This Asset include two parts, first is GIS Data Downloader which is the basec part to download and generate GIS tiles, the second is the runtime terrain streaming which is responsible to load-unload data dynamically around the player.

Once the data is downloaded via the GIS data downloader, Terrain Streaming can easily load them from StreamingAsset folder or from any location in the hard disk.

All Generated Terrains are geo-referenced automatically to WGS84, that give us the ability to Get/Set any Vector3, Transfrom or Gameobject position from/to Unity World Space <--> Real World Space.
