As part of the OpenStreetMap project, there is a humanitarian aspect, producing maps of the less developed parts of the world. These can be used for both disaster recovery, as was demonstrated after the Haiti earthquake, but also for preparedness in areas of flood or disease risk. Maps are knowledge. They are required to coordinate… Continue reading Mapping the developing world

The feature I use most is the various background image layers, but also being able to quickly loading my GPS tracks and support for other plugins are… Continue reading OpenStreetMap editing with JOSM
