[mapserver-users] Point between 2 tiles disappearing

[Geo-6]

Hi,

 

I use Leaflet (http://leafletjs.com/) and MapServer with WMS.

Example : http://localhost/wms?map=mymap.map
<http://localhost/wms?map=mymap.map&SERVICE=WMS&REQUEST=GetMap&VERSION=1.1.1
&LAYERS=mylayer&STYLES=&FORMAT=image%2Fpng&TRANSPARENT=true&HEIGHT=256&WIDTH
=256&NOWRAP=true&SRS=EPSG%3A31370&BBOX=11999.999729989533,-139999.9996253261
3,139999.99967443026,-11999.999682342634>
&SERVICE=WMS&REQUEST=GetMap&VERSION=1.1.1&LAYERS=mylayer&STYLES=&FORMAT=imag
e%2Fpng&TRANSPARENT=true&HEIGHT=256&WIDTH=256&NOWRAP=true&SRS=EPSG%3A31370&B
BOX=11999.999729989533,-139999.99962532613,139999.99967443026,-11999.9996823
42634

 

I do not use MapCache.

 

Thanks !

MapServer expands the search extent slightly based on feature definitions
(e.g. marker size, etc...) so that partial features are captured and
rendered. That should take care of a case like this. What are you using to
do the tiling (i.e. mapcache, tilecache, mode=tile)?

Hi everyone,

 

I use MS4W (see below for more information on my version of MapServer) with
Leaflet.

The projection system I use is EPSG:31370 (see below for proj4 definition).

 

Sometimes, at certain zoom level, when a point is between 2 tiles, the point
is not shown.

Here are some screenshots :

 

Resolution = 10

 

 

Resolution = 5

 

 

Resolution = 2

 

 

Resolution = 1

 

 

You can see at resolution = 1 that the symbol is “cut”.

 

How can I fix this ?

 

Thanks a lot for your help and sorry for my English.
