Terrain probes draw from mid zoom (≥ 13) inward; picking a site flies in to show them.
LINZ Basemaps key⚙
Free key: basemaps.linz.govt.nz — aerial, topographic raster and the elevation DEM (Mh) all load keyless (rate-limited); a key adds higher rate limits and the vector-topo labels in the 3D view. Shares the key with the Wind tool.
LRIS / LCDB key (optional)
Enables LCDB land-cover terrain auto-classification (LCDB v6.0 WFS).
Terrain probes — 8 upwind sectors (±22.5°)
TC1 — open/smooth (water, sand, crops)
TC2 — open (grassland, farmland)
TC2.5 — scrub / parkland
TC3 — suburb / plantation
TC4 — rough (native forest, dense urban)
no mapped land cover at probe
Probes with no LCDB class that sit at
DEM sea level (≈0 m) count as open water TC1 — rough LINZ DEM check.
Dot = most-severe class hit at that probe.
The governing direction's sector is drawn stronger.
