This study shows, how to linked GPS, RS, LiDAR and GIS mapping facilities of urban distribute network, positioning of the water projects and the storage water reservoirs for the water supply systems, with consideration of the earth’s surface properties, land-use change and ownership. Moreover, the use of the Global Positioning System (GPS) with Remote Sensing imagery in surveying, modernizing and developing Baghdad city complex water supply network is discussed. The data of land-use and current water supply system was generated using the Quick Bird Satellite Image (0.6m resolution data, 2015) with a map of the city of Baghdad at scale 1:25000 and field update survey. The necessary water supply system maps and data were collected from the Mayoralty of Baghdad (MoB). The Digital Elevation Model (DEM) and the contour map were generated from the LiDAR point cloud. All these techniques and geospatial data were mapped and analyzed in ArcGIS 10.2.2 software. The outputs of the study were the water distribution network with the position of projects, reservoirs, pipelines, etc. The interpretation of the geospatial database with analytical tools allowed the water distribution network to be planned more economically and effectively.
