What is Web Map Service (WMS)?

The OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application.” ~ OGC

How does WMS work in practice?

To grant you ability to provide WMS as viewing service, we implement an open source solution – GeoServer.

GeoServer is a Java-based server that allows users to view and edit geospatial data. Using open standards set forth by the Open Geospatial Consortium (OGC), GeoServer allows for great flexibility in map creation and data sharing.” ~ GeoServer

How to provide WMS in

To provide Web Map Service as viewing service, first you need to edit the project which you want to generate WMS for.
After you’ve entered your project you need to click on the cog icon  at the Services tab.

A window will pop up asking you to select layers which you want to provide WMS for. After you’ve selected desired layers, press „Publish” and they will be ready to be served through Web Map Service as viewing service.

You will now be able to notice, that in „Services” tab appeared two services with one being the WMS.

Upon clicking the button, you’ll be presented with a service address that is ready to be used. For example:

publish service window
publish services pop up

How to use WMS?

You’ve clicked on the link and got something that looks like an error or some programming gibberish? Don’t fret, it’s likely that everything is working properly.
Network services’ addresses work differently from what you would expect from an ordinary Internet link. Without a dedicated interface that can process network services such as WMS, getting the data you need will require knowledge and skill to create quaries to databases. If you want to go about in-depth about creating requests to WMS servers manually, click here.

But don’t worry! If you’re not skilled in working with databases you’re not doomed.
There are several examples of software that allow you to take advantage of Web Map Services using user-friendly interfaces such as, QGIS, ArcMap or GeoNetwork.

Let’s begin with shall we?

To add layers through WMS service to your project, head to the „upload layer” option. Then you’ll want to move to „WMS” tab where you can paste WMS address into „WMS link” area. After pressing the download button will establish a connection between application and provider’s servers. This will result in a list of layers that you can select and temporarly add to the project.
