[mapserver-users] what is the map scale value for an image with 5m pixel

[jk]

Hi,

I have a layer of images each is made of pixel size 5 meter. I'm wondering
what is the minscale/maxscale value I should put in to map server map file? 

Also, I have a orginfo output that say this pixel size value of Pixel Size =
(0.019400225288651,-0.019400225288651) ,  what is the scale value for this
map?

Please pardon me for the almost-silly questions.

JK
