| Abstract;Geographic information consists of a large amount of data, and a search through it tends to take much time. In a geometric application, however, a need often arises for a search by the region or a search by the category associated with each data item. Here we consider a method of storing geographic data which lends itself to the efficient retrieval of the stored data. In particular, a set of character data associated with points is taken as a sample data set. We propose a method of (I) managing the point-associated data in terms of the unit area of a certain extent, and (II) adding an index to each unit area categorizing the type of data residing in that area. Feasibility of the proposed method is evaluated through experimentation. (author abst.) |
