Open source project-based internet map application development platform

Abstract

The invention discloses an open source project-based internet map application development platform, and relates to the technical fields of internet map services, applications and software research and development. According to the map application development platform, an object-oriented programming design thought is adopted; a GIS professional language is converted into a general internet software development language; 33 map basic classes and 25 spatial analysis interfaces are packaged in an open source-based Openlayers front-end map rendering engine; the packaged classes and interfaces of methods and the like are simple and easy to understand; OGC standard map data and map services are supported; and the platform has a front-end spatial analysis function. The problems of high learning cost, incapability of flexibly accessing standard map services and map data, and the like when non GIS professional development personnel develop internet map applications are solved.

Description

technical field [0001] The invention relates to the technical field of Internet map service, application, and software research and development, in particular to an Internet map application development platform based on an open source project. Background technique [0002] With the rapid development of the Internet, WebGIS came into being, and electronic maps have become an indispensable part of people's lives. Using electronic maps for navigation and positioning, visually displaying various data on maps, and using map data analysis to assist decision-making are the most demanding requirements in map application development. [0003] At present, various map software service vendors have launched their own map development APIs one after another. Internet map application development is mainly based on the WebGIS application development API or SDK of major geographic information software service vendors, but its technical system is complex and non-open source. For non-GIS profe...

AI Technical Summary

Problems solved by technology

[0003] At present, various map software service vendors have launched their own map development APIs one after another. Internet map application development is mainly based on the WebGIS application development API or SDK of major geographic information software service vendors, but its technical system is complex and non-open source. For non-GIS professionals For R&D personnel, it is difficult to learn and the development cost is high, and the spatial analysis function needs to cooperate with expensive background software

Although there are Internet map development SDKs such as Baidu and Gaode in the industry, they have problems such as non-open source, difficult debugging, inability to connect to standard data, and lack of spatial analysis functions.
