APPLY HASHING TECHNIQUE FOR SPATIAL DATA MANAGEMENT IN MOBILE MAP SYSTEM
A hash function is any well-defined procedure or mathematical function that converts a large, possibly variable-sized amount of data into a small datum, usually a single integer that may serve as an index to an array. This paper is concerned with organizing and indexing of spatial data with hashing techniques. An adaptive file organization scheme for geo tagging image from mobile mapping system. This scheme aims to locate a record on spatial database with a given key using an average of one disk access, and at most two. It also aims to process search by location and set spatial operations efficiently. Finally we demonstrate a 360 panorama caching module on internet. The caching module support street view mapping client.
