PROBLEM TO BE SOLVED: To remarkably reduce the capacity of data to be preserved and the size of a processing software by structuring information spatially referred to and cutting every geographical information into geometrical information. SOLUTION: On the first stage, the structure of object family is determined corresponding to a related application and in order to distinguish the application related to the landform information and attribute, the information provided by a source is analyzed (S01-S05). On the second step, a software for structuring is operated and respective kinds of information having the vocabulary to be identified by browsing the source are let belong to a basic family FE by a table 05 (S07-S09). Afterwards, the preparation of ordering the shape table of the family FE is constituted and when all the FE defined in advance are reviewed, ranking is completed (S18). The set formed from the shape table (main body) and the attribute table (index) composes of the block of landform information.
