ogc-client

A javascript library for interacting with OGC-compliant services

ogc-client is a pure Javascript library which implements several OGC standards and will help you interact with them in a user-friendly and consistent way.

The following standards are partially implemented:

• WMS - Web Map Service
• WFS - Web Feature Service

Why no WMTS support? Because openlayers has a incredibly thorough and well-tested WMTS capabilities parser and you should just use it. Reimplementing it in ogc-client currently does not bring any significant value.

Why use it?

• ogc-client will abstract the service version so you don't have to worry about it
• ogc-client will handle XML so you only have to deal with native Javascript objects
• ogc-client will hide the complexity of OGC standards behind straightforward APIs
• ogc-client will run heavy tasks in a worker to avoid blocking the main thread
• ogc-client will keep a persistent cache of operations to minimize requests and processing
• ogc-client will handle errors in a graceful way and extract relevant messages for you
• ogc-client will tell you if a service is not usable for CORS-related issues

Instructions

To install ogc-client, run:

$ npm install --save @camptocamp/ogc-client

Demo

The demo app is located in the demo folder. To start it locally, clone the repository and run the following commands:

$ cd demo
$ npm install
$ npm run serve

The app is based on Vue.js 2 and will showcase most features implemented in the library. You will need to supply it with valid OGC service urls.
