So, I have a geoserver layer with point markers (POI) in several category such as ATMs, churches, government buildings, parks, etc. Is there a way to filter this layer via URL parameters so I don't have to define a new layer for each category? also, I am using openlayers-3 as the frontend interface.
To complete the question, I have a request URL like this:
where each of category is saved as
category in postgis
Now I want to filter based on category, for example I want to use filter to only show police stations
