Feature count: text overlay
Permanent corridor labels for the public grid overlay, separated from river labels to reduce low-zoom clutter.
Summary
This layer provides permanent text labels for major transmission corridors in the public grid overlay. It is separated from river labels so grid-oriented map views can retain their own visual hierarchy.
What It Represents
This overlay labels the major transmission network directly on the map. It is separated from river labels because the grid story needs its own visual hierarchy.
How To Read It
Use it when the map is being used to explain grid bottlenecks rather than hydrology. Labels are sourced from the major transmission network only, not from QA fragments or the conceptual spine.
Coverage / Method
The layer is a text overlay documented in Map Inventory. Labels are derived from the major transmission network presentation layer and are not generated from internal QA fragments or conceptual-spine layers.
Caveats
Transmission labels are only as good as the underlying corridor abstraction. They help orientation, but they do not add new geometry or confidence.
