is it possible to draw grd file using Mapserver

[Guillaume Sueur]

Merhaba Murat,

Frankly I'm not sure to understand what you want to draw as point and 
what as polygons, but anyway, this can probably help you...
What about using OpenLayers VectorLayer to render your points ? This 
way, you could directly use your text file and then have full control on 
the client side to render them properly, by small or large circles for 
example.
Have a look to 
http://www.openlayers.org/dev/examples/vector-features.html and 
http://www.openlayers.org/dev/examples/markersTextLayer.html to see some 
live demos. You can still use MapServer to generate your background layers.

Hope that helps,

Guillaume
