# **WorldWind Explorer**
The [__Explorer__](https://worldwind.earth/explorer) is an HTML5/JavaScript geo-browser
_[powered by WorldWindJS](https://worldwind.earth/worldwindjs/)_ and the Knockout and Bootstrap libraries.
It is implemented as a single-page web application (SPA) using JQuery to dynamically load content.
## Overview
The _WorldWind Explorer_ is a geospatial web application for visualizing Earth. It uses the
WorldWindJS library (forked from the NASA WebWorldWind 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.

# ***NASA WorldWind Project Suspension***
NASA announced a impending shutdown on March 8, 2019:
> WorldWind team would like to inform you that starting May 3, 2019, NASA WorldWind project will be suspended.
>
> All the WorldWind servers providing elevation and imagery will be unavailable. While you can still download the SDKs from GitHub, there will be no technical support. If you have questions and/or concerns, please feel free to email at: [[email protected]](mailto:[email protected])
## WebWorldWind
Here is important information for mitigating issues caused by the shutdown in NASA Web WorldWind SDK based applications. The ramifications of the suspension are severe, including:
- **Critical:** Web applications linked to _https://files.worldwind.arc.nasa.gov/artifactory/web/0.9.0/worldwind.min.js_ will fail if the _files.worldwind.arc.nasa.gov_ server is shutdown. ___The globe will not be displayed.___ Applications that use a local copy of _worldwind.js_ or _worldiwnd.min.js_ should continue to work, but image resources linked to "files.worldwind..." will not be displayed (e.g., the globe background, view controls, compass, etc.).
- **Severe:** Working web applications that use the built-in elevation services at https://worldwind26.arc.nasa.gov/elev will display a smooth globe – ___3D terrain visualizations will not work and all earth elevations will be zero.___ This will affect nearly every WorldWind-based web application.
- **Caution:** Working web applications that use the built-in imagery from https://worldwind25.arc.nasa.gov/wms ___will no longer have access to the Blue Marble and Landsat base map layers.___ Layers from other source should still work (e.g., Bing, USGS National Map, etc.)
### Alternatives to files.worldwind.arc.nasa.gov
If the _files.worldwind.arc.nasa.gov_ service is offline, an alternative source for the 'worldwind.js' library is required.
#### Use the WorldWindJS library
{:.no_toc}
The WorldWindJS library is designed as a drop in replacement for `worldwind.js` (and `worldwind.min.js`). Here are two implementations
for using WorldWindJS.
**For npm based applications:** change the `@nasaworldwind/worldwind` dependency to `worldwindjs`. For example:
_Example: Original package.json_
```
"dependencies": {
"@nasaworldwind/worldwind": "^0.9.0"
},
```
_Example: New package.json_
```
"dependencies": {
"worldwindjs": "^1.7.0"
},
```
**For scripts:** change the src from _files.worldwind...worldwind.js_ to WorldWindJS' npm-based CDN at _unpkg.com_:
_Example: Old script element, using files.worldwind.arc.nasa.gov_
```
```
_Example: New script element, using WorldWindJS at unpkg.com_
```
```
#### Use NASA's WorldWind library from a CDN
{:.no_toc}
Change script element's src from _files.worldwind_ to the npm-based CDN at _unpkg.com_ :
_Example: Old script element, using files.worldwind.arc.nasa.gov_
```
```
_Example: New script element, using unpkg.com_
```
```
#### Use the Web WorldWind source code
{:.no_toc}
Deploy the Web WorldWind source code, either directly or in compiled form, to your web server.
This solution is the most flexible as it provides the capability to customize the sources for
resources, imagery and elevations, and it ensures any changes at NASA or WorldWind Earth do not
have a direct affect your project's runtime.

