Introduction Although data, models, tools and information are the corner stones of hydraulic engineering Introduction Although data, models, tools and information are the corner stones of hydraulic engineering projects: • Data quality, availability and accessibility for analysis is substandard • Models and tools used and developed by specialists are insufficiently documented and often lack version control • Developments to remedy the two above points are often hampered by the existence of (artificial) project boundaries • Working like this is grossly inefficient We can do much better!!

Introduction Surely you recognize the following emotions? • ohh , I used the wrong Introduction Surely you recognize the following emotions? • ohh , I used the wrong version • ahh, where is the last version • hmm, where was this measured • oops, I forgot to include the timezone • wow, you can actually show that in Google. Earth? • aarghh, the guy who measured it left? • sigh, surely someone must have solved this problem before me! Open. Earth was started as a bottom up initiative by project engineers to break this apparent endless string of disappointment and frustration by introducing an open and project superseding approach. So how does it work?

1. PHILOSOPHY • Non-zero sum game: collaboration most efficient for everybody (more pie) • 1. PHILOSOPHY • Non-zero sum game: collaboration most efficient for everybody (more pie) • Tit-for-tat is what people start using for cooperation • People stop collaborating after 1 st bad experience • Tiny % of free riders gradually destroys collaboration • Tit-for-tat+1 approach would maintain collaboration • Stop collaboration only after 2 nd bad experience. • Noise in system: delays + misunderstandings + force majeure • also gradually cooperativeness erodes. • Tit-for-tat+many maintains collaboration • Mutual trust • Positive attitude • Cooperative atmosphere • Only 1 needed • OET = car starter
