Using web services
There are quite a few different types of web-based map service that can be loaded in QGIS. Each type of web service provides data; often, this is the same data in different ways. This recipe is about helping you figure out what type of web service you want to consume, and conversely what type of web service you may want to create for others to use.

WFS: This is Web Feature Service
WFS-T: This is Web Feature Service, Transactional
WCS: This is Web Coverage Service
WMS:...
