I need to create point sample stations on two contour lines (-10m and -20m). What I'm intending to do is, put markers (circle with stroke) on the contour lines, with equal distance from one point to another. I'm also willing to add a specific amount of station (30) for a specific amount of area in the map.
Although I have been able to make contour of both elevation mentioned, I don't know how to plot the sample stations as markers on map. How can I do this? Or is there a better way of doing this?
