Embodiment Construction
[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] With the existing location data of 13 million enterprises in mainland China, it is necessary to cluster the POI locations of the above-mentioned enterprises, so as to obtain the spatial distribution patterns of enterprises at different spatial scales (such as: distribution range, enterprise agglomeration and co-location patterns). Due to the huge scale of points, it is difficult for traditional clustering algorithms to cluster efficiently, and it is also impossible to obtain clustering effects at multiple data scales and observation scales. The different data scales refer to the spatial stat...
