Topographic Field Map

A three-dimensional terrain view of one measured layer, where the height of the surface at each point shows the field strength measured there. Each measured layer, from the accessory surface to the deepest scanned plane, is its own map, and the accessory is drawn at true scale beneath the terrain for reference. Reading it is like reading elevation on a landscape map: peaks rise over the strongest field, and looking straight down at it gives the same picture as the Heatmap. Height uses the same logarithmic scale as the Heatmap, so the faint field between a mat's coils stays visible as low relief instead of flattening out; the map reaches past the accessory's edge only when enough points were measured out there, and otherwise it stops at the edge rather than guess the shape between a stray reading or two. The colors fade through the same thermal ramp over each setting's own peak, with red at half that peak, white only at the peak, and the zero-field ground in black. Height here means field strength, while the Field Volume dome's height means physical distance, so the two shapes differ by design even though they are built from the same measurements.
