Re: projection

Hi,

I have ascii file containing latitude and longitude in decimal degrees
for a coast line. I just want to plot those coordinates as a mercator
projection.
Can I read a file of coordinates? Is it possible to do this kind of
plotting using openMap? I am not using any shpae file or image file, I
have only text file of lat/lon coordinates.
Thanks

Chhaya
