Hybrid DTED terrain source (local + remote): 3D vertex elevation from DTED and 2D hillshade overlay with DT2 > DT1 > DT0 precedence.

Fog, night imagery, water mask, atmosphere configuration for 3D globe rendering with live config preview.

Vector features on 3D globe — world cities, flight routes, and continental regions with shader projection.

3D globe mode with pitch/bearing, OSM tile projection on unit sphere, and animated camera flights.

TileJSON terrain source with 3D vertex displacement and optional 2D hillshade overlay.

Interactive drawing: Point, Polyline, Polygon placement with vertex editing. Undo/redo, toolbar widget, 2D/3D.
