Problems solved by technology

[0007] The present invention aims at the storage and transmission crisis caused by the current use of all geometric data storage formats, as well as the resulting increase in storage costs. The present invention proposes a multi- Block structure grid data compression storage and decompression method, by extracting the logical surface information and logical surface geometric data of a single block structure grid, encoding and compressing the geometric data of the original grid, and then storing the grid logical surface information and logical surface Geometric data, reducing the storage space of grid data, when the grid is to be used, use the corresponding decompression method to recover all grid geometric data without loss, with small storage space and high storage efficiency
