Use of WFS in MapServer
6. Use of WFS in MapServer#
We can easily get the map in the specified area from the WMS server, but we can only get the rendered map. Sometimes we want to get data such as the geographical coordinates and attributes of a specified layer, and further, when we need to modify the data of the data source, WMS can not meet the needs.
However, you can also send data from the Web service to the client upon request. As long as the server and the client follow the same specification, the data can be in any format. In order to standardize the process of sending vector data through Web services, OGC provides us with another standard Web Feature Service (WFS) to meet the above requirements.
Next, we will introduce the release, access and application of WFS and its services.
