Read Buildings from Database
Read Buildings from Database tool reads building models from a 3D City Database (3DCityDB). This requires the connection of TerraScan with the 3DCityDB. The connection parameters are defined in the City databases category of TerraScan Settings.
The 3D City Database is a free geo database to store, represent, and manage virtual 3D city models on top of a standard spatial relational database. The database schema implements the CityGML standard for storing geometry and semantic information of urban objects. More information, instructions for 3DCityDB setup and examples are available on the official internet pages of 3D City Database.
You may update building models stored in a 3DCityDB by reading the models, modify them based on a newer point cloud/image data set, and write them back to the database. In this scenario, the CAD file acts only as temporary working environment. The building models are only stored in the database.
To read buildings from a 3DCityDB:
1. (Optional) Define the area for reading building models by drawing a fence.
2. Select Read Buildings from Database tool.
This opens the Read Buildings from Database dialog:
3. Define settings and click OK.
This reads the building models from the database and draws them into the CAD file. The building models are drawn according to the settings for Models to check in Building vectorization / Levels category of TerraScan Settings.

Database |
Name of the 3DCityDB as defined in the City databases category of TerraScan Settings. |
Import textures |
If on, texture images are imported as well. If off, only the geometry of the models is imported. |
Inside fence only |
If on, only building models located inside a fence are imported. This is only active if a fence has been defined before the tool is started. |
