<connection_status> Element

(Documentation :: Earth Files?)

The <connection_status> element controls whether or not osgEarth will connect to the Internet to fetch data. This is useful for running in a "cache-only" mode if you want to populate your local cache and run completely offline. By default, the <connection_status> is online. Setting its value to offline will inform osgEarth to avoid connecting to the Internet for data.

You can also set the OSGEARTH_OFFLINE environment variable to YES to put osgEarth in offline mode.

Example:

<map name="MyMap" type="geocentric">
  <!--Add a TMS image source-->
  <image name="TMS" driver="tms">
    <url>http://labs.metacarta.com/wms-c/Basic.py/1.0.0/satellite/</url>  
    <format>jpeg</format>
    <tile_size>256</tile_size>
  </image>

  <cache type="tilecache">
    <path>c:/osgearth_cache</path>
  </cache>

  <!--Run completely off of the cache, do not connect to the Internet-->
  <connection_status>offline</connection_status>
</map>
