With its powerful features and intuitive interface, developers can efficiently manage and manipulate geospatial information within their .NET applications.

Prerequisites

Before diving into the intricacies of Aspose.GIS for .NET, ensure you have the following prerequisites set up:

1. Download and Installation

Visit the download link to acquire the latest version of Aspose.GIS for .NET. Follow the installation instructions provided to integrate it seamlessly into your development environment.

2. Namespace Import

To begin utilizing Aspose.GIS for .NET, import the necessary namespaces into your project. This step allows you to access the functionalities provided by the library effortlessly.

using Aspose.Gis;
using Aspose.Gis.Formats.GeoJson;
using Aspose.Gis.Geometries;
using Aspose.GIS.Examples.CSharp;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

Let’s explore a practical example to demonstrate how to limit precision when writing geometries using Aspose.GIS for .NET:

Step 1: Define Precision Options

First, create an instance of GeoJsonOptions to specify precision settings for writing geometries.

var options = new GeoJsonOptions
{
    // Limit X and Y coordinates to 3 fractional digits.
    XYPrecisionModel = PrecisionModel.Rounding(3),

    // Write all fractional digits of the Z coordinate.
    ZPrecisionModel = PrecisionModel.Exact
};

Step 2: Set Output Path

Designate the output path where the processed data will be saved.

var path = "Your Document Directory" + "LimitPrecisionWhenWritingGeometries_out.json";

Step 3: Create and Populate Geometry

Instantiate a VectorLayer and construct the desired geometry, such as a point, with specified coordinates.

using (VectorLayer layer = VectorLayer.Create(path, Drivers.GeoJson, options))
{
    var point = new Point();
    point.X = 1.8888888;
    point.Y = 1.00123;
    point.Z = 1.123456789;

    Feature feature = layer.ConstructFeature();
    feature.Geometry = point;
    layer.Add(feature);
}

Step 4: Read and Verify Precision

Open the saved file and retrieve the geometry to ensure the desired precision settings are applied correctly.

using (VectorLayer layer = VectorLayer.Open(path, Drivers.GeoJson))
{
    var point = (IPoint)layer[0].Geometry;

    // Output: 1.889, 1.001, 1.123456789
    Console.WriteLine("{0}, {1}, {2}", point.X, point.Y, point.Z);
}

Conclusion

By following this step-by-step guide, you can effectively limit precision when writing geometries using Aspose.GIS for .NET. This feature enhances data management and ensures consistency in spatial information representation within your applications.
