Problems solved by technology

[0008] However, although WMS is very efficient and easy to access, the price is that it needs to perform time-consuming and laborious map slicing in advance. Once the layer elements change, they need to be re-sliced ​​and released. Therefor

Abstract

The invention belongs to the technical field of electronic maps, and particularly relates to a method and a device for establishing and operating an electronic map aggregated layer. The method for establishing the electronic map aggregated layer comprises the following steps: S1, selecting a map element layer as a meta layer for establishing the aggregated layer; S2, extracting out the meta layer from a spatial database, performing display configuration, establishing metadata, and building the aggregated layer; S3, registering the aggregated layer in a layer table. A user can specifically select map element layers to form the aggregated layer according to different application situations and individual demands. The map elements in the aggregated layer maintain storage modes and display effects of the map elements in the meta layer before combination, storage and display of different elements inside are not affected when the operation of aggregating layers is implemented, and in external feeling, all map elements inside different meta layers seem like an independent layer.

Description

technical field [0001] The invention belongs to the technical field of electronic maps, and in particular relates to a method and device for constructing and operating an aggregation layer of an electronic map. Background technique [0002] The electronic map is the use of computer technology to generalize the real three-dimensional world to the expression of the two-dimensional plane space. The map is stored and consulted digitally, and the real space where people live is expressed through various map elements. As the basic unit of electronic map management, layer Figure 1 These map elements are generally stored, managed, displayed and analyzed in the form of layers. [0003] For users of specific business applications, the mode of using maps is usually base map + background thematic layer + business thematic layer. The former two can include multiple layers, exist as a background, and only perform read operations, while business thematic layers require read and write ope...
