A METHODICAL APPROACH TO GIS-BASED HYDROGEOLOGIC MAPPING
Dirk Masuch Oesterreich*
ABSTRACT
This paper describes a methodical approach to hydrogeologic mapping and outlines principles of data
management using Geographic Information Systems. Digital hydrogeologic maps and their underlying data
base are well suited for water resources planning. The concept of the digital hydrogeologic map presented in
this article focuses on the occurrence of productive aquifers and visualizes them by an “x-ray view” in the
base map that outlines hydraulic conductivity at groundwater level. Additional hydrogeologic cross sections
reveal the vertival distribution of hydraulic conductivity as well as the thickness of productive strata and their
tectonic setting. Regional hydrogeology can be presented by at least three different layers of information that
can be supplied in separate sheets: hydrogeological base map, hydrogeological cross sections, groundwater
contour
