Hello,
I've been trying to read and generate a graph from a shape file, with some
troubles though because linestrings intersections are not recognized so i
had to manually process the data. The way i am doing it now is a bit
complicated and it takes more than one minute to provide results because
its a union of 2 geometries with plenty elements..
Do you happen to know a faster method that could help me ?
Here is a part of the code that unifies the geometries of the lines and
points based on which i am creating
List<LineString> lines = polys2lines(networkFC);
GeometryFactory geomFactory = new GeometryFactory();
Geometry grandMls = geomFactory.buildGeometry(lines);
Point mlsPt = geomFactory.createPoint(grandMls.getCoordinate());
Geometry nodedLines = grandMls.union(mlsPt);
lines.clear();
for (int k = 0, n = nodedLines.getNumGeometries(); k < n; k++) {
Geometry g = nodedLines.getGeometryN(k);
if (g instanceof LineString) {
lines.add((LineString)g);
}
}
