Extract xyz data from contour map
显示 更早的评论
My data is xy rings with z as a height. I create a contour map of the data. I need to be able to create xy data points with the z component having a value somewhere between the 2 contour lines. Then extract all of the xyz data. I have found a few programs to extract the data but it is only x,y data and it is basically the xy data that I originally started with.

You know the levels at which you drew the two contours. Let's say they are at 30 and 50. So now let's say you want all x,y coordinates at a level of 40, which would be in between the contour lines at 30 and 50. Just do
[y, x] = find(z == 40);

I don't know what you're asking. What data? You can use the line of code I gave you to get the x,y coordinates of any array, and the z values at every point on the contour will simply be the z value you asked for. So I have no idea what you're asking.
