The scope of the polio outbreak response (OBR) for detected wild polio virus type 1 (WPV1) in Borno State has been expanded and different strategies employed to reach eligible children in Nigeria. The immunization campaign which commenced on 17 September, 2016 is targeting 31,540,054 children in 18 states across northern Nigeria.

Baseline data (residential areas and road networks) over this large affected region are needed for the various actors engaged in the response of this complex emergency. Several OSM initiatives have been lead in some areas (Nigeria's eHealth Africa data imports, mapping by local OSM groups from Niger and Cameroun, as well as the efforts of individuals) and individual efforts are still continuing. Discussions with humanitarian actors highlighted the relevance of OSM data in this crisis and the need for a continued effort.

The area of Northern Borno is one vital area where this a coordinated effort for the Reach Inaccessible Children (RIC) and Reach Every Settlement (RES) initiative which is an integral part of the Emergency Outbreak Response for Polio in Nigeria.

Changeset Comment
When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".

The aim of this project is to map in details the road network and the residential areas for this region for the Reach Every Settlement (RES) and Reach Inaccessible Children (RIC) initiatives which is an integral part of the Emergency Outbreak response for Polio in Nigeria.

Roads and Paths

• Please map roads and major paths by connecting them to the main road networks wherever possible. • Very short segments that do not connect to anything should not be mapped. • Try and map a little beyond your task square so the person who maps the task square next to yours can easily connect them. • Always connect roads to other roads where they meet and never end roads on Residential area polygon edges. Use the Highway Tag Africa wiki as reference for road mapping and classification.

You will most often use the following road classifications:

• highway=unclassified - This is for roads that a vehicle with 4 wheels could travel on that connect small villages and settlements

• highway=track - This is for roads that a 4 wheel vehicle or farm tractor could travel on and only lead to farm fields or forests. They do not connect settlements.

• highway=path - This is for small paths that a 4 wheeled vehicle could not travel on and are usually used by people on foot or 2 wheeled vehicles. They may or may not connect settlements or lead to farm fields. Only map the major paths that connect to settlements or other roads.

Residential Areas • Please draw one large area outline around groups of buildings and tag them landuse=residential • About 5 or more buildings can be outlined as a landuse=residential area. • Do your best to keep the outline close to buildings and not include a lot of farmland or forest. • When to draw the residential area outline takes some judgement, but when in doubt, draw an outline around the settlement

General Mapping Notes

Be as precise as possible - This takes a little bit of practice, but following a road closely really makes a difference in the quality of map data produced. Quality is more important than quantity when it comes to mapping. Zooming in close helps.

It is ok to "split" task squares - Sometimes a task square will have a lot detailed settlement mapping. If you think it would help to make the task square smaller so the mapping could be finished in a more reasonable time, use the "split" link above the task square comment box.

Personal knowledge - If you have local knowledge, that is incredibly valuable and any information you are 100% sure of you can add to the object you are mapping. Building names, health facilities, names of roads, etc, are all very valuable and the name=* tag can be used to supply that information.

Sometimes a task square is already mapped - Sometimes you will find a task square that looks totally mapped or has nothing in it to map. Just double check that it is complete, map anything that was missed, straighten up anything that needs it and then mark it "Done".

Invalidated task squares - You might get a notice that a task square was "invalidated" that almost always just means someone found a few more things to map and they did not have time to map them in. No worries, it is part of the process and happens all the time. If you have to stop mapping before you have mapped everything use the "Unlock" link instead of "Done" As long as you are trying to map everything in a task square you feel confident mapping before you mark one "Done" then all is good.

Ask questions - if you have questions, please ask. The front page of this HOT Tasking Manager website offers a few ways to ask or if you are at a mapping event, raise your hand and ask.

You are making a real difference mapping - Every contribution matters in a real, tangible way. Mapping in not easy but know that your mapping is used by humanitarian organizations around the world every single day.
