The Vegvesen camera feed is 2D, so every camera shared one flat 150 m ground prior and mountain-pass cameras could sit hundreds of metres below the terrain where neither the point-height prior nor the ground snap resolves. Each camera now gets its terrain height from Kartverket's keyless point-height API (CC BY 4.0): ~840 of ~845 cameras. - 50 points per request, six in flight; points a full batch answers null for are retried once in batches of 10 (the API drops points from large batches). - Sea-floor depths (dybdekurver / Havflate) under bridges and quays count as the water surface, 0 m. - Heights are cached by position, so the 15-minute refresh only asks about new or moved cameras. A catalog load waits at most 12 s; a slower lookup keeps filling the cache for the next refresh. - CCTV_VEGVESEN_HEIGHTS=0 turns it off; Kartverket is credited beside Statens vegvesen in the attribution popover. Follow-up to #929. Co-Authored-By: Claude Opus 5.5 <[email protected]>
