Check Geometry Contains Another

Introduction

Aspose.GIS for .NET is a powerful library that enables developers to work with geospatial data seamlessly within their .NET applications. Whether you’re building a mapping application, performing geospatial analysis, or integrating location-based features into your software, Aspose.GIS simplifies the process by providing intuitive APIs and robust functionality.

Prerequisites

Before diving into using Aspose.GIS for .NET, ensure you have the following prerequisites:

1. .NET Development Environment Setup

Ensure you have a working .NET development environment set up on your machine. This includes having the .NET SDK installed and configured properly.

2. Aspose.GIS Installation

Install Aspose.GIS for .NET by downloading the library from the release page here. Follow the installation instructions provided in the documentation here to integrate Aspose.GIS into your project.

3. Basic Understanding of C#

Familiarize yourself with the C# programming language as Aspose.GIS for .NET is primarily used with C#.

Import Namespaces

In your C# project, import the necessary namespaces to utilize Aspose.GIS functionalities:

using Aspose.Gis.Geometries;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

Step 1: Define Geometry Objects

First, define the geometry objects using Aspose.GIS classes:

var geometry1 = new Polygon();
geometry1.ExteriorRing = new LinearRing(new[]
{
    new Point(0, 0),
    new Point(0, 4),
    new Point(4, 4),
    new Point(4, 0),
    new Point(0, 0),
});
geometry1.AddInteriorRing(new LinearRing(new[]
{
    new Point(1, 1),
    new Point(1, 3),
    new Point(3, 3),
    new Point(3, 1),
    new Point(1, 1),
}));
var geometry2 = new Point(2, 2);

Step 2: Check Spatial Containment

Next, check if one geometry contains another:

Console.WriteLine(geometry1.SpatiallyContains(geometry2)); // False

Step 3: Define Another Geometry

Define another geometry object:

var geometry3 = new Point(0.5, 0.5);

Step 4: Check Spatial Containment Again

Check if the newly defined geometry is contained within the first geometry:

Console.WriteLine(geometry1.SpatiallyContains(geometry3)); // True

Step 5: Equivalent Functionality

Understand that a.SpatiallyContains(b) is equivalent to b.Within(a):

Console.WriteLine(geometry3.Within(geometry1)); // True

Conclusion

In conclusion, Aspose.GIS for .NET provides powerful tools for handling geospatial data in .NET applications. By following this guide and utilizing the provided example, you can efficiently perform spatial containment checks and leverage other geospatial functionalities within your projects.
