SFD Graphic Generator

About the SFD Graphic Generator

Use this tool to produce an SFD Graphic in just three steps.

Input the data relevant to your city (or urban area) and, with a couple of clicks, the tool draws an SFD Graphic that you can download for use in reports and publications.

The SFD Promotion Initiative developed the tool and if you have any questions please contact the SFD Helpdesk who will be happy to help.
