In this tutorial, we’ll learn how to replace polygons with lines using Aspose.GIS for .NET. This process can be useful in various GIS applications where converting complex polygon geometries into simpler line geometries is required for further analysis or visualization.

Step 1: Define Source Geometry

First, define the source geometry containing polygons that you want to replace with lines.

var srcGeometry = Geometry.FromText(@"GeometryCollection (POLYGON((1 2, 1 4, 3 4, 3 2)), Point (5 1))");

Step 2: Replace Polygons with Lines

Next, use the ReplacePolygonsByLines() method to convert polygons into lines.

var dstGeometry = srcGeometry.ReplacePolygonsByLines();

Step 3: Display Results

Finally, display the original and converted geometries to see the transformation.

Console.WriteLine($"source: {srcGeometry.AsText()}");
Console.WriteLine($"result: {dstGeometry.AsText()}");

Conclusion

Aspose.GIS for .NET offers powerful functionalities for manipulating spatial data, including the ability to replace polygons with lines. By following this tutorial, you’ve learned how to perform this transformation seamlessly in your .NET applications.
