Abstract
A spatial LSM tree apparatus includes: a blockchain configured of a plurality of data blocks each storing point data distributed over an entire spatial area; a memory unit including a component table storing information about a memory component storing a first index of a most recently stored point data in the blockchain and all components of a spatial LSM tree indexing the point data to cover the entire spatial area; and a disk unit storing a secondary index for the point data in chronological order stored in the blockchain through a plurality of disk components formed in a hierarchical structure among a plurality of levels.
