FAQ: CityGML for Nova Sofala
How is CityGML different from CityJSON?
CityGML is XML (OGC standard), CityJSON is JSON (compact). Both contain the same data.
What level of detail?
LOD 1 -- block building models with heights from OSM tags.
Which version of CityGML is produced?
CityGML 2.0 — the most widespread version, the one 3DCityDB, FME, FZK Viewer and most city platforms work with. If the receiving system expects version 3.0, the file is converted with the free citygml-tools utility.
What attributes do the buildings have?
The measured height, the number of floors and the building function code derived from OSM tags. That is enough for computations on insolation, noise and building volumes.
What goes into the file besides buildings?
Nothing: only buildings are exported. Roads, vegetation, terrain and water bodies are not included in the model — those are taken as separate layers in GIS formats.
