Abstract

Data pre-processing is an important step in data mining. Special method is usually used in spatial data pre-processing because complex spatial data easily bring about the case of inconformity and spatial data in different application has its own characteristic. In this paper，an effective method was presented to solve the problem of inconsistent spatial object’s location which was produced in the process of sub-compartment digitalization. The method was based on a referent graphic surface through the two outermost points of intersection，and the subcompartment could be amended at the all intersection points. Compared with conventional methods （point capture），the proposed approach had a better effect.［Ch，7 fig. 10 ref.］
