Method for generating urban space big data map on basis of POI commercial form data

Abstract

The invention discloses a method for generating an urban space big data map on the basis of POI commercial form data. The method comprises the steps that names of roads in a study range are firstly acquired; according to national economy industry classification types, keywords corresponding to the types are sorted; commercial form space keywords in the study range are obtained by combining the road names with the industry keywords; the commercial form space keywords are input in a map website, precise geographical coordinate information corresponding to the commercial form space keywords in the map website is captured, and the POI commercial form data with geographical coordinates in the region range is acquired and then converted into a dot format with information; POI information dots and a space digital map of the study region are superposed through ArcGIS software, and the urban commercial form distribution space big data map is obtained. By applying the urban space big data map generated through the method, a simple and visualized model can be obtained, and through classification keyword selection in the method, not only is the systematicness of commercial form space data POI guaranteed, but also data missing is avoided.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and relates to a method for generating urban spatial big data maps based on POI business data. Background technique [0002] With the rapid development of modern information technology in recent years, digital technology and network technology have penetrated into all aspects of urban life, modern urban planning, construction and management have undergone historic changes, and the efficient sharing and operation of spatial big data has realized Co-construction and sharing of spatial data resources. The analysis and mining of big data provides a more scientific and reasonable forecast and reference for the formation and development of urban industries. [0003] POI is the abbreviation of Point of Interest, which is a kind of point data representing real geographic entities. POI generally contains basic information such as name, category, latitude and longitude, and address. The rise of PO...

Problems solved by technology

[0004] At present, there are many ways to obtain POI. However, due to the complexity of the obtained information, it cannot fully meet the needs of urban planning research, and there is no complete set of methods for the classification and selection of POI keywords in business space. standard
