,Sustained spatial data management in real-world projects — A research focus, solved. Partially in contrast to the mainstream in GIS research, the most important technical issues of real-world projects point to processes which support an efficient, economic but long living ‘data life cycle’, namely: 1. Data capturing; 2. Continuous map revision, database update and quality c
