8. Information systems to manage urban data Urban data are created and managed with several information systems. The two main ones are: Geographical Information Systems (GIS) and Computer Aided Design Systems (CAD) Roads 3D Buildings Rivers Cadastre Traffic Data Weather Data Pollution Data Managed by GIS Managed by CAD
16. A raster or a vector file can be exchanged between geographical information systems, and vector file attributes can be reached through a database Raster file Vector file Geographical Information System (GIS) Geographical Information System (GIS) RDBMS
17. A standard GML file can be exchanged between GIS Geographical Information System (GIS) Geographical Information System (GIS) GML file
18. The raster/vector/GML files and related attribute databases can be reached by APIs Raster file Vector file GML file Application Programming Interface (API) Any Application
19. The raster/vector/GML files can be stored in a spatial database Spatial Database Raster file Vector file GML file
