Open Data License/Attribution - Guideline
Community Guidline - Attribution
This page gives guidelines on what the OpenStreetMap community feels to be appropriate for attributing OpenStreetMap in different situations. Attribution is a basic requirement under the ODbL section 4.3.
THE CURRENT CONTENTS ARE DRAFT FOR FURTHER COMMUNITY COMMENT AND REFINEMENT.
1) Attribution in a TV news context. We welcome the use of a map/image/animation generated from OpenStreetMap data in a TV news story. Where possible, such image should display a brief attribution that OpenStreetMap data was used. The attribution does not need to remain in view when panning or zooming. The user may however supply credits on an associated website rather than within the program itself.
As well as attribution it is likley you will also have to comply with the requirements of section 4.6 of the ODbL.
