Incremental Updating Technique of Navigation Electronic Map Based on Spatialtemporal data model

This paper presents a technique to update navigation electronic map based on spatial-temporal data model analysis. Firstly, the technique designs the interchange format and physical format according to the traditional navigation data format. Secondly, the attributes and spatial relations incremental storing package are designed, as well as the incremental editing and checking processes, according the navigation data incremental updating service framework. Finally, focus on the partitioned data after updating, a local topology construction method is adopted by maintain the topology relationship while edit the navigation data. The platform construction of incremental updating proves the practical applicability of the technique.
