If you do this you have to calibrate the map by telling the software what L/L is represented by points selected on the chart. I don't think the original poster is likely to be doing this. I'm not aware of any calibration being necessary if you up load commercially produced charts. I believe the calibration data is part of the chart data. Len is keeping very quiet since his original posting. Has he found something embarrassing, and doesn't wish to tell us? |
