Problem in generating contour

Hi,
I have a raster image which cover half land and rest is water.
Load that tile into global mapper the generate contour.
When I say generate contour at 20meter on the tile then it will show an error
(No Specified contour found on the specified area.)
I think there is no contour at the difference of 20meter in water area.
So what i have to do for creating contour at 20 meter???

What are the heights of your land and water areas? If you generate contours at some interval, say 20m, you will get contours wherever the elevation crosses from below a multiple of that value to something above, so if your water is at zero and there is nothing below that, there won't be a 0 contour. What you can do is slightly shift your terrain values, say by -0.01 meters, then generate the contours to get what you want. You can do that on the Adjust Elevations tab of the Options dialog for a layer.
Let me know if I can be of further assistance.
Thanks,
Mike
