My problem is that I have a vector map of the world (metafile) in MERCATOR Projection. I want to put this map on the background of my project. How do I convert the point co-ordinate in the metafile to REAL longitudes and Latitude, automatically compensating for the Mercator projection of the MAP. ( I can easily read the vector file) My current system draws the grid at equal intervals of five degrees, but is equidistant, (just like squares, instead of rectangles in mercator). I draw the grid through a 'WORLD TRANSFORMATION' function which equates longitude and latitude to pixels on the screen. http://www.bae.uky.edu/~precag/modules/cpp.html http://www.ualberta.ca/~norris/navigation/Mercator.html High Level Discussion: http://www.cnr.colostate.edu/class_info/nr502/lg2/projection_descript... rcator.html Some source code in an unknown language: http://ferret.wrc.noaa.gov/Ferret/Mail_Archives/fu_96/msg00064.html >, My problem is that I have a vector map of the world (metafile) in >, MERCATOR Projection.

I am tracking the motion of the ships by Using sphrical trig0nometry and it is accurate. My problem is that I have a vector map of the world (metafile) in MERCATOR Projection. I want to put this map on the background of my project. How do I convert the point co-ordinate in the metafile to REAL longitudes and Latitude, automatically compensating for the Mercator projection of the MAP.
