[Projection problem] - simple translation

[Selim Hernandez]

Hello,

I think my problem is simple but since I don't understand how the
projection system work, it seems confusing to me.

I have a map file with 2 layers that have 2 types of coordinates.
In fact, the two types are nearly the same, but on one of them, 3000000 has
been addded to the Y coordinate.

For example : (from a mif file)
here are the 2 types of coordinates (with or without 3000000) for the same
2 points.

REGION 1                   REGION 1
6                          6
887807.365 3091440.265     887807.365 91440.265
887818.530 3091439.880     887818.530 91439.880
...                        ....

I don't succeed in displaying both at the same time. I think I have to add
a PROJECTION object in my layers on maybe in my map object but I don't
understand the way it works.

If anyone has any idea, it would be very helpful.

thank you
