<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">I've found picking out rivers and streams to be slightly problematical. If I zoom out then I can see a string of green which I assume is trees and vegetation along the bodies of water. Could someone knock up a video training guide on how to pick things out for us city dwellers on You-Tube or something and how to tag a body of water?<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Thanks John <br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 22 November 2014 at 21:59, Mark Cupitt <span dir="ltr"><<a href="mailto:markcupitt@gmail.com" target="_blank">markcupitt@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Dear All</div><div><br></div><div>The World Health Organization (WHO) and the Center for Disease Control and Prevention (CDC) need all rural Cameroon mapped in response to the Polio outbreak and also monitoring and preparing for a possible Ebola outbreak.</div><div><br></div><div>A New task has been created to assist with Round 2 of this project using High resolution imagery supplied by DigitalGlobe’s WorldView-2 service available on the Mapbox Satellite Layer.</div><div><br></div><div><br></div><div><b><a href="http://tasks.hotosm.org/project/777" target="_blank">http://tasks.hotosm.org/project/777</a> </b></div><div><br></div><div><br></div><div>Please assist these organizations by mapping the following:</div><div><br></div><div><ul><li>villages/residential areas (Polygons tagged landuse=residential)<br></li><li>roads, streets, paths (tag roads according the Highway Tag Africa wiki page)<br></li><li>water bodies, rivers, streams and forests</li><li>open areas (not fields, just smooth open ground next to towns) as leisure=common as these are potential helicopter landing sites. </li><li>school areas, easily identified as 1 or 2 long buildings at the edge of the village often with two small toilet buildings behind them.

The outbreak continued into 2014, with international spread to Equatorial Guinea. In March 2014, WHO elevated the risk assessment of international spread of polio from Cameroon to very high, due to expanding circulation and influx of vulnerable refugee populations from Central African Republic (CAR). This risk assessment remains in place. Further undetected circulation in Cameroon cannot be ruled out. Moreover, the risk of virus spreading into CAR is considered to be particularly high given the large-scale population movements from CAR into Cameroon.</div><div><div><div dir="ltr"><div><br></div><div>Regards</div><div><br></div><div>Mark Cupitt</div><div><br></div><div>"If we change the world, let it bear the mark of our intelligence"</div><div><br></div><div><a>Hire Me on Freelance</a>r </div><div><a></a><span></span><span></span><div><br></div></div><div><a href="https://www.openstreetmap.org/user/Mark_Cupitt" target="_blank">See me on Open StreetMap</a><br></div><div><br></div><div><a href="http://ph.linkedin.com/in/markcupitt" target="_blank">See me on LinkedIn</a></div><div><img src="http://s.c.lnkd.licdn.com/scds/common/u/img/webpromo/btn_myprofile_160x33.png"><br></div><div><span style="font-family:'arial black',sans-serif"><b><br><a href="http://gis.stackexchange.com/users/17846/mark-c" target="_blank">See me on StackExchange</a></b></span></div><div><img src="http://gis.stackexchange.com/users/flair/17846.png"><br></div><div>===============================================================================================</div><div>The contents of this email are intended only for the individual(s) to whom it is addressed and may contain</div><div>confidential or privileged information.
