METHOD AND SYSTEM FOR FORMING PARTITIONED DATA MARTS CONTAINING GEODATA AND THEIR USE IN PROCESS OF DATA STORAGE OPERATION Russian patent published in 2024 - IPC G06F7/10 G06F16/29 

FIELD: information technologies.

SUBSTANCE: invention relates to a method and system for generating partitioned data marts containing geodata. The method contains stages at which data is received as input, including: geodata, a list of numerical values from the minimum to the maximum value of the scale level of the generated data marts and a dataset with arbitrary attributes for forming a data mart. The received geodata and dataset are combined. Based on the result of the merger carried out at the previous step, tiles and their identifiers are formed for all levels of scale of the generated data marts as follows: for the current level of scale, in a cycle using tile identifiers, all data available for this tile in the combined dataset is obtained; the tiles are converted into a format for processing by the data mart and stored in the memory of the data storage device. The resulting tiles are used during the operation of the data warehouse to form partitioned data marts containing geodata in the following way: selecting the required level of scale; automatically detecting all tile IDs at the current zoom level; requesting tiles according to certain identifiers, creating and visualizing corresponding data marts.

EFFECT: increasing the efficiency of tile identification.
