Cheng‐Zhi Qin · Geo-information Science · 2006
Spatial data warehouse is the extension of data warehouse on the basis of spatial data. Building seismic spatial data warehouse is important for studying the law of seismic activity in time sequence, spatial area, and spatio-temporal distribution, as well as earthquake forecast, prevention and reduction. Earthquake happens very frequently in North China. Its seismic data records are superior to other areas of China in aspects of precision, quantity, and perfection. So the authors tried to build a seismic spatial data warehouse of North China for the study of the method of building spatial data warehouse.
