Insights to how Danish municipalities through "OS2 – Public Digitalisation Network" work together and share results. OS2 is: Openness – transparency is key in an open community. Collaboration – we are better and stronger if we unite. Sharing – knowledge and good solutions should not be proprietorial. Digital development – we want to be frontrunners where relevant. Open source licenses – prevents vendor lock-in. I will explain why open source create value for both the municipalities (local government, public sector) as for the vendors. And I will explain how we take action and do it in practice. OS2 = OS and the 2 as the exponent. The meaning is that OS is short for both Open Source and Offentligt Samarbejde (Public collaboration). ___ The Agency for Data Supply and Efficiency (Styrelsen for Dataforsyning og Effektivisering, or in short: SDFE) is the National Mapping Authority of Denmark. Today that doesn’t just mean producing maps, it also entails producing good basic geodata that others can use in their products. In certain parts of our data production we rely heavily on free and open source geospatial software. Most of which is maintained within the OSGeo foundation. During the last few years we have gone from being strictly users of the software to also being contributors to select projects. Most notably PROJ.4 which is a fundamental piece of geospatial infrastructure across the internet. PROJ.4 is the de-facto standard application for transforming between different geographical coordinate systems. Besides our involvement in existing projects we have also released various pieces of software under an open source license. Examples are the production system for the Danish Elevation Model and a framework for simulating flash flooding scenarios. Some has been produced in-house and some has been developed by subcontractors with the intent of releasing the software as open source projects. This talk will present examples of the software which SDFE has created or contributed to and the experiences we’ve had with it in an open source context.
