The term "fine spatial resolution" refers to a high level of detail and precision in representing or capturing an image, particularly when it comes to geographical information. Full definition
The use of ensemble modeling framework enabled to reduce modeling uncertainty and present the local variation of the processes at unprecedented fine spatial resolution. (en.ilmatieteenlaitos.fi)
They represent nearby cousins of the more distant and energetic quasars; their relative proximity to Earth permits images to be made with much finer spatial resolution than is possible for quasars. (public.nrao.edu)
