我得到了这个例外,并且不知道我做错了什么。 我用线性环创建了两个多边形。 然后我试着找到交叉与否。 我得到了这个例外:
com.vividsolutions.jts.geom.TopologyException:side location conflict [(-1.7542192568359292E-100,1.7542192568359284E-100,0.0)]
这是stackTrace:
com.vividsolutions.jts.geom.TopologyException: side location conflict [ (-1.7542192568359292E-100, 1.7542192568359284E-100, 0.0) ]

EdgeEndStar类中发生异常:
//Debug.print(rightLoc != currLoc, this);
if (rightLoc != currLoc)
throw new TopologyException("side location conflict", e.getCoordinate());
if (leftLoc == Location.NONE) {
Assert.shouldNeverReachHere("found single null side (at " + e.getCoordinate() + ")");
}
currLoc = leftLoc;
边缘有问题有坐标:
//coordinate: (-262.9001323617947, 313.3121772356619, 0.0)
//coordinate: (-232.77552855071107, 332.43790711803985, 0.0)
请告诉我我的错误。 我在google上看过几个同样例外的帖子。有时我会得到这个例外,有时候不会。取决于人物的形状:)
我在:linearRing和Polygon上都调用了isValid()。两个对象都有效。
System.out.println("=== === ===");
LinearRing linearRing = geometryFactory.createLinearRing(coordinates.toArray(new Coordinate[coordinates.size()]));
IsValidOp isValidOp = new IsValidOp(linearRing);
System.out.println("LinearRing: closed?" + linearRing.isClosed() + " valid?" + linearRing.isValid() + " isValidOp.isValid(); " + isValidOp.isValid());
Polygon polygon =geometryFactory.createPolygon(linearRing, null);
isValidOp = new IsValidOp(polygon);
System.out.println("Polygon valid? " + polygon.isValid() +" isValidOp" + isValidOp.isValid());
return new BaseGeometry(polygon);
我不知道我做错了什么。
答案 0 :(得分:3)
然后验证操作返回false。 描述说某些位置的点太靠近了,geotools认为线性环本身相交。 我已经将coodinates截断为5位数后点,它有所帮助。精度太高了。
问题解决了。
