How do I plot latitude/longitude coordinates on the screen?


I am trying to figure out how to plot WGS84 latitude/longitude points on a bitmap but cannot figure out the math required to turn lat/lon points into coordinates that would be plottable. Could anyone give me some pointers or examples on how to do this?

thanks

Colin


Solution

  • You might have a look at the Mercator Projection Demo, with Delphi source code:
