To make the figures in a couple of recent important TfL reports more useful I have produced these interactive Google maps with images from the reports overlaid.
You can view the maps at the links below. When viewing a map you can quickly switch the overlay on or off by clicking on the ‘eye’ icon at the top left of the map.Download the TfL document (PDF 6MB)]

Method used to make these maps:
- Use Adobe Acrobat Reader or Pro to select a map in the TfL report as an image and save it as a JPG file
- Open file with GIMP
- change the image opacity to give the best transparency for each map (usually 30-50%)
- rotate 1 degree clockwise (to compensate for a systematic error in all the map images I’ve done so far)
- Save as a PNG file.
- Upload the PNG file to http://maps.camdencyclists.org.uk/tfl-strategic-cycling/ (or at another server)
- Use ScribbleMaps to create an overlaid map (instructions here)
- use the URL of the PNG file you uploaded as the overlay URL
- it’s worth devoting some time to scaling and repositioning the overlay to get decent registration. The only way I’ve discovered is to repeatedly adjust each corner until some easy-to-distinguish landmarks such as the Thames and Hackney Marshes are correctly overlaid.
- Use ‘Save Map’ on the ScribbleMaps menu to save and get a link to the overlaid map.
