<div dir="ltr">Hi Tim,<div><br></div><div>That sounds good to me, and I agree with using the Tasking Manager. I think we will want to make sure that the coverage of outlines is added consistently across the country - at the very least, seeing which areas have been done will speed up the process of identifying the next area to do, and prevent areas from being missed out.</div><div><br></div><div>That said, I'm not sure where/how we would get a Tasking Manager project set up - I know there are several hosted instances of the original HOT OSM version around the place but I don't know which one would be the most appropriate.</div><div><br></div><div>Cheers,</div><div>Andrew<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><br>Andrew</div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Apr 5, 2021 at 6:00 PM Timothée Duhamel <<a href="mailto:timothee.duhamel@gmail.com">timothee.duhamel@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Andrew,<div><br></div><div></div><div>I've been participating in Kyle H's address import, and I was considering what it could look like to use that approach (a custom RapiD instance which can handle different sorts of conflation) to the buildings import.

Initially I was doing a lot of my own additions through manual tracing, but I've slowed down on that as it feels like unnecessary work, knowing that there are high quality building outline datasets available. Many of you would have been involved in the previous imports of building outlines, which are in various stages of completion, and no longer active. For example, much of Auckland was never completed. I've been following the changes in data and technology available, and I believe there's an opportunity to begin a new building outline import.<br><br></div><div>So I am getting in touch with the NZ-OSM mailing list seeking the community's support to have the LINZ building outline dataset made available on RapiD.

The user can select the features and choose to include them in their changeset. Or they can choose to ignore a feature, for example if they know a building doesn't exist, or would rather draw it themselves. This means that the data is being added with a high degree of oversight, compared to other import processes, and users are restricted to adding only 50 features per changeset. There is also a JOSM plugin available.</div><div style="color:rgb(0,0,0)"><br></div><div style="color:rgb(0,0,0)"><i>How does it work?</i></div><div style="color:rgb(0,0,0)">I would suggest trying RapiD hands-on, to see how the suggestions work. I have been testing it in Australia, where they have had Microsoft Buildings available in RapiD since October. (I would note that the LINZ building outlines are of higher quality than the Microsoft data available in Australia)</div><div style="color:rgb(0,0,0)">Try RapiD here: <a href="https://mapwith.ai/rapid" target="_blank">https://mapwith.ai/rapid</a></div><div style="color:rgb(0,0,0)">Or the JOSM plugin instructions are here: <a href="https://josm.openstreetmap.de/wiki/Help/Plugin/MapWithAI" target="_blank">https://josm.openstreetmap.de/wiki/Help/Plugin/MapWithAI</a></div><div style="color:rgb(0,0,0)"><br></div><div style="color:rgb(0,0,0)"><i>Will this undo all my hard work drawing buildings already on OSM?</i></div><div style="color:rgb(0,0,0)"><b>No </b>- RapiD only suggests features where there is no existing feature already. Areas that are already well mapped will show very few, if any, suggestions.</div><div style="color:rgb(0,0,0)"><br></div><div style="color:rgb(0,0,0)"><i>Is this an import?</i></div><div style="color:rgb(0,0,0)">This is not a systematic bulk import like previous LINZ data imports, but yes essentially this is enabling users to perform small, manual imports. Having said that, I'm sure that a tasking manager project could be set up to have a more systematic approach to reviewing and importing the data.</div><div style="color:rgb(0,0,0)"><br></div><div style="color:rgb(0,0,0)"><i>Any risks?</i></div><div style="color:rgb(0,0,0)">The building outlines were generated from imagery up to 8 years old in some areas, so in those places there will be buildings suggested which have since been demolished. Correctly identifying and ignoring these features will depend on users having local knowledge or consulting more recent imagery when manually adding the buildings. Also there are false-positives where caravans, shade sails, canopies have been digitised as buildings - again these could be picked up by the user when manually reviewing the buildings.</div></div><div style="color:rgb(0,0,0)"><br></div><div style="color:rgb(0,0,0)"><br></div></div>
