Research for Partition Pretreatment Technology of Mining Area GIS Large-scale Node
Xiaoxin Du · Coal Technology · 2013
A partition pretreatment algorithm of mine area GIS R tree large-scale node is put forward.This algorithm can guarantee the geometry shape of node better and reduce overlap which appears when inserting node after partition.A series of tests indicate that the algorithm improves the query efficiency of spatial data when the cut algorithm is executed.
