The paper describes basics of high-level management model and technology for dealing with large distributed human or technical systems which can be represented as dynamic physical-virtual networks covering any terrestrial or celestial environments. The main technology component, Spatial Grasp Language (SGL), allows us to obtain powerful and compact spatial solutions of different problems by directly expressing their top semantics while hiding traditional system organization and management routines inside efficient networked implementation. Different network creation, evolution, matching, and transformation approaches are investigated and shown in SGL on general networks, which may be practically useful in a variety of areas influencing the dangerously growing world dynamics and caused, for example, by climate change, military, religious and ethnic conflicts, terrorism, refugee flows, weapons proliferation, political and industrial restructuring, growing inequality, economic instability, global insecurity, and very recently, due to the world-wide pandemic horror.
