FID:2
LINESTRING (
50 50,
50 150
)
Resulted Output Edge Layer(2Features)
FID:1
LINESTRING (
0 100,
100 100
)
FID:2
LINESTRING (
50 50,
50 150
)
In this result, no cross point/node between two
linestrings generated. Input layer's geometry is same to
output layer's geometry.
However I tried to do for same inout layer using same
function on SIGLE(http://www.projet-sigle.org/)'s OpenJUMP
"the Merge", I could get following "correct" result.
Cross/Insersect point/node available.
Resulted Output Edge Layer(4Features)
FID:1
LINESTRING (
0 100,
50 100
)
FID:2
LINESTRING (
50 50,
50 100
)
FID:3
LINESTRING (
50 100,
100 100
)
FID:4
LINESTRING (
50 100,
50 150
)
Could you improve this situation?
Regards.
