The application discloses a kind of based on GiST spatial index multi-resolution fragmentation DEM database construction method, comprising: S1, with the resolution of fragmentation DEM image tile as hierarchical division standard;S2, existing DEM image tile is hierarchically divided according to S1 hierarchical division standard, to minimum outer rectangle as unit independent storage;S3, based on DEM image tile, the hierarchical structure rule of R tree is used to establish parent-child node relationship, and the initial R tree multi-resolution skeleton is constructed;S4, on the basis of initial R tree multi-resolution skeleton, uniform different hierarchical spatial relationship description rule is formulated, and according to the rule, the spatial correlation between DEM image tile is described, and the preliminary establishment of multi-resolution DEM database based on GiST spatial index is completed;S5, the DEM image tile to be stored is stored into database, and the database is improved.The application improves the performance of DEM data storage.

This invention discloses a method and related equipment for function calls in SO files, relating to the field of information security. The method includes: parsing and obtaining function call information for all first SO files; establishing a mapping relationship between encrypted names and second names; creating a second function in a second SO file based on the mapping relationship; replacing the first name of each first SO file with the name of the second SO file; and replacing the second name of each first SO file with the name of the corresponding second function. This invention addresses two main problems associated with function calls in SO files: firstly, the significant burden on developers due to special code modifications during development; and secondly, the inconvenience of subsequent statistical analysis and searching of system function calls.
