Just reposting a comment that I made earlier today (re Syria, but apropos here too): IF you have some free time, the Humanitarian Openstreetmap Team (HOT) is always looking for volunteer mappers. The current ebola outbreak is the #1 priority for HOT. Tracing buildings, roads, and other features from aerial imagery is something that anybody can do, and it provides immediate benefit to volunteers from the World Health Organization (WHO), Doctors Without Borders (DWB/MSF), IFRC and other humanitarian organizations on the ground responding to the crisis. To map something now: http://tasks.hotosm.org/ http://tasks.hotosm.org/ More on HOT: http://hot.openstreetmap.org/get-involved http://hot.openstreetmap.org/get-involved "HOT benefits from contributors with a wide range of interests and experience. Almost anyone can make a tremendous contribution to our projects by contributing mapping, but we're also very pleased to hear from developers, documenters and ideas hackers that can engage with us and our work."