### Alternatives to using WorldWind Elevations
I have an alternative server for NASA elevations (from [worldwind26.arc.nasa.gov/elev](https://worldwind26/arc/nasa.gov/elev))
staged for production should the WorldWind shutdown become a reality. I will make this server available if needed.
#### Use the WorldWindJS library
{:.no_toc}
The WorldWindJS library v2.0 (to-be-released) does not have dependencies on the NASA elevation services.
I have been beta-testing the serving of `application/bil` elevations from my own servers (which I pay for out of pocket).
If/when a shutdown becomes imminent I will transition WorldWindJS to use my servers.
#### Build your own elevation server
{:.no_toc}
- [Elevation Server](elevation-server.md) - How to create a WorldWind elevation server
- [Elevation Data](elevation-data.md) - Sources for elevation data and conversion scripts
#### Change the source to use other elevation services
{:.no_toc}
Here's an example for using alternative elevation services. In this example, two custom elevation coverages
are defined, a custom elevation model is then defined, and finally, the WorldWindow is configured with the
custom elevation model.
Example: a custom GEBCO elevation coverage class:
```
/**
* @exports MyGebcoElevationCoverage
*/
define(['worldwind'],
function (WorldWind) {
"use strict";
/**
* Constructs an Earth elevation coverage using GEBCO data.
* @alias MyGebcoElevationCoverage
* @constructor
* @augments TiledElevationCoverage
* @classdesc Provides elevations for Earth. Elevations are drawn from the custom elevation service.
*/
var MyGebcoElevationCoverage = function () {
WorldWind.TiledElevationCoverage.call(this, {
coverageSector: WorldWind.Sector.FULL_SPHERE,
resolution: 0.008333333333333,
retrievalImageFormat: "application/bil16",
minElevation: -11000,
maxElevation: 8850,
urlBuilder: new WorldWind.WmsUrlBuilder("https://mapserver.somewhere.net/elev", "gebco", "", "1.3.0")
});
this.displayName = "GEBCO Earth Elevation Coverage";
};
MyGebcoElevationCoverage.prototype = Object.create(WorldWind.TiledElevationCoverage.prototype);
return MyGebcoElevationCoverage;
});
```
Example: a custom SRTM elevation coverage class:
```javascript
/**
* @exports MySrtmElevationCoverage
*/
define(['worldwind'],
function (WorldWind) {
"use strict";
/**
* Constructs an Earth elevation coverage using CGIAR SRTM data.
* @alias MySrtmElevationCoverage
* @constructor
* @augments TiledElevationCoverage
* @classdesc Provides elevations for Earth. Elevations are drawn from the custom elevation service.
*/
var MySrtmElevationCoverage = function () {
WorldWind.TiledElevationCoverage.call(this, {
coverageSector: new WorldWind.Sector(-60, 60, -180, 180),
resolution: 0.000833333333333,
retrievalImageFormat: "application/bil16",
minElevation: -11000,
maxElevation: 8850,
urlBuilder: new WorldWind.WmsUrlBuilder("https://mapserver.somewhere.net/elev", "srtm-cgiar", "", "1.3.0")
});
this.displayName = "SRTM-CGIAR Earth Elevation Coverage";
};
MySrtmElevationCoverage.prototype = Object.create(WorldWind.TiledElevationCoverage.prototype);
return MySrtmElevationCoverage;
});
```
Example: a custom elevation model class that uses the custom coverages:
```javascript
/**
* @exports MyElevationModel
*/
define([
'model/globe/elevations/MyGebcoElevationCoverage',
'model/globe/elevations/MySrtmElevationCoverage',
'worldwind'
],
function (MyGebcoElevationCoverage,
MySrtmElevationCoverage,
WorldWind) {
"use strict";
/**
* Constructs an MyElevationModel consisting of two elevation coverages GEBCO, SRTM.
* @alias MyElevationModel
* @constructor
*/
var MyElevationModel = function () {
WorldWind.ElevationModel.call(this);
this.addCoverage(new MyGebcoElevationCoverage());
this.addCoverage(new MySrtmElevationCoverage());
};
MyElevationModel.prototype = Object.create(WorldWind.ElevationModel.prototype);
return MyElevationModel;
});
```
Example: the function for creating a `WorldWindow` with the custom elevation model:
```javascript
var wwd = new WorldWind.WorldWindow("globe-canvas", new MyElevationModel());
```

### Alternatives to using WorldWind Imagery
I have an alternative server for NASA core imagery (from [worldwind25.arc.nasa.gov/wms](https://worldwind25.arc.nasa.gov/wms))
staged for production should the WorldWind shutdown become a reality. I will make this server available if needed.
#### Use the WorldWindJS library
{:.no_toc}
The WorldWindJS library v2.0 (to-be-released) will not have dependencies on the NASA imagery services.
I have been beta-testing the serving of Blue Marble and Landsate imagery from own servers (which I pay for out of pocket).
If/when a shutdown becomes imminent I will transition WorldWindJS to use my servers.

## WorldWindJava
I have alternative servers for NASA core imagery (from [worldwind25.arc.nasa.gov/wms](https://worldwind25.arc.nasa.gov/wms))
and NASA elevations (from [worldwind26.arc.nasa.gov/elev](https://worldwind26.arc.nasa.gov/elev)) staged for production should the WorldWind shutdown become a reality. I will make these servers available if needed.
To leverage these servers, you will need to alter the URLs in the [`src/config/config.Earth`](https://github.com/WorldWindEarth/WorldWindJava/tree/develop/src/config/Earth)folder.
