Multi-relational spatial data mining method based on S-CART decision tree
|
Abstract:
Regarding the complicated relationship existing in the spatial data,a kind of improved arithmetic based on the S-CART was presented.In this arithmetic,firstly,the relational atoms propositions from different thematic layers were drawn by the Spatial Jion Index Table(SJIT).And then,based on the predicates,a multi-relational binary decision tree was established and the spatial association rules were drawn out.The efficiency of this arithmetic is validated based on the soil pollution data of some areas of Daye...
