Hi,

 

Just thinking, but is there such a thing like scale with WFS actually? Does Mapserver know at all at which scale the client is going to show the vectors? Is there a way do define minimum and maximun bounding boxes instead?

Aihe: [UMN_MAPSERVER-USERS] WFS - Playing with scales

Hi,

 

I configured a mapfile for a WFS service.

The MINSCALE and MAXSCALE dont seem to be working properly since data is displayed at any scale ...

I did the same thing for a WMS service (another mapfile) and it works fine.

Any idea why it doesn't work with WFS ?

 

Other question:

Is it true to say that when I connect to a WFS service and I display a particular layer, all the data from that layer is loaded initially. This causes the first display to be slower but any modification to my view afterwards (zoom area, zoom out, pan, etc ...) is (almost) instantly since data is all on the client side ...
