The framework and key technologies of a new automatic thematic mapping system
In view of the great impact of information technology and industry needs on the content,method,form and intelligence level of thematic mapping. By summarizing and analyzing the development of visualization technology and thematic mapping technology,a new automatic thematic mapping method was proposed,and the automatic thematic mapping framework was designed and realized. Based on the research of key automation technologies such as seamless transformation of spatial data,construction of thematic application model base,design of open cartographic rule and symbol base,automatic configuration of annotation and symbols,automatic processing of cartographic element relationships,and automatic map decoration,an automatic thematic mapping system is developed. The system realized through the underlying core mapping engine and embedded plug-in development technology,which implemented the thematic map mapping process driven by spatial database and application model. A variety of thematic map mapping examples are used to verify the system,and the results show that the system can well meet the needs of thematic mapping in multiple scenarios.
