| 主权项 | 1. A method of compressing spatial data comprising: (a) determining the size of actual data of the spatial data stored in a unit storage space having a predetermined size; (b) selecting the size of a compression storage space in which the spatial data is to be compressed and to be stored, in consideration of the determined size of the actual data of the spatial data; (c) generating flag information considering the size of the actual data of the spatial data; and (d) storing the generated flag information in a predetermined region of the compression storage space having the selected size and storing the actual data of the spatial data in the other regions of the compression storage space. | ||
