GeoJSON to File GDB Conversion Demystified

Introduction

In the dynamic realm of Geographic Information Systems (GIS), the ability to seamlessly convert data between different formats is crucial. Aspose.GIS for .NET emerges as a powerful ally, offering a comprehensive suite of tools for handling geospatial data effortlessly. In this tutorial, we will delve into the process of converting a GeoJSON layer to a File Geodatabase (File GDB) using Aspose.GIS for .NET.

Prerequisites

Before embarking on this geospatial journey, ensure that you have the following prerequisites in place:

A working knowledge of .NET programming.
Aspose.GIS for .NET installed. If not, download it from here and follow the installation instructions.

Import Namespaces

To kickstart the conversion process, begin by importing the necessary namespaces:

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

Now, let’s break down the process into a step-by-step guide:

Step 1: Set up the GeoJSON Layer

Start by creating a GeoJSON layer with relevant attributes and features. Here’s a snippet to guide you:

string dataDir = "Your Document Directory";
var geoJsonPath = dataDir + "ConvertGeoJsonLayerToLayerInFileGdbDataset_out.json";
using (VectorLayer layer = VectorLayer.Create(geoJsonPath, Drivers.GeoJson))
{
    // Add attributes
    layer.Attributes.Add(new FeatureAttribute("name", AttributeDataType.String));
    layer.Attributes.Add(new FeatureAttribute("age", AttributeDataType.Integer));
    // Construct and add features
    Feature firstFeature = layer.ConstructFeature();
    firstFeature.Geometry = new Point(33.97, -118.25);
    firstFeature.SetValue("name", "John");
    firstFeature.SetValue("age", 23);
    layer.Add(firstFeature);
    Feature secondFeature = layer.ConstructFeature();
    secondFeature.Geometry = new Point(35.81, -96.28);
    secondFeature.SetValue("name", "Mary");
    secondFeature.SetValue("age", 54);
    layer.Add(secondFeature);
}

Step 2: Copy Test Dataset

To preserve the integrity of your test data, create a copy of the dataset. Use the following code snippet:

var sourceFile = "Your Document Directory" + "ThreeLayers.gdb";
var destinationFile = "Your Document Directory" + "ThreeLayersCopy_out.gdb";
RunExamples.CopyDirectory(sourceFile, destinationFile);

Step 3: Convert GeoJSON to File GDB

Now, it’s time to perform the conversion. Utilize the following code:

using (var geoJsonLayer = VectorLayer.Open(geoJsonPath, Drivers.GeoJson))
{
    using (var fileGdbDataset = Dataset.Open(destinationFile, Drivers.FileGdb))
    using (var fileGdbLayer = fileGdbDataset.CreateLayer("new_layer", SpatialReferenceSystem.Wgs84))
    {
        // Copy attributes
        fileGdbLayer.CopyAttributes(geoJsonLayer);
        // Add features
        foreach (var feature in geoJsonLayer)
        {
            fileGdbLayer.Add(feature);
        }
    }
}

Conclusion

In this tutorial, we navigated the intriguing terrain of converting a GeoJSON layer to a File Geodatabase using Aspose.GIS for .NET. Armed with this knowledge, you’re now equipped to seamlessly manipulate geospatial data in your .NET applications.
