SURSE DE DATE ŞI FUNCŢII DE GEOPROCESARE UTILIZATE LA OBŢINEREA MODELULUI DIGITAL AL TERENULUI, PREMISE ÎN CUANTIFICAREA GIS A REŢELELOR HIDROGRAFICE DIN ZONA ALBA IULIA

Abstract

Information and functions sources of geoprocessing used to obtain digital terrain model, to quantify GIS hydrographical network in Alba Iulia area.
