TileO

COG retains source pixel values and CRS. Terrain-RGB uses 0.1 m increments; Terrarium uses 1/256 m increments; no vertical datum conversion is performed. If the TIFF does not declare a unit, confirm meters or international feet from its source before creating terrain.

Coordinates use WGS84. Height is meters above the WGS84 ellipsoid; GLB dimensions are meters.

Large models are split into spatial tiles with automatic LOD; small models stay as one tile. Completed jobs include modern 3D Tiles 1.1 and an optional B3DM compatibility download for older viewers.

Choose a GLB to read its location metadata.

Compatibility output B3DM ZIP — include 3D Tiles 1.0 compatibilityNone — 3D Tiles 1.1 only

B3DM is enabled by default for GLB jobs. It creates a separate compatibility ZIP and uses additional processing time and disk space.

Scale

Pitch (°)

Roll (°)

Use scale only when the source units are not meters.

Density keeps tiles compact and may drop features. Preserve retains more geometry detail and can produce large tiles. Both quantize coordinates.

Recommended: 75–80. Quality 100 turns on lossless mode (2–3× larger file).
