The Plan4business project (2012-2014) has identified a gap in land use data availability, especially outside big cities, in suburban and rural areas. The Urban Atlas of the European Environmental Agency covers only cities above 100,000 inhabitants. So for example in the Czech Republic, only 13 cities are covered. For the rest, there is the Corine Land Cover, which can be used only for regional and national analysis.
The lack of land use data on local level led to an idea of combining data from various sources and of different levels of detail into a seamless map. This idea has been picked up by the SDI4Apps project and turned into a pilot application (Pilot IV: Open Land Use Map through Volunteered Geographic Information). The innovative aspect of the pilot is not only in the methodology of combining data into a seamless database, but also in using crowdsourcing for data collection and update. An important aspect is that data are available as open data.
The methodology is simple:
The aim is to cover the entire Europe and then extend it to a global dataset. The first country that is now completed is the Czech Republic where the following open data sources were used:
The steps undertaken for combining the data are shown in the following figure.
