Here are some world maps I made using this shoreline data over the last 3 weekends. The original data is in the public domain, and so in turn the images are completely free to use for any purpose.
I haven’t yet projected the data (eg. mercator), so don’t consider the sizes accurate. All maps were made in javascript using processing-js. The data is loaded directly from a large json data file and is usable as static content without any server side support.
The code used here is available on github and is totally free to use for any purpose.
My weekend project was to build a real time zoom into Manhattan’s tweets. The zoom starts at a large enough radius to see DC, but as you zoom in you can also see Phillie and eventually NYC. Check it out running in your browser here. If you can’t run it then see the video below for some of my stop-motion draft versions which are not as finessed:
