Go to the desired location in the map, set two markers by clicking the map to define a rectangle (or enter coordinates manually). Click the button [get data]. Optionally you can change the number of elevation samples you want in each direction, the more the better (max 400). You can also change the number of contours or set custom contour values. You can save some data in cookies, however there is a limit. Use the manual saving text areas below alternatively.

Please note, as for now, the drawing below is square and you may want to stretch it to cover the actual area in a map.
