Emporis
Emporis GmbH is a real estate data mining company with headquarters in Hamburg, Germany. The company collects and publishes data and photographs of buildings worldwide. Emporis offers a variety of information on its public database, Emporis.com. Emporis is frequently cited by various media sources as an authority on building data. Emporis previously focused exclusively on high-rise buildings and skyscrapers, which it defines as buildings "between 35 and 100 metres" tall and "at least 100 metres tall", respectively. Emporis uses the point where the building touches the ground to determine height. Today, the database has expanded to include low -rise buildings and other structures. It uses a point system to rank skylines. History. Michael Wutzke started a website about skyscrapers in Frankfurt in 1996. In 2000 he started skyscrapers.com, which was folded into Emporis in 2003.
