[mapserver-users] World File's

2012-06-19 Thread Jeff Lake

Heres a trick question for anybody that wants to tackle it ..

I have ...
Lower Left Lat/Long
Upper Right Lat/Long
Center Lat/Long
and the LCC Projection Angles

I am attempting to create a World File for each of these maps (8 in total)
all the calculations I have found require Upper Left and Lower Right
well you can't just use the pairings I have as it will change being 
projected and not grid


anybody got any idea's ???

Maybe convert to planar coordinates, calculate the other corners based on 
distance and then convert back to LCC?
