What this is

A single-page viewer that overlays the live MeshCore mesh — nodes and repeaters — on top of a monochrome dark base map. The base is recoloured with terrain elevation on the fly, so height and topology are visible at a glance without losing the look of the official MeshCore map. The colour ramp rescales to whatever is in the viewport: the lowest visible point maps to the bottom of the legend, the highest to the top.

Hover any node for a quick tooltip with its role and its public-key tag (the first byte of the node's identity, shown as e.g. #C1 — MeshCore's node feed doesn't carry a human-readable name, so we surface this byte as the closest analogue). Click for the full details — coordinates, role, public-key byte, and the elevation at the node's location. The live View on MeshCore map link opens the official site centred on this node's coordinates. Click an empty area for the elevation at that point. The crosshair button under the zoom controls drops a "you are here" pin.

Notes

The role filter defaults to Repeaters — switch to All, Companions or Rooms in the top bar to see other node types. The Shade and Relief sliders tune how strongly the elevation overlay and hillshading show through. The colour ramp legend in the bottom-left shows the live min/max elevation for the current viewport.

Elevation figures come from a 30 m DEM tile pyramid and are clipped to the visible viewport before mapping to the legend, so the brightest colour always corresponds to the highest point on screen.
