Urban spatial feature region automatic division system

Abstract

The invention discloses an urban spatial feature region automatic division system, which comprises: a user side used for acquiring form content filled by a user; the browser that is used for splicing form contents into a long character string and transmitting the long character string to the background server along with clicking of a submission button by a user; the network server that is used for processing the request of the browser and returning a corresponding response; the background server that analyzes the received character string and executes geographical calculation in the background; after calculation is completed, the position and the file name of the generated ShapeFile compressed file are transmitted to a browser; and the browser analyzes the received data, converts a ShapeFile compressed file into a GeoJson format, and superposes a result calculated by the background server on a base map of a map on the right side of a browser page for display. The invention has the remarkable effects that a plurality of region division algorithms are designed, results can be compared, and an algorithm which is more suitable for actual region division is selected.

Description

technical field [0001] The invention relates to the technical field of urban geographical management, in particular to an automatic division system for urban spatial characteristic areas. Background technique [0002] With the continuous increase of the urban population and the continuous expansion of the city scale, more and more areas need to be controlled by the government, and the contradiction between urban planning and urban development has become increasingly prominent. How to improve the quality of urban planning under the new development situation? Planning data at all levels is an important issue facing urban planning. But at present, city managers do not make full use of various urban planning data, and mostly use manual processing, which is inefficient. At the same time, urban geographic information systems have been greatly developed and widely used in recent years. Computer technology, especially Web technology, and corresponding front-end and back-end interac...

Problems solved by technology

[0005] At present, the main problems in urban zoning: (1) The zoning idea is mainly static, and the static information such as POIs is directly clustered to complete the zoning; (2) Static data such as POIs are first classified, and then the classified POIs are used to (3) cluster the trajectory data, use the cluster center to construct the Voronoi diagram, and complete the partition

Therefore, the partition results under the guidance of the static partition idea have certain limitations

In addition, the grid management mentioned above is more focused on the efficient management of the city, while the division of urban functional areas based on traffic big data is more biased towards the research of algorithms. The processing method and process of GIS system in big cities
