Reading “ceiling 300 m” in a table says little about the margin you really have. The 3D view renders the terrain under your mission area, SIA airspace as volumes extruded between their floor and ceiling, and your flight height above it — so you see the constraint instead of deducing it.
Terrain is rendered from the Cesium World Terrain elevation model, with OpenStreetMap imagery. A zone on a hillside does not read like a zone on flat ground: the height difference under your polygon becomes visible, and with it the drone's real height above ground throughout the mission.
Each SIA zone is extruded between its published floor and ceiling — cylinders and sectors are overlaid on the terrain at their real altitude. You immediately see whether a CTR passes above the area without constraining it, or comes down to the ground.
Mission height is expressed in metres AGL (30 to 120 m), while airspace floors and ceilings are published as AMSL altitudes and rendered as such. Overlaid on the terrain, the two can be compared visually — it is the real margin, not an isolated number.
When a zone's floor or ceiling is unusable, it is not drawn at an invented altitude: it is draped on the ground and displayed distinctly, so uncertainty stays visible instead of being hidden by a false volume.
3D makes the terrain, your mission height and the airspace floors/ceilings visible. It helps you understand the real margin available instead of just reading a constraint in a table.
No. The 3D view is a graphical representation of airspace and terrain data. Official publications and the remote pilot's obligations take priority.
The zone stays flagged and is not drawn at an invented altitude. Uncertainty must remain visible to avoid an over-optimistic interpretation.
Before interpreting terrain and volumes, first check the zone constraints and the weather slot of the planned flight.
