Introduction

In the realm of geospatial visualization, World Wind Java (WWJ) has emerged as a powerful tool for displaying and interacting with geospatial data. One of the key features of WWJ is its ability to display KML (Keyhole Markup Language) files, which are widely used for geospatial data representation. In this article, we will delve into the world of World Wind Java KML Viewer, a software project that provides a KML layer and a viewer application for WWJ. We will explore the two main components of this project, discuss their features, and provide a comprehensive guide on how to use them.

What is World Wind Java?

World Wind Java (WWJ) is an open-source, Java-based geospatial visualization platform that allows users to display and interact with geospatial data. It is built on top of the World Wind SDK, which provides a set of APIs and tools for creating geospatial applications. WWJ is designed to be highly customizable and extensible, making it an ideal choice for developers who want to create complex geospatial applications.

What is KML?

KML (Keyhole Markup Language) is an XML-based file format used for geospatial data representation. It is widely used for displaying geospatial data in Google Earth and other geospatial applications. KML files can contain a variety of data, including points, lines, polygons, and other geometric shapes, as well as metadata such as labels and descriptions.

World Wind Java KML Layer

The World Wind Java KML Layer is a software component that allows users to display KML files in WWJ. It is designed to be highly customizable and extensible, making it an ideal choice for developers who want to create complex geospatial applications. The KML Layer provides a range of features, including:

KML file loading: The KML Layer can load KML files from a variety of sources, including local files, URLs, and databases.
KML file parsing: The KML Layer can parse KML files and extract the relevant data, including points, lines, polygons, and other geometric shapes.
KML file rendering: The KML Layer can render KML files in WWJ, using a range of rendering options, including 2D and 3D rendering.
KML file interaction: The KML Layer provides a range of interaction options, including zooming, panning, and clicking on KML features.
