Embodiment Construction
[0025] As shown in Figure 1, as the network release manager, first optimize the data structure of the massive spatial data (the new data structure adds the type of feature, industry of feature, important level of feature, spatial index of feature on the basis of the original data structure) , spatial density around features, etc.), and then the optimized data is processed and stored into many small data blocks according to parameters such as region, industry, and importance (according to the type of map, feature type, and Factors such as the important level of objects, the longitude and latitude of objects, the scale of map enlargement, the detailed procedures of surface objects in a unit area, etc. After detailed calculations, the map is divided into N small maps, so as to ensure that each small map is small enough for fast network transmission. In addition On the one hand, according to the longitude and latitude of the earth, the map zoom ratio, and index storage N small maps...
