What is Web Feature Service (WFS)?

The Web Feature Service (WFS) represents a change in the way geographic information is created, modified and exchanged on the Internet. Rather than sharing geographic information at the file level using File Transfer Protocol (FTP), for example, the WFS offers direct fine-grained access to geographic information at the feature and feature property level.” ~ OGC

How does WFS work in practice?

To grant you ability to provide WFS as download 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 WFS in MapMaker.online?

To provide Web Feature Service as download service, it’s the same procedure as WMS. First you need to edit the project which you want to generate WFS 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 WFS for. After you’ve selected desired layers, press “Publish” and they will be ready to be served through Web Feature Service as download service.

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

Upon clicking the button, you’ll be presented with a service address that is ready to be used. For example: https://geomapmaker.online/geoserver/UniejowMwMpzp/wfs

How to use WFS?

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 WFS, 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 WFS 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 Feature Services using user-friendly interfaces such as MapMaker.online’s GeoNetwork, QGIS or ArcMap.
