<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">One final comment that has been mentioned before is that many mappers are mapping on laptops without a mouse so their control isn't that good. Add in iD without a building plug in like JOSM and you get the very odd shaped buildings we see on the map. They can be squared but that is another approximation.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">JOSM with the building tool plug in is seen as too complicated by many mapathon organisers.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Cheerio John <br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 15 November 2016 at 14:13, john whelan <span dir="ltr"><<a href="mailto:jwhelan0112@gmail.com" target="_blank">jwhelan0112@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 class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Looking at the other half there are only 3,000 untagged ways. In general it doesn't look too bad but yes there are some areas that might not meet a desired standard.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">I think the problem is three fold, first experienced mappers who map as they would in Europe without regard to the <a href="http://wiki.openstreetmap.org/wiki/Highway_Tag_Africa" target="_blank">http://wiki.openstreetmap.org/<wbr>wiki/Highway_Tag_Africa</a> or the convention that huts should be mapped as an area rather than a node. These aren't a major problem as the quality is otherwise fairly good.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Second mapathon or inexperienced mappers not knowing what they are doing. Validation helps here if you give them feedback you get more out of them and its better quality but you need a validator who knows what they are doing and don't even try and validate in iD. One major difficulty is that many new mappers will not finish a tile which makes their work more difficult to spot when validating. If you can ask them nicely to map from the top then it gives someone a chance to go over their work without having to scan the entire project.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">However we don't have enough validators, especially ones who can give feedback without turning the mappers off. To be honest when faced with another seventeen new mappers sixteen of which you know will probably only map once validating their work isn't that rewarding and its faster to map it yourself than to do a full validation feedback.<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br><a href="http://tasks.hotosm.org/project/1396#" target="_blank">http://tasks.hotosm.org/<wbr>project/1396#</a> is an example of a validated project. We still get new mappers and mapathons on there but the quality isn't too bad. We also have a pair of very nice mappers who cleans up tiles that have been marked invalid because they're incomplete.<br><br><a href="http://tasks.hotosm.org/project/1087" target="_blank">http://tasks.hotosm.org/<wbr>project/1087</a> is another project that gets a lot of validation, its big but at the moment it seems to have attracted the attention of a local mapper and developing local expertise is always a good thing.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">I think the third cause in Africa is the variety of local languages used, they aren't all supported in the training guides and wiki. Local mappers are not supported as well as they could be.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Training helps, but not every mapathon has it nor do all the organisers know much about OSM. Projects that are limited ie buildings or highways and settlements mean there is less information to absorb by new mappers.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Cheerio John <br></div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On 15 November 2016 at 08:26, john whelan <span dir="ltr"><<a href="mailto:jwhelan0112@gmail.com" target="_blank">jwhelan0112@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 class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Looking in JOSM at half Tanzania there are some 4,000 untagged ways, 26,000 duplicated nodes etc.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">I'll take a look over the next few days.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Cheerio John<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="m_-5834491784893496332h5">On 15 November 2016 at 01:12, Douglas Ssebaggala <span dir="ltr"><<a href="mailto:douglas.ssebaggala@hotosm.org" target="_blank">douglas.ssebaggala@hotosm.org</a><wbr>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="m_-5834491784893496332h5"><div dir="ltr">Dear community members,<div><br></div><div>While at the <a href="http://i2ifacility.org/Spatial_Data/" target="_blank">spatial data workshop</a> a few days back in Tanzania, there was unique feedback from some of the people and organisations who have used OSM data: they greatly appreciated the quality of the data in OSM: buildings, roads, and business information, e.t.c thanks to the Ramani Huria team, and community members who are doing the mapping.</div><div><br></div><div>This <a href="http://www.worldpop.org.uk/" target="_blank">data is being used</a> for analysis, insight generation and maps!!
