Free Maps & Geodata
Geodaten in öffentlicher und privater Hand werden als wertvoller Asset betrachtet, besonders im Hinblick auf das erwartete Geschäft mit location-based Services. In den USA sind dagegen öffentlich generierte Informationen frei zugänglich (z.B. http://maps.google.com). Eine Alternative sind per GPS-Mapping kooperativ und frei erstellte Landkarten und Stadtplänen (z.B. http://www.bbbike.de).
Problem des Kartenmaterials: z.B. Xpedia-Karten sind für private Zwecke relativ bezahlbar zu lizenzieren, aber nicht fürs Web oder für kommerzielle Anwendungen Alle wittern das Geschäft mit location-based Services, XML.

This project is aimed at collecting GPS-logs from from people involved and giving the database away to everyone who is interested for free.

In the UK, 5.5 billion € are put into mapping each year. Since 2000, the UK has become less data secretive. PSI Directive = Public Sector Information, EU data reuse provision since 1. July 2005 (UK: SII 1515 2005) In UK, state data is under crown copyright, health rules, ... all different conditions. Freedom of Information is essential for getting ps data. In place for environmental data since the 1990s. Didn‘t work. 15 mio public employees handle it, all interprete the rules in a different way. Old data is thrown away. A map from 20 years ago? No, don‘t have it. FOI -> yes, but difficult to actually get it. Ordinance data is under crown copyright. Is it covered by database rights? Not known. Pub. servants might not give it out for fear that it might be illegal. PSI Directive: data must be given free, for non-commercial use, it should be free. Or for marginal cost. If they want more, they have to prove cost. Is strong on transparency. They have to build portals for metadata. public sector information is designed for employees, not for reuse by citizens. But: driven by user needs. National community broadband infrastructure, mapped local broadband, mostly WiFi‘ers
Google Earth gets attention TUESDAY, DECEMBER 20, 2005 http://www.iht.com/articles/2005/12/15/business/image.php NEW YORK When Google introduced Google Earth, free software that marries satellite and aerial images with mapping abilities, the company emphasized its usefulness as a teaching and navigation tool, while advertising the pure entertainment value of flying over high- resolution images of the Eiffel Tower, Big Ben and the Pyramids. But since its debut in June, Google Earth has received attention of an unexpected sort. Officials of several nations have expressed alarm over its detailed display of government buildings, military installations and other sensitive sites within their borders. India, whose laws sharply restrict satellite and aerial photography, has been particularly outspoken. "It could severely compromise a country's security," V.S. Ramamurthy, secretary of the Indian Department of Science and Technology
