Hi Marc,<br><br>if you are using UMN MapServer, you always have an opportunity to change the parameters of a class in a mapfile via URL. The URL should look like this:<br><a href="http://yourhostname/cgi-bin/mapserv.exe?map=yourmapfilepath&REQUEST=GetFeatureInfo&...&layer_youlayername_class_yourclassname_tolerance=5">
http://yourhostname/cgi-bin/mapserv.exe?map=yourmapfilepath&REQUEST=GetFeatureInfo&...&layer_youlayername_class_yourclassname_tolerance=5</a><br>whereby "yourlayername" and "yourclassname" stay for the layer name and the class representing the layer as defined in the mapfile.
<br><br>If you are using another GIS server as for instance GeoServer, that doesn't support mapfiles and custom classes, you should look for a workaround. I would suggest to use the GetFeature request (WFS service) instead of GetFeatureInfo (WMS), because in this case you don't have to explicitly define the map position (parameters X and Y). Instead of this you only type a BBOX (minimum and maximum values for latitude and longitude) in your URL, which defines the area of interest, and the response you get from the server will contain all the features in this box. The BBOX could easily be computed via javascript.
<br><br>If none of those suggestions is helpful, please describe your configuration and your actions in detail so I could exactly understand what you are doing and what you're trying to achieve.<br><br>Regards,<br>Dmitri

Hi Dmitri,<br>
<br>
I tried to make a manual query with this parameter without success. <br>
<br>
Usecase (this is part of the query referring to the place where the
click is made): <br>
SUCCESS : X=235&Y=503<br>
FAILURE : X=235&Y=504<br>
FAILURE : X=235&Y=504&TOLERANCE=5<br>
<br>
So the TOLERANCE parameter doesn't affect the query...<br>
<br>
I tried to search internet for any wms parameter refering to TOLERANCE
but could'nt get any information about it. If you can provide any clue
about how to use it, or any documentation referring to it please help.<br>
<br>
<br>
Thank you :)<br><span class="sg">

<br>
in a WMS/WFS service request the attribute you are looking for is
called TOLERANCE. I think this should do it when set as a parameter in
getFullRequestString function (see user recipies: <a href="http://trac.openlayers.org/wiki/GetFeatureInfo" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://trac.openlayers.org/wiki/GetFeatureInfo</a>).<br>
<br>
Hopefully it helps you out.<br>
<br>
Cheers,<br>

all,<br>
<br>
I search for an attribute to set to make it easier to click on points
to
<br>
get some info about them.<br>
I tried some things like RADIUS or REDIUS (saw that on a page on<br>
internet) but nothing works.<br>
<br>
I just want it to be easier to click on the point if it's possible, a<br>
couple of pixels more.
<br>
<br>
<br>
Thank in advance,<br>
<br>
Marc<br>
