אודות פורמט COLLADA
COLLADA (.dae) is an open XML format for exchanging 3D scenes, standardized by the Khronos Group and adopted as ISO/PAS 17506. It is older and heavier than glTF, but it remains the most reliable common language between SketchUp, Blender, Maya, 3ds Max and Google Earth — it is read practically everywhere, including old versions of programs.
A map is exported to DAE when city development is needed as an object in someone else's scene: to drop the context around a project into SketchUp, to assemble a 3D model for Google Earth, to move geometry between packages where FBX or glTF for some reason do not fit.
The output is a single .dae file: buildings extruded from OSM outlines by height or floor count, with materials colored by development type, and a flat base under them. The geometry is built in meters and centered on the selected area; there are no textures and no UV unwraps in the file — only colored materials.

מי משתמש במפות COLLADA
כיצד לייצא COLLADA
איך לפתוח לאחר הייצוא
- SketchUp — File → Import → choose the COLLADA (.dae) type; in the import settings enable merging coplanar faces so the model comes out lighter.
- Blender — File → Import → Collada (.dae); materials carry over as simple colors and can be replaced with your own right away.
- Google Earth Pro — the model is shown through KMZ: put the .dae into an archive together with a KML file that ties the model to coordinates.
- Maya, 3ds Max and Unity — import DAE out of the box; in Unity it is enough to put the file into the project folder, it will be picked up as an asset.
- Scale check — the scene is in meters; if the model arrives the wrong size, set the units in the import dialog instead of scaling the objects by hand.
