Point Geometry

Point 생성

API를 사용하여 지리 공간 점을 만드는 것은 다음과 같은 코드 샘플에서 볼 수 있듯이 간단하고 쉽습니다.

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
Point point = new Point(40.7128, -74.006);

MultiPoint 생성

Aspose.GIS for .NET은 점 컬렉션을 단일 MultiPoint 클래스로 표현할 수 있는 기능을 제공합니다. 각 Point의 위도-경도 정보로 정의된 하나 이상의 Point를 포함할 수 있습니다.

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
MultiPoint multipoint = new MultiPoint();
multipoint.Add(new Point(1, 2));
multipoint.Add(new Point(3, 4));

Line String Geometry

Point Geometries을 지정하여 Line String을 만들 수 있습니다.

Line String 생성

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
LineString line = new LineString();

line.AddPoint(78.65, -32.65);

line.AddPoint(-98.65, 12.65);

MultiLine String 생성

MultiLine string은 Point geometries로 구성된 Line Strings의 컬렉션입니다. 

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
LineString firstLine = new LineString();
firstLine.AddPoint(7.5, -3.5);
firstLine.AddPoint(-9.6, 12.6);

LineString secondLine = new LineString();
secondLine.AddPoint(8.5, -2.6);
secondLine.AddPoint(-8.6, 1.5);

MultiLineString multiLineString = new MultiLineString();
multiLineString.Add(firstLine);
multiLineString.Add(secondLine);

Polygon Geometry

Polygon은 LinearRing 형식의 Point로 정의된 Point geometries 컬렉션입니다.

Polygon 생성

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
Polygon polygon = new Polygon();

LinearRing ring = new LinearRing();
ring.AddPoint(50.02, 36.22);
ring.AddPoint(49.99, 36.26);
ring.AddPoint(49.97, 36.23);
ring.AddPoint(49.98, 36.17);
ring.AddPoint(50.02, 36.22);

polygon.ExteriorRing = ring;

MultiPolygon 생성

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
LinearRing firstRing = new LinearRing();
firstRing.AddPoint(8.5, -2.5);
firstRing.AddPoint(-8.5, 2.5);
firstRing.AddPoint(8.5, -2.5);
Polygon firstPolygon = new Polygon(firstRing);

LinearRing secondRing = new LinearRing();
secondRing.AddPoint(7.6, -3.6);
secondRing.AddPoint(-9.6, 1.5);
secondRing.AddPoint(7.6, -3.6);
Polygon secondPolygon = new Polygon(secondRing);

MultiPolygon multiPolygon = new MultiPolygon();
multiPolygon.Add(firstPolygon);
multiPolygon.Add(secondPolygon);

Hole이 있는 Polygon 생성

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
Polygon polygon = new Polygon();

LinearRing ring = new LinearRing();
ring.AddPoint(50.02, 36.22);
ring.AddPoint(49.99, 36.26);
ring.AddPoint(49.97, 36.23);
ring.AddPoint(49.98, 36.17);
ring.AddPoint(50.02, 36.22);

LinearRing hole = new LinearRing();
hole.AddPoint(50.00, 36.22);
hole.AddPoint(49.99, 36.20);
hole.AddPoint(49.98, 36.23);
hole.AddPoint(50.00, 36.24);
hole.AddPoint(50.00, 36.22);

polygon.ExteriorRing = ring;
polygon.AddInteriorRing(hole);

Geometry Collection 생성

// For complete examples and data files, please go to https://github.com/aspose-gis/Aspose.GIS-for-.NET
Point point = new Point(40.7128, -74.006);

LineString line = new LineString();
line.AddPoint(78.65, -32.65);
line.AddPoint(-98.65, 12.65);

GeometryCollection geometryCollection = new GeometryCollection();
geometryCollection.Add(point);
geometryCollection.Add(line);
