In recent years, cloud computing has become the most dazzling star in the IT industry. From initial conceptual hyping to gradually being accepted by users, it has developed rapidly in some key industries, the wide scope of impact is staggering.
When everyone is thinking about how to use the cloud computing service and how to enjoy the value brought by the cloud computing service, cloud GIS appears in front of everyone, because:

When you do it, realize that the so-called scramble actually have two possible types, one is the two sub-nodes in the lower layer of the swap, such as if we from the first layer of segmentation point, or from the higher layer of the segmentation point of view, The substring on the left side of the S1 and S2 points should have exactly the same num
