Maps are the epitome of visual description, helping us see different perspectives or layers of information in (what should be!) a coherent and captivating image. Digital maps and data help us see inequality and investment opportunity, patterns of movement and pockets of danger or deprivation. As #MapLondon co-creator Rebecca Lee put it, can we share that insight more effectively to make better decisions about cities?

As part of #MapLondon‘s crowdsourcing drive – including input into conference workshops and projects continuing into 2020 – we invite fellow map geeks from London and around the world to create a commemorative poster: ideally the first of many!

The theme is ‘Digital Mapping for Better Cities’ and a panel of independent judges will be looking for strong expression of the theme; visual appeal; and legibility.
