Zusammenfassung: | The invention provides a longitude and latitude positioning method and device, and the method comprises the steps of processing the cube projection of earth surface projection information, obtaining aplurality of square block boundaries, and obtaining the square block boundary coordinates and spatial index values corresponding to the square block boundaries according to the square block boundaries; and performing hierarchical division processing on the plurality of square block boundaries and the spatial index values corresponding to the square block boundaries to obtain a plurality of squareblock sub-boundaries corresponding to each hierarchy and square block sub-boundary coordinates and sub-boundary spatial index values corresponding to the square block sub-boundaries. According to themethod, the calculation amount is reduced, the real-time calculation of a large number of longitude and latitude coordinates with lower calculation resources is realized, and the problem of a big data application scene is solv |
