Through this mapping task the Netherlands Red Cross supports the Malawi Red Cross Society to:
reduce the prevalence of diarrhoeal diseases in the target communities of Phalombe.
enhance resilience and building institutional disaster response capacity training for the people of Malawi
raise awareness within vulnerable communities in disaster prone areas of the possible dangers of natural disasters.
improve the delivery of sustainable water supply, sanitation and hygiene services in 9 low-income areas
respond to a food crisis to meet drought affected population’s food and nutrition needs through cash transfer.
Mapping efforts are coordinated with local government / members of the HOT/OSM community in Malawi.
The Missing Maps project aims to map the most vulnerable places in the world (affected by humanitarian crises: disease epidemics, conflict, natural disasters, poverty, environmental crises). Building on HOT's disaster preparedness projects, the Missing Maps tasks facilitate pre-emptive mapping of priority countries to better facilitate disaster response, medical activities and resource allocation when crises occur.
This task was generated through Mapswipe. All satellite imagery has been reviewed for containing buildings.

- #hotosm-project-2472 #MissingMaps #Malawi #rodekruis #redcross #missingmapsmug When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".
Please click on a square to start mapping.
Please use the Bing Aerial Imagery that is default on this task. If you want to switch imagery, go to the Background settings in the ID-editor, click Mapbox Satellite.
This task was prepared with Mapswipe. Therefore, tiles are not square, but different shapes. For mappers that use ID, just select an area and start mapping.
For JOSM users. Please open JOSM, then download additional data here! After that you can select a task area and start mapping.
Buildings. Simply trace the outline of all buildings. A building should be tagged as a Building of type Building (because we don't know the exact function of that building from satellite imagery). Make sure you SQUARE (shortcut key = 'S' in iD editor) the corners of square/rectangular buildings.
If you cannot finish the tile due to cloud coverage, you can successfully complete the tasks, then save your changes, mention 'cloud coverage' in the comment when you save the task, and mark the task as done.
We kindly request advanced mappers and validators to contribute to validating the work of others. This task can only be completed when all tiles have been marked as validated (green). To validate, choose a tile marked 'done' (orange) and click 'review the work'. Open it in JOSM or the ID-editor. Correct any errors such as:
Map missing buildings.
Correct buildings. Some buildings are not properly drawn. See if you can correct them to match the shape of the building on the satellite imagery. If a building is not squared but should be, apply squaring to the buildings (this is most easily done in JOSM where all buildings can be selected and squared with one click.
If you finish validating a tile. Save your changes, mark it as validated in the HOT tasking manager, and leave a comment to the original contributors i.e.: 'thank you for mapping all these buildings and roads. We made a few corrections. Please consider squaring the buildings in your future work, and make sure that you don't miss any'
