The methodololgy applies Geographic Information Systems (GIS) tools to a polynomial model that relates d18O to latitude and elevation. First steps in the development of this methodology have been made and tested in a limited part of Spain, the province of Burgos, where the resulting map of d18O in precipitation has been compared with isotope data from river water and ground-waterspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Stable isotopesPrecipitationGIS toolsHydrogeologyjournal articleopen access
