Embodiment Construction

[0035] An embodiment of the present invention provides a method for spatial location indexing. The method includes: acquiring query data reported by a terminal, determining a pre-stored first picture object according to the query data, and determining the location of the first picture object according to the first picture object. The first spatial index area at the location; according to the corresponding relationship between the spatial area range and the location data, determine the first location data corresponding to the first spatial index area; draw the first location data into the first picture object shown, and generate the first image object containing The first location data is a first picture. Through the method provided by the embodiment of the present invention, the fast response to the location data query of the monitored object and the real-time density distribution display can be realized on the map service.

Abstract

The invention discloses a spatial position indexing method and system. The method comprises the following steps: obtaining query data reported by a terminal, determining a pre-stored first picture object according to the query data, and determining a first spatial index area, where the first picture object is, according to the first picture object; determining first position data corresponding to the first spatial index area according to the corresponding relationship between the spatial area range and the position data; and rendering the first position data in the shown first picture object, and generating a first picture including the first position data. By means of the method provided in the embodiment of the invention, rapid response to position data query of a monitored object and real-time density distribution display can be realized on a map service.

Description

technical field [0001] The present application relates to the field of positioning technology, in particular to a method and system for spatial position indexing. Background technique [0002] The rapid development of computer technology brought about digitalization of information has greatly improved work efficiency and promoted social development, and at the same time, the related demand in the field of geographic information system (English: Geographic Information System, referred to as: GIS) is also increasing. Now people's requirements for map services are not limited to the display of static map data, but more and more attention is paid to the update display of real-time data. Although today's GIS system is very powerful, the rendering of front-end vector data still has performance bottlenecks such as data transmission bandwidth, data volume, and browser rendering processing capabilities. The function optimization of the open source geotools toolkit makes it easier to...
