Uses latitude and longitude locations of people logged into Kaseya.

Visual Globe

Written by Adam Booth using the following libraries and files. Quick little side project I decided to look into. The latitude and longitude points I worked with were provided by Kaseya, a remote desktop client used at my workplace. We had other previous visuals so we could see logged in users across the US, but I thought this might be interesting and it was. Project is now closed.

The Following is provided with the standard WebGL Globe library.

The WebGL Globe is an open platform for visualizing geographic information in WebGL enabled browsers. It supports data in JSON format, a sample of which you can find [here] (https://github.com/dataarts/dat.globe/raw/master/globe/population909500.json). dat.globe makes heavy use of the Three.js library, and is still in early open development.

Data Format

The following illustrates the JSON data format that the globe expects:

var data = [
  [
    'seriesA', [ latitude, longitude, magnitude, latitude, longitude, magnitude, ... ]
  ],
  [
    'seriesB', [ latitude, longitude, magnitude, latitude, longitude, magnitude, ... ]
  ]
];

Basic Usage

The following code polls a JSON file (formatted like the one above) for geo-data and adds it to an animated, interactive WebGL globe.

// Where to put the globe?
var container = document.getElementById( 'container' );

// Make the globe
var globe = new DAT.Globe( container );

// We're going to ask a file for the JSON data.
xhr = new XMLHttpRequest();

// Where do we get the data?
xhr.open( 'GET', 'myjson.json', true );

// What do we do when we have it?
xhr.onreadystatechange = function() {

  // If we've received the data
  if ( xhr.readyState === 4 && xhr.status === 200 ) {

      // Parse the JSON
      var data = JSON.parse( xhr.responseText );

      // Tell the globe about your JSON data
      for ( i = 0; i < data.length; i++ ) {
        globe.addData( data[i][1], 'magnitude', data[i][0] );
      }

      // Create the geometry
      globe.createPoints();

      // Begin animation
      globe.animate();

    }

  }

};

// Begin request
xhr.send( null );
