Hi,<br><br>I have mapserver, maplab 2.2.1 and the rosa applet installed. I have a mapfile, which has a layer, which i can show in the rosa applet. <br><br>My question is, is it correct to calculate the real coordinates from the input_coordinates (which is the pixed coordinates if you click) by simply proportioning them according to the extent coordinates?<br><br>I mean,<br><br>Real X Coordinate = (Difference in Real Extent Coordinates)/(Width of Rosa in pixel)*(clicked pixel X- coordinate) + Minx Real extent Coordinate<br><br>(Same for the Real Y Coordinate.)<br><br>Or is there another way to do this ? I read of maplat and maplon attributes but I don't know how to apply this within my package..<br><br>I hope I could clarify what I mean. Thank you in Advance.<br><br>Baris<br><br><p>
