[GIS program] A_Spatial_Index_to_Improve_the_Response_Speed_of_W DL : 0: 多尺度特性是指地图比例尺决定着地图显示内容的详略.基于R-tree的数据访问方法与多尺度性和成批性不相适应,存在“同级要素弱簇聚”和“I/O粒度偏小”两大问题- The access method based on R-tree is not adaptive to the multiscale and batch feature. It has two problems: (1) the data records of features of the same level are not clustered in disks (2) the granularity of data I/O is too small.
