Zeng Yanwei · Geomatics & Spatial Information Technology · 2003
Spatial data quality model is advanced at first in this article.Then spatial data quality testing and evaluating work procedure is analysized.On the basis of the former discussion,general design idea,programme implementation procedure,general soft ware structure and function of Spatial Data Quality Control and Evaluating System are dissertated in detail.Key techniques of the system are also simply introduced.Lastly,future reseach direction is discussed.
