DETERMINATION DEFECT SITES OF WATER NETWORK PROJECT USING GIS

Initially the methods of determination defects sites was done traditionally , but after the scientific development in GIS (geographic information system ) which used many applications , the process has become much better , in this research includes determination defect sites in the design of water network and how to processed it .The work was done with a high accuracy corrected satellite photo taken (Quick Bird ) with (0.6m ) resolution for Nasiriyah image 2005 , and in this research the work done by using the Geographic Information sysyem (GIS) program to processed it by Geometric Network tool in the arc catalog & through establishment of layers (shipefile ) for the water pipes of the study area and after drawing process is finished , the tool in the program (Geometric Network) determine defect site in the design water network then processed
