Explorer Project

The Explorer is an HTML5/JavaScript geo-browser powered by NASA Web WorldWind and the Knockout and Bootstrap libraries. It is implemented as a single-page web application (SPA) using JQuery to dynamically load content.


The WorldWind Explorer is a geospatial web application for visualizing Earth. It uses the Web WorldWind JavaScript SDK to display a 3D globe with terrain and imagery as well as 2D maps. It displays the sunrise and sunset times and solar angles for any point on the earth. It shows the terrain’s aspect and slope for any location. It features user-defined markers and point weather forecasts. It has a search feature to find places.
