<div dir="ltr"><div>With symbols MapServer typically handles this situation by adjusting the extent used to select features based on the largest symbol size - so features just off the edge of the map are still rendered partially. That said, based on your sample graphic it looks like you're setting the size of the circles dynamically using attribute binding? If so, MapServer wouldn't have access to those values ahead of time to adjust the selection extent. One idea might be to somehow add something in the red circle layer to force that computation, I'd have to see the layer definition to be sure but you could try adding a dummy class with a size value that represents the largest expected size. So:</div><div><br></div><div>LAYER</div><div> NAME 'red_circles'</div><div> ...</div><div> CLASS # this class is never drawn</div><div> EXPRESSION 'dummy'</div><div> STYLE SYMBOL 'cicle' SIZE 175 COLOR 0 0 0 END</div><div> END</div><div> CLASS</div><div> # your normal red circle class</div><div> END</div><div><br></div><div>Of course this forces the larger selection extent for all tiles but it could work and if the data isn't particularly big it wouldn't add too much overhead.</div><div><br></div><div>--Steve</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 26, 2020 at 12:49 PM TC Haddad <<a href="mailto:tchaddad@gmail.com">tchaddad@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><br></div><div>Can you configure Openlayers to not send tiled WMS requests to Mapserver?</div><div><br></div><div>If you still want to send tiled requests, you could try setting up MapCache to see if it improves the situation.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 26, 2020 at 1:09 AM Leehan <<a href="mailto:mathias.cunault@inrap.fr" target="_blank">mathias.cunault@inrap.fr</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I am not using qgis : It s an Openlayers + Mapserver application ; <br>
