NASA combined forces with several other organizations and scanned the earth with satellites and ships and they offer (for free) bathymetric data with 30 arcsecond (~1 km at the equator) resolution of the whole world. So the oceans would be covered, and even correct elevations, say the atlas mountains in Morocco could be correctly incorporated.
I think modelling a night sky is not very difficult. You take a star map with the visible objects (or 90% of those) and model a movement over time (to model continuous, seasonal and YoY change). Those movements can be described by (somewhat complicated) functions, it should be easy to model. A 1916's night sky is different from a 1940's night sky.
I will open a new thread about this.
