Embodiment Construction

[0020] In order to solve the problem in the prior art that data is easily lost due to the use of storage media to interact between different GIS software platforms, the embodiments of the present invention provide a method and device for releasing spatial data.

[0021] like figure 1 As shown, the method for publishing spatial data provided by the embodiment of the present invention is applied to a geographic information system, including:

[0022] Step 101, obtaining spatial data;

[0023] Step 102, converting the spatial data into a unified expression form;

[0024] Step 103, publish the spatial data with unified expression on the Internet through the vector markup language.

[0025] The method for publishing spatial data provided by the embodiment of the present invention converts the spatial data into a unified expression form, and publishes the spatial data with the unified expression form on the Internet through vector markup language, so that the same expression form ...

Abstract

The invention discloses a method and a device for publishing spatial data, which relate to the field of geographic information systems and aim to solve the problem that the data is easy to lose due to interaction performed by adopting a storage medium among different GIS software platforms. The technical scheme provided by the invention comprises the following steps: acquiring the spatial data; converting the spatial data into a uniform form of expression; and publishing the spatial data of the uniform form of expression on the Internet with a vector markup language. The technical scheme provided by the embodiment of the invention is applied to the geographic information system and a geographic information system software platform.

Description

technical field [0001] The invention relates to the field of geographic information systems, in particular to a method and device for distributing spatial data. Background technique [0002] GIS (Geography Information System, GIS) is a decision support system, the information it stores and processes is geocoded, and the geographic location and the attribute information related to the location become an important part of information retrieval. In GIS, the real world is expressed as a series of geographic elements and geographic phenomena, and these geographic features are at least composed of spatial location reference information and non-location information. The data organization, data storage, information retrieval, and information processing of spatial location information are different from non-location information, and the general information data storage and processing methods are not suitable for GIS systems. [0003] At the end of the 20th century, professional GIS ...
