You better have an idea about GPX files that contain geospatial data which consists of location and attributes. Somehow, you need a third-party GIS software to view/read GIS data. Therefore, this blog post will teach you how to view GPX file using an online Map viewer and also you will learn how to achieve geospatial data visualization in C# programmatically. Moreover, you will be able to build a GIS data viewer for your business application using a C# GIS library. Aspose.GIS for .NET provides a complete solution to automate the process of reading a GPX file in C#. Sufficient explanation has been provided, let us now implement the functionality.
We will cover the following items in this article:
- Online Map Viewer - Live Demo
- C# GIS Library Installation
- Geospatial Data Visualization in C# - Code Sample
Online Map Viewer - Live Demo
This online GIS data viewer works on both desktop and mobile phones and is powered by Aspose.GIS. It supports multiple GIS file formats such as GPX, OSM, CSV, and many more. All you need to do is to drop your GIS file and this online map viewer will render the Geo data in the shortest period.
In addition, you can save and download the geographical data in multiple image formats. This geospatial data visualization tool also lets you configure the rendering options so that you can get the geospatial data visualization of your activities such as walking, driving, or running. The user interface is user-friendly with a nice drag & drop space. Above all, it is free and there is no fee attached to its usage.
C# GIS Library Installation
Earlier we walked through a non-programmatic solution, now we will head to a C# GIS library to read a GPX file in C# application. So, this is an enterprise-level .NET library with a wide stack of classes and methods to render GIS data files. For the installation of Aspose.GIS for .NET, you can either download the DLL file or run the following command into NuGet Package Manager.
Install-Package Aspose.GIS
Please check out the installation page to walk through all the installation details.
Geospatial Data Visualization in C# - Code Sample
Now, we can start making API calls to build a GIS data viewer. Please be mindful that we have a source GPX file for the implementation.
You can follow the steps mentioned below:
- Load the GPX file by calling the OpenLayer method.
- Loop through all the opened layers.
- Check the type of the geometry(GeometryType) if it is Point.
- Create an object of the Point class and initialize it with the retrieved point.
- Now, print waypoints from the GPX file.
- Again, check if the type of the geometry(GeometryType) is LineString.
- Instantiate an instance of the LineString class and initiate it with the retrieved routs.
- Print the Routs from the GPX file.
- See if the type of the geometry(GeometryType) is MultiLineString.
- Read the track from the GPX file and print.
The following code snippet demonstrates how to read a GPX file in C# programmatically:
