I'm digitizing a contour map to create a DEM, but there is a mine, and I'm a bit confused about it, I don't know how to digitize this.
There are different numbers (e.g. -62), that I think about the loss of the elevation, but there are more numbers that belongs to one line.
Any idea?

Here is a pic about the site:

Thanks in advance!
