Abstract: Spatial analysis is a data analysis technique based on the geographical location and morphological characters, which has beenwidely used inmany fields. Its efficiency is directly decided by the main operation and spatial data structure. From hashing access methods to different tree structures, provided a survey on spatial data structure and presented their characteristic through comparison between all these spatial data structures.
