Invokes Web WorldWind without using the Internet. Refers to data stored only on a local environment.
|
|
|
|
To deploy:
|
|
|
|
- Download https://files.worldwind.arc.nasa.gov/artifactory/standalone-data/WebWorldWind-StandaloneData.tar.gz and unzip it
|
|
so that the "standalonedata" directory is a peer of the 'apps' folder. It contains the Blue Marble imagery,
|
|
the Landsat imagery and the DTED0 elevations in its Earth directory.
|
|
|
|
- The worldwind.min.js file location in this file is assumed to be where the library is compiled given the repository
|
|
build process, and it can be modified as needed.
|
|
|
|
- Ensure that your web server is configured to send an HTTP content type of application/octet-stream
|
|
or application/bil16 for files with a .bil suffix. You can do this for Apache servers by adding bil
|
|
to the list of application-octet-stream suffixes in the mime.types file and then restarting the server.
|
|
|
|
- Use your browser to invoke this HTML file, the one you're now reading, via the web server. Do not attempt
|
|
to open it using the browser's File->Open menu. Use an http or https URL with the server address.
|
|
|
|
If deployment was successful then you should see a Web WorldWind globe in the browser. The globe
|
|
should have Blue Marble imagery all over it and greenish Landsat imagery over most of North America.
|
|
|
|
If you zoom into a mountainous region you should see the raised mountains. There are no elevations
|
|
included for the oceans, so they are all flat.
