<div dir="ltr"><div><div><div>Hello Steve,<br><br>I think I understand your questions, I am a GIS expert too. But when I take on a HOT task I ask myself, which features are critical to first responders?<br><br></div>First of all: Access. So I try to connect networks of roads an tracks accessible to vehicles.<br></div>Second: Possible human presence. So I map buildings. I do not go into details to much as I feel it is more important they know there is a building then what the building is shaped like. When I discover a group of buildings and I do not have time to map them individualy, I create a residential area. When I come across an existing residential area that is roughly shaped in a later task and I have time to map the individual buildings, I do that and reshape or remove the residential area.<br><br></div>And with these, I hope I help lay the basic structure for operations in the field.<br></div><div class="gmail_extra"><br><div class="gmail_quote">2015-04-30 8:28 GMT+02:00 Michael Krämer <span dir="ltr"><<a href="mailto:ohrosm@gmail.com" target="_blank">ohrosm@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Here a few quick comments to start with.

I'm guessing it was traced from different imagery (I checked Bing and MapBox, per the instructions) - I would not have traced much of it - too hard to see. Should I split this long way and label the second part 'highway=unclassified' or similar?</div></div></div></blockquote><div><br></div></span><div>Highway tagging can be confusing: If it is not suitable for a car it should be 'path' instead of 'track' while 'unclassified' is a minor road that does not classify for 'tertiary' or above. The tag for an unknown road is 'highway=road' but I hardly use that. If you want to know more about highway tagging I recommend [1] and/or [2].</div><span class=""><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div><div>(3) Some small hamlets of 5-10 buildings, accessible only by paths, are enclosed in existing 'landuse=residential' polygons. The validation instructions are to confirm there are highways connecting 'residential' areas, and that there are 'residential' polygons around clusters of "20 or so houses". Should I remove the 'residential' polygons around tiny hamlets that are not on roads?</div></div></div></blockquote><div><br></div></span><div>Again I would not delete them. I guess if there are building there likely is a path leading there but it might not be visible in the imagery. </div><div><br></div><div>Sometimes the instructions for tasks change or for subsequent tasks they may not be perfectly in alignment. Different mappers will always make different decision on what to map and what not. </div><div><br></div><div>Michael (user Ohr)</div><div>---</div><div>[1] <a href="http://wiki.openstreetmap.org/wiki/Highway_Tag_Africa" target="_blank">http://wiki.openstreetmap.org/wiki/Highway_Tag_Africa</a></div><div>[2] <a href="https://wiki.openstreetmap.org/wiki/Nepal/Roads" target="_blank">https://wiki.openstreetmap.org/wiki/Nepal/Roads</a></div></div></div></div></div>
