Non-georeferenced screenshots

Plain screenshots with no metadata, processed at an assumed 0.5 m GSD. The output is an rDSM, and its metric scale is only as good as that assumption.

High-rise district: input, height map, 3D render — High-rise district (v3). Colour scale 0–112.4 m. Each panel shows the input, the predicted height map and a textured 3D render from the viewer.Imagery © Google Earth.

Stadium and domed hall: input, height map, 3D render — Stadium and domed hall (v3). Colour scale 0–18.7 m. The curved roof and the stands are recovered as smooth surfaces.Imagery © Google Earth.

v3 vs v4

Same scene predicted by v3 and v4-modal — Same scene, same 0.5 m GSD. Left: input. Centre: v3 height map (0–30.8 m) and 3D render. Right: v4-modal (0–59.3 m), which flattens the surrounding tree canopy to zero height. This was the visual symptom of v4's flat-ground trade-off; see Design findings.Imagery © Google Earth.

Cartosat-2E, georeferenced (absolute DSM)

A 1024 × 1024 px Cartosat-2E crop at 0.6 m (EPSG:32644, village and scrubland), processed by v5 with absolute enabled. The nDSM maxes out at 11.8 m and 92.3 % of pixels are below 1 m, as expected for a sparse rural scene. The DSM combines the DEM-anchored terrain with the nDSM, in metres above EGM2008.

Input (bands 3-2-1) — Classes use the app palette: tan = ground, light green = low vegetation, red = building, blue = water, dark grey = road, light grey = other, dark green = tree. Job 88e63fd3329e.

nDSM 0–3.5 m (p98) — Classes use the app palette: tan = ground, light green = low vegetation, red = building, blue = water, dark grey = road, light grey = other, dark green = tree. Job 88e63fd3329e.

Cartosat-2S campus sample

Infosys campus, Bhubaneswar, in the DepthWizard web app with extracted buildings, OSM roads and a hover card — **In the full web app:** Infosys campus, Bhubaneswar (Cartosat-2S, 0.6 m, georeferenced). Buildings are extracted as 3D objects and OpenStreetMap roads are overlaid. The hover card reads a 17.0 m building (about 5 floors, 94 × 111 m footprint). You can explore this scene interactively on the docs home page. Google Maps · Source imagery: Bhoonidhi

The sample scene bundled with the web app (File → Sample scenes): a large campus with detached buildings.

Synthetic test scene

A synthetic city with exact block heights of 24, 11, 38, 8, 17, 6, 30 and 13.5 m, used to test the viewer and the evaluation code end to end.
