Question

skyline 6.0中iLayer.ExecuteSpatialQuery(iGeometry, IntersectionType.IT_INTERSECT)第一个参数如何设置

Answer 1

iGeometry在skylinev6中就是个Geometry对象。 实现要创建一个对象 在Creator 接口中的GeometryCreator属性能够通过多种方法创建Geometry对象具体可以查阅开发文档。下面有个示例参考一下。

IGeometry cPolygonGeometry = null;
SGWorld sgworld = new SGWorld();
double[] cVerticesArray = new double[] {
-122.415025, 37.76059, 10,
-122.415868, 37.760546, 11,
-122.415922, 37.761244, 12,
-122.415592, 37.761254, 13,
-122.415557, 37.760973, 14,
-122.415081, 37.76099, 15,
};
ILinearRing cRing = sgworld.Creator.GeometryCreator.CreateLinearRingGeometry(cVerticesArray);
cPolygonGeometry = sgworld.Creator.GeometryCreator.CreatePolygonGeometry(cRing, null);
