Abstract

The invention provides a method, a device and a system for processing multi-source map data. The method comprises the following steps of: selecting a data reading interface corresponding to a geographic information data source interface format from a multi-source map data processing system and reading geographic information data from the geographic information data source according to the information reading interface; carrying out layering operation on the geographic information data according to preset image layer classification to obtain geographic information layered data; unifying a coordinate system; and loading and presenting the geographic information layered data on a map in an image layer form. The business operation request of a user is detected by the layer port and is transmitted to the dispatching center, and the dispatching center dispatches corresponding layer port of the layer to perform the business operation. The scheme can synthesize various types of data provided by all manufacturers, display the data in an optimal way and solve the problem of unshared different data source data on an application platform due to different formats and interfaces of the geographic information data provided by different manufacturers.

Description

technical field [0001] The invention relates to the technical field of geographic information systems, in particular to a multi-source map data processing method, device and system. Background technique [0002] Geographic Information System (GIS, Geographic Information Systems) is a high-tech technology that integrates computer graphics and databases to store and process spatial information. It organically combines geographic location and related attributes, and integrates spatial information and Its attribute information is accurate and true, and it is output to users with pictures and texts, which meets the requirements of urban and rural construction, enterprise management, and residents' life for spatial information. With the help of its unique spatial analysis function and visual expression function, various auxiliary decision-making is carried out. At present, GIS is stepping out of the traditional fields such as surveying and mapping, drawing, resources and environme...
