The development of 3D engines in the field of spatial information systems leaves several open questions regarding the added value of a 3D representation of an information system within engines. On the one hand, engines such as UNITY or UNREAL allow the integration of information system providers such as ESRI or Mapbox within the engine, on the other hand, using the API key from MapTiler or Mapbox API opens many other doors inside web-based interactive computing platforms. The first question is why do we actually need an information system inside a computer game engine? The second question is what can we do with all that data in a computer game engine?
The amount of tools for GIS processing is few in computer game engines, when it comes to remote sensing, then it is generally difficult to find something that would be equivalent to the tools available in, say, geemap, but on the other hand, game engines have much more powerful computer vision capabilities, since the interface with the whole subject of virtual reality And the layer, GIS, external software, electronic sensors, opens doors to much more complex systems than GIS or remote sensing systems, simulation and control systems, which at this stage are difficult to think of, or to describe, but which are definitely possible and can be very powerful.
