geoserver

We used to send parameters to our WMS geoserver SQLViews by the viewparams field. But WMTS doesn't have this field

Geoserver offers to use parametrized SQL views. Parameters are put in a viewparams field and it receives them as parameters for the SQL request.

However, we discovered that tiled WMS (WMTS) doesn't have that viewparams field.
How can we send our parameters ?

Solution

  • I discovered that WMTS layers have for target to be cached by tools/components like GeoWebCache, while WMS ones are always ran by the geoserver.

    A WMTS layer can be called in WMS mode, and then :

    • If you need to use a parameter, put it in the SQL view, and call the layer with a WMS request, with the viewparams parameter,

    • If you do not need to use a parameter, call it through WMTS and then futher calls might benefits from the contents being recovered from cache.
