Geometri Titik

Buat Titik

Membuat titik geospatial menggunakan API itu sederhana dan mudah seperti yang ditunjukkan dalam contoh kode berikut.

// 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);

Buat MultiTitik

Aspose.GIS untuk .NET menyediakan fasilitas untuk merepresentasikan kumpulan titik sebagai kelas MultiTitik tunggal. Ini dapat berisi satu atau lebih Titik yang didefinisikan oleh informasi lintang-bujur dari setiap Titik.

// 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));

Geometri Garis String

Anda dapat membuat Garis String dengan menentukan Geometri Titik.

Buat Garis String

// 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);

Buat MultiGaris String

Garis String Multi adalah kumpulan Garis String yang dibangun dari geometri Titik.

// 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);

Geometri Poligon

Poligon adalah kumpulan geometri Titik yang didefinisikan oleh Titik dalam bentuk LinearRing.

Buat Poligon

// 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;

Buat MultiPoligon

// 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);

Buat Poligon dengan Lubang

// 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);

Buat Koleksi Geometri

// 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);
