I am working on an application that requires the following terrain data:
On the one hand, some surfaces have to be planar (e.g. runways)
On the other hand, I still want to have some 3D structure (e.g. mountains)
Unfortunately, I have not discovered a terrain provider that fulfills both requirements at the same time. Either the runways are no really smooth or then there are no terrain data at all.
So my question is: Is it possible to use a standard locally flat WGS84 for a confined area (i.e. an airport), and another provider for the rest to have the 3D impression?
Thank you very much!
PS: Or is there high resolution provider around? With a comparable to google earth? I haven’t discovered a service offered by google to connect with cesium. I assume that there is no such service anymore since the shutdown of GEE, right?
