Abstract

The embodiment of the invention discloses a data display method and device based on a network geographic information system. The method comprises the following steps: acquiring at least one geographicspace position and at least one attribute index; sending an acquisition request including at least one geographic space position and at least one attribute index data to a server; receiving display data returned by the server, wherein the display data comprises geographic space data corresponding to each geographic space position and attribute data corresponding to each geographic space positionand each attribute index, the attribute data corresponding to each geographic space position and each attribute index is obtained by inquiring an associated database by the server according to each geographic space position and each attribute index, and the association database is preset; and displaying the display data on an electronic map. The device is used for executing the method. According to the data display method and device based on the network geographic information system provided by the embodiment of the invention, the display efficiency of the attribute data is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of geographic information science and technology, and in particular to a data display method and device based on a network geographic information system. Background technique [0002] Geospatial data is geographic data displayed on electronic maps. With the development of information technology, the application of geospatial data is becoming more and more extensive. [0003] In the prior art, the electronic map can already be displayed through the Web (World Wide Web, referred to as the Web), that is, the electronic map can be displayed through a browser by using a Web Geographic Information System (World Wide Web Geographic Information System, referred to as WebGIS). A specific location or area can be displayed on the electronic map. When it is necessary to display the socio-economic data and other attribute data of a certain area on the electronic map, it is also necessary to first query th...
