Abstract
Provided are an apparatus and method of compressing spatial data and an apparatus and method of restoring compressed spatial data, the method of compressing spatial data including: determining the size of actual data of the spatial data stored in a unit storage space having a predetermined size; 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; generating flag information considering the size of the actual data of the spatial data; and 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.
