CC BY 4.0 requires indicating whether the licensed material was modified. NOTICE credited the source of each test seed in testdata/ but did not say how the seed differs from it.

Each geometry entry now has a Changes: line: imported into 3DCityDB with citydb-tool, reduced to a subset of buildings, exported as a PostgreSQL dump, coordinates left in the source reference system, no other edits.

Seed Source format Buildings Reference system
Germany CityGML 259 EPSG:25832
Austria CityGML 51 EPSG:31256
Netherlands CityJSON 246 EPSG:28992

Building counts are objectclass_id = 901 rows in each seed's lod2.feature; reference systems are from each seed's lod2.database_srs.

NOTICE credited the Bavaria, Vienna and 3DBAG sources of the test seeds
but did not say that each seed was imported into 3DCityDB, cut to a
subset of buildings and exported as a PostgreSQL dump. Each entry now
carries that statement, with the building count and the unchanged
source reference system.
