Aplicação De Sig Em Mapas Geoelétricos Para Geraçao De Mapa Previsional De Água Subterrânea

The Geographical Information System (Gis) Provided A Substantial Progress In The Mapping Systems Through Computing Graphic Methods, And It Is Being Established Like An Important Tool In Several Areas Of The Knowledge. The Present Work Presents An Application Of Operations Offered By This System To A Group Of Two Maps Generated In A Geoecletric Investigation, Accomplished In The Nw Portion Of Mundaú River Basin, In The Municipality Of Itapipoca, State Of Ceará. The Geoelectric Maps Was Processed Using The Idrisiw Software, And Through Reclassification And Overlay Operations, Considering Restrictive Approaches Established From The Interpretation Of The Geoelectric Maps, It Was Defined A Zoning Of The Most Favorable Areas For Groundwater Exploitation.
