Finding volunteers or reporting on local conditions in a time of crisis are the goals of two new applications. "Nasy," an app released in the Middle East, allows people to match their skills with local volunteer projects and find other volunteers nearby. Meanwhile, a company called Ushahidi has created a website that uses crowdsourcing to map unrest in Kenya and other hot spots. Users can submit information over the Internet and smartphones to create an "activist map" through Google Maps. "Whether you're simply seeking to get the vote out, find local workers, or struggling to share the news of a crisis from on the ground to the rest of the world, location-based services can help," Asif Khan writes.
