Embodiment Construction

[0041] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0042] Such as figure 1 As shown, the embodiment of the present invention provides a method for publishing a vector map service in DWG format, comprising the following steps:

[0043]Step 100, receiving a map access request sent by the client through the Internet, the request includes parameters such as the layer, spatial range, and output format of the DWG data to be accessed.

[0044] Step 200, verify the data access authority of the client; if the authority is approved, analyze the map access request sent by the client, otherwise return a prompt message of denial of access.

[0045] Step 300, analyzing the map access request sent by the client, including analyzing the map parameters requested by the client, the ...

Abstract

The present invention relates to a method and device for publishing a vector map service in DWG format. The method first receives and analyzes a map access request sent by a client, and the request includes DWG data parameters to be accessed; read the DWG data parameters according to the map access request. Get the DWG data, including the complete DWG file and the symbol parameters of the layer elements; encapsulate the read DWG data into a vector map service that conforms to the WMS or WFS standard of OGC, or the MapServer standard of ARCGIS; The service is returned to the client through the communication interface. This method can directly publish DWG data as a vector map service in one step, which saves the process of converting DWG format data into GIS format and then using the GIS sharing and publishing method to publish vector maps, avoiding the symbols caused by data format conversion Missing or vector seam problems.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method and device for publishing vector map services in DWG format. Background technique [0002] The emergence of Web Geographic Information System (WebGIS) has changed the publishing and sharing methods of geographic information systems. It is an important change in the application of geographic information data in recent years to provide users with spatial data browsing, query and analysis functions by using web publishing spatial services. . Vector topographic maps with DWG as the main data format are an important part of urban survey results and play an important role in urban planning, construction, and management. How to quickly publish these DWG format data into networked map services has become a Urgent demand, the sharing and release of DWG vector topographic maps is of great significance for improving the product categories of online geographic inform...
