I need to setup a google earth alike service, which I can self-host the elevation data and map tile data on a VPS such as EC2.
I briefly researched the following resources:
- Cesium
- OpenElevation
- OpenStreatMap
- Google Elevation API
My questions are, to name a few:
What is the relationship, if any, between these technologies/products. For example, if I try to setup up a "Cesium World Terrain" server, do I still need something like OpenElevation? Or, is Cesium already using OpenElevation as a component?
Does google offer something like "GoogleEarth javascript engine/library", which is free to deploy (as long as you don't use their servers)?
I am not asking to compare these technologies, which maybe controversial or against SO's policy, but just need help to unerstand the relationship between these technologies, and what are the pieces I need.
