<div dir="ltr"><div><div>Well we can certainly get on with the website. The bits that people fix are only the major issues (processed as individual buildings) so I don't think they'll fix any "terrace gap" issues. I was hoping to use Strava Slide before people start manually fixing but we could always do it after instead (and then just eyeball it ourselves for any new errors).<br>
<br></div>So we can ignore the old github repo and use the new one then? I'm busy this week but will aim to look at the website from next week. If anyone has some good images we could use in place of the default NYPL ones then shout :-)<br>

<br><ol><li>Chris Fleet from National Library of Scotland (NLS) has kindly provided a couple of GeoTiff example scans from their London 1890's maps [2].</li>
<li>Using the NYPL map-vectorizer [3] I am able to get initial building outlines from these maps.</li><li>Tim Waters has managed to get a copy of the NYPL website up ready for loading NLS's maps/vectorized buildings. This is at [4]. Meanwhile he has opened initial conversations with the British Library who also have a good collection of historic maps.</li>
<li>I am concerned that the initial building outlines end up leaving gaps between terraced buildings. This is due to the way that the NYPL map-vecotrizer works to trace the _inside_ of buildings. I'm no GIS expert so may be missing a simple solution. However I have noticed that we could use the Strava Slide tool [5] to 'slide' the building polygons onto the building walls. In essence this works by using pixel "blackness" of the map scan (rather than GPS traces as per the initial Strava Slide tool).</li>
<li>I have contacted Paul at Strava to ask about this. He thinks the idea is a really good one and is hoping to add the functionality we will require. He's a bit busy at the moment but is presenting at FOSS4G (in September?) and would like to use this as an example of what's possible with slide.<br>
</li></ol>So, where does this leave us? Well we're at the same place as NYPL so could go ahead with adapting the website Tim put up to our needs and then launch when ready. Or, we could hold off until Paul at Strava is able to add the functionality we need to the Slide tool.<br>
<br>Thoughts?<br><br></div>Also, are folks happy for this to be branded as an OpenHistoricalMap project? (Chris at NLS is okay with this).<br><br></div>Regards,<br>Rob<br><div><div><br>[1] <a href="http://buildinginspector.nypl.org/" target="_blank">http://buildinginspector.nypl.org/</a><br>
