    Abstract : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. READ MORE

    Keywords : Communications; Development; ICT4D; Volunteering; Slacktivism; crowdsourcing; data; humanitarian; mapping;

    Abstract : In the wake of the Haiti earthquake response in 2010, crowdsourced humanitarian mapping has taken off, and today is considered an essential tool by many humanitarian agencies providing assistance in disaster-affected and under-resourced countries and contexts. But what happens when there is no information on a map to help agencies decide how to respond? If they cannot find roads to take to get there? If they do not know how many houses are in a village? What if the map is – missing? In response to this all-too-common problem, Médecins Sans Frontières (MSF), American Red Cross, British Red Cross and the Humanitarian OpenStreetMap Team (HOT) created and launched Missing Maps in 2014.
