Until 2015 the Norwegian cadastre data was a closed data source, practically unavailable for commercialization. Authorative thematic data sets are widely produced by federal governments which, by law, are open and freely available. Norkart Webatlas strategically formed business cases and aimed at commercializing and generating a foundation for jobs based on open spatial data. Two years into this race we will share our experiences: pitfalls and successes which have paved the roads for a sound business providing solid jobs for tens of people. Changing the way clients think about "open", pushing clients to develop under open licenses and internally adopt a "open" mindset are some of the challenges we faced. In this talk we will share how we have done this and hopefully inspire others to generate solid jobs based on open data and open source software.
