[mapserver-users] Point between 2 tiles disappearing

[Geo-6]

Hello,

 

I forgot to say that Leaflet access to MapServer via WMS.

 

Here is a copy of the MAP file :

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.
