I would like to work with Cesium (www.cesiumjs.org) without any internet connection. The documentation provide a guide for working offline and prvides a way to import tiles (see https://github.com/AnalyticalGraphicsInc/cesium/wiki/Offline-Guide). However this way does not import data to be used by the TerrainProvider.
Is there a way to provide the data locally or via local cache? I know of the small terrain from http://cesiumjs.org/data-and-assets/terrain/small-terrain.html , However I need a finer terrain detail.
