Following BBC London’s use of open source mapping technology Crowdmap to cover the London Underground strikes earlier this month, the Guardian is using the tool to record reports of the Pope’s visit to the UK.

The map blends text, image and video reports from the Guardian’s own team with those submitted by readers and papal bystanders. There’s a certain tongue-in-cheek element to it as well, with categories for popemobile sightings and miracles alongside reports on protests and official news.

Explains the Guardian’s Paul Lewis in a blog post:

You can send anything, but we’re particularly interested in incidents, events and insights from people who find themselves at the right place at the right time, spotting something that the papal entourage of global media miss. It is important that you tell us where you are when you send your dispatch.

The majority of the updates plotted so far are from the Guardian, but it will be interesting to see how tools like this take off and how they might be further integrated into live reporting.
