Quote from: "jurajs"you can define the contourline steps in phyghtmap easily... and for amount the meters you want to.I've never managed to make the maps myself, I've tried several times. :/
but ! you have to have in mind also that source elevation data is not continuos, therefore it does not make any sense to use lower values than 10 meters. I personally use 20 meter steps for contour lines for 2 reasons. 1) 20 or 25 steps are mostly used out there and its still detailed enough 2) to avoid enormous data generated by pyghtmap for contourlines in the map itself (comparing to 10m step)
