It’s only been a decade since we have access to satellite maps of the world using web-based cartographic products. Until recently, we only used official cartography. Google Maps and Google Earth have allowed us to easily view and navigate cities from our personal computers and cell phones. Not only are we able to consult maps on our cell phones, but we can also make collective maps through online crowdsourcing software. Today, we can take aerial photographs with small, easy-to-use, remote control helicopters. This technological revolution has challenged the field of cartography and allows ordinary citizens to visualize and create maps of places that have remained unmapped. Such is the case of most of the informal settlements spontaneously developed without an urban plan.
