Sometimes we have to convince our clients that it pays to invest in updating a dataset. For example, 10,000 new apartments, including workplaces, schools, kindergartens and supermarkets, will be built over the next few years in the Vienna urban development area Nordbahnhofgelände. An example that shows that your analyses will only produce accurate results if the data is updated at reasonable intervals. We place great importance on quality when selecting our partners. This includes the regular updating of their data.
