Abstract

PREPARATION OF SOURCE DATA IN GIS PROGRAMS TO CALCULATE THE REPRESENTATIVE INDEX Ru ON THE EXAMPLE OF GROUNDWATER BODY NO. 37Abstract. The Water Framework Directive requires Member States to regularly monitor and protect the quality and quantity of groundwater. Assessment of spatial representativity within each groundwater body (GWB) is also recommended and the representativity index Ru has been proposed. For Ru calculation, GWstat software is suggested (WFD-GW, 2001). Due to difficulties in preparing raw data in the GWstat software, the author used ArcGis and IDRISI programs. The ArcGis was used to digitize the border of GWB 37 and location of boreholes in GWB 37 from the Polish Hydrogeological Survey GIS server (e-PSH). The IDRISI program was used to prepare the matrix of GWB. Initial estimation of Ru calculated in the GWstat is 57%.
