I am a Geographer with some background in applying Geographic Information Systems (GIS) in the area of Land Mangement, Land-Use Planning, Land Registration and Nature/Wildlife Protection. Sometimes, e.g. talking to my beloved Grandmother or to kids, who still have a real sense of the world, I might just say: “I am making maps. Maps with Computers”. Nowadays, I am mostly teaching Geoinformatics to undergraduate students.

Originally from Frankfurt (Germany), I am currently based in Chiang Mai, Thailand.

In a judgment of 12 May 1998, Hamburg Regional Court (Landgericht) ruled that publishing Internet links may make a website owner liable for the content of the linked third-party web pages. The Court held that only by explicitly dissociating his website from the linked site`s content can the owner avoid such liability. Sylla-Consult has placed links to other Internet sites on its web pages. The following disclaimer therefore applies to all these links: Sylla-Consult states explicitly that it has no influence over the design or contents of the linked sites. The Institute hereby expressly dissociates itself from the entire content of all pages and sub-pages linked from its homepage; inclusion of a link to a third-party website does not imply any endorsement of its content. This disclaimer applies to all links featured on the Sylla-Consult website, as well as to the content of all pages to which the visible banners, buttons and links lead.
