<p>I am facing a problem with Map server and i believe it is about a mistake i am doing in Map File. i will be thankful if you help me to sort that error out.</p>
<p>I have made a new layer which contains a lot of POI. the problem is that whenever i zoom in more than 22.2 with units in meter that layer becomes disappeard. i want to know how may i keep that layer visible for next zoom ins ?!
