Chaining process – selecting features contained in a polygon


In the previous recipe, you started working with geoprocessing requests. Looking at the supported operations, you see that it is a very long one. There are several different operations you can perform on the data. Most of these operations are quite simple, while in a real-world use case, you often need more complex ones. So, how can you translate a real-world use case into a task that GeoServer is able to execute? The elegant and efficient answer is chaining processes.

WPS lets you use the result of an operation as an input to another operation. While this may seem very simple, it offers you an incredible flexibility and power. By using the built-in operations as building blocks, you can create very complex geoprocessing tasks. The WPS process builder will let us try out this powerful idea.

In this recipe, your target is to find all populated places located inside Switzerland.
