Presentation for the 6th Rural Water Supply Network Forum, Kampala, 2011 Abstract Free online information can be beneficial in the preparation, design and implementation of rural water projects. Free online sources of meteorological data (rainfall, evaporation), maps (topography, geology), aerial imagery and elevation data are presented together with examples of how this information has been used in rural water projects. This online information can never fully substitute field observations and measurements, but it can provide valuable additional information and make preparation, design and implementation of rural water projects more efficient and successful.
