Welcome

These web pages aren't really current any more. My current activities revolve around the Geofabrik.

Welcome to my web site. My name is Jochen Topf and I have been working as an independent freelance consultant since 1995. I am available for small and large projects, everything from giving a one-hour talk to multi-month development projects. Contact me if you are interested. I am looking forward to working with you.

On these pages you'll find information about my work, the focus of this work, and a list of some of my clients. A lineup of work and work-related projects and a list of publications is also available. More about some of my projects and what else I am doing can be found on my personal web site.
