获取多个多边形的总边界框(使用C# NetCore NetTopologySuite)

using NetTopologySuite.Geometries;
using NetTopologySuite.Operation.Overlay;

Polygon polygon1 = new Polygon(new LinearRing(new Coordinate[] {
    new Coordinate(0, 0),
    new Coordinate(0, 1),
    new Coordinate(1, 1),
    new Coordinate(1, 0),
    new Coordinate(0, 0)
}));

Polygon polygon2 = new Polygon(new LinearRing(new Coordinate[] {
    new Coordinate(1, 1),
    new Coordinate(1, 2),
    new Coordinate(2, 2),
    new Coordinate(2, 1),
    new Coordinate(1, 1)
}));

// 创建多边形集合
GeometryCollection geometryCollection = new GeometryCollection(new Geometry[] { polygon1, polygon2 });

Envelope envelope = geometryCollection.Envelope;

double minX = envelope.MinX;
double minY = envelope.MinY;
double maxX = envelope.MaxX;
double maxY = envelope.MaxY;
