Geographic space data service integrating method of dynamic configuration oriented to mobile client side

Abstract

The invention discloses a geographic space data service integrating method of dynamic configuration oriented to a mobile client side. The method includes the following steps of firstly, defining an XML configuration file template to regulate the structural and universal parameters of a dynamic configuration file; secondly, analyzing and collecting the types of existing geographic space data service, and defining calling parameters of all geographic space data service; thirdly, establishing geographic space data service configuration in a background configuration management system; fourthly, dynamically obtaining a configuration file by a mobile side through a service interface; fifthly, achieving a space data displaying and inquiring function by the mobile side. By means of the method, thedynamic configuration of all geographic space data integrated in the mobile client side can be realized, the application requirements for rapid displaying and inquiring on the mobile client side aremet, and the user experience of geographic space data application under the mobile side environment is greatly improved.

Description

technical field [0001] The invention relates to an integration technology of geospatial data services on a mobile client, in particular to a method for quickly displaying and querying multi-source heterogeneous geospatial data services on a mobile client. Background technique [0002] The integration of geospatial data services on mobile clients has the following characteristics: [0003] 1) Various data formats: the storage and access methods of geospatial data are not the same. There are online services and offline data packages. Online services include services that meet OGC standards, and there are also private services for each GIS platform. Offline data packages There are vector data packages and there are slice data packages. [0004] 2) Large amount of data: Whether it is basic surveying and mapping data or thematic spatial data, the amount of data is relatively huge, especially for large-scale data, there are a large number of complex line and surface data, and the...

[0005] 3) Slow display speed: Spatial data often requires several layers to be superimposed, especially when displaying all spatial data in the full range, fast graphical display of spatial data requires strong computing power on the mobile terminal

[0006] In view of the above technical problems, the existing mainstream solutions often use a single geographic information service release platform, such as using the ArcGIS Server platform to realize the display and query of geospatial data on the mobile terminal based on the MapService service, but the spatial data display It is often difficult to balance both performance and query performance, and the actual application effect is not ideal
