Instructions

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.

This service comes without any warranty whatsoever, including but not limited to functioning or correctness.

Resources: This service uses ArcGIS Map by Esri, the OpenStreetMap, Geocoding by Nominatim, Mapzen, Leaflet, jQuery and the CONREC contouring algorithm by Paul Bourke and Jason Davies.
