Design Principle
Geospatial interfaces depend on synchronization between location, scope, objects, and selection state.
Principle Geospatial interfaces depend on synchronization between location, scope, objects, and selection state.
Design action Map, result list, filters, and detail panel share selected state; map controls must not cover important areas.
Examples Positive example: Store, delivery, listing, event, logistics, or geodata pages need comparison between map and list. Counterexample: The map fills the page without list or filter feedback.
Apply when Store, delivery, listing, event, logistics, or geodata pages need comparison between map and list. Users need to judge state, scope, risk, or next action quickly.
Source notes Source note: Synthesized from Apple HIG, Material Design, NN/g usability principles, and layout/hierarchy practices in mature design systems.
