<div dir="auto">Buildings Canada?<div dir="auto"><br></div><div dir="auto">I was involved with something in Ottawa. I deliberately used JOSM and the building tool plugin. It went very smoothly and a fair number of buildings were accurately mapped. The mappers were requested to come with JAVA preinstalled. I had two laptops set up that new mappers could start off with and we had sufficient resources that we could take them fairly quickly through the steps and get them mapping. The number of buildings mapped per new mapper was in the order of 60 per minute.</div><div dir="auto"><br></div><div dir="auto">Make sure you have spare mice with you.</div><div dir="auto"><br></div><div dir="auto">There were a number of other mapathons as part of geoweek that used iD. Unfortunately the quality of mapping was not that high leading to compliants about the data quality.</div><div dir="auto"><br></div><div dir="auto">Building numbers from mapathons from new mappers anything from four to twenty buildings each. This is from cleaning up in currently Malawi where a fair number of iD mappers are still not managing to tag a building with building=yes.</div><div dir="auto"><br></div><div dir="auto">If you are running just one session then validate by looking over their shoulder. If more than one line up some resources to quickly validate and use JOSM for this. The faster the feedback the better the response.</div><div dir="auto"><br></div><div dir="auto">If you are thinking of grading the work watch out for someone coming along and either correcting the work as in validation or simply deleting it from a quality point of view. Remember that some GIS people like to do population estimates based on the square meters of the buildings so accurate mapping helps. Buildings that are mapped at twice the proper size screw up the population estimates.</div><div dir="auto"><br></div><div dir="auto">Have fun.</div><div dir="auto"><br></div><div dir="auto">Cheerio John</div><div dir="auto"><br></div><div dir="auto"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 23 Jan 2018 7:46 pm, "Jonathan Brown" <<a href="mailto:jonabrow@gmail.com">jonabrow@gmail.com</a>> wrote:<br type="attribution"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-US" link="blue" vlink="#954F72"><div class="m_673408815197180973WordSection1"><p class="MsoNormal">Looking for anyone who has done a BC2020i mapathon event with high school students.
