[OSM-talk] Earthquake in Christchurch NZ last weekend
As a recent migrant to the UK to Christchurch I can say it was a pretty scary experience and thank providence that it was at 4.35am and not 4.35pm!!! To characterise the damage as widespread is a little media spin - there is some serious damage, especially to historical, brick buildings in the centre and surrounding suburbs and I suppose it is over a wide area, however I would estimate that 99.9% of the city is fine. What is interesting is that you can be on one street and everything is normal , you turn the corner and it looks like a bomb site for 100 metres then it is normal again. Kaiapoi, a small town of 12,000 just north of Christchurch, has not fared so well with over 400 homes condemned. Yet Woodend a few km's further up the road is virtually untouched. That I think has been the biggest surprise to the people I have spoken to - the small pockets of carnage in an otherwise unscathed environment. I sure that many papers and thesis will be written on why this phenomenon occurred as well as some serious re-evaluation on type of soil/bedrock that it will be permissible to build on. The event bought to mind a childhood song The Wise Man Built His House Upon the Rocks. Building on sand in a known earthquake zone was perhaps a misjudgement. The word of the week is liquefaction - there is a great video here a 1964 that shows how the soil just turns to liquid, just as it did in Kaiapoi http://www.youtube.com/watch?v=KLZFlnND0hA Anyway here is a great site that shows an time-line animation of the quake and aftershocks http://www.christchurchquakemap.co.nz/ There have been around 400 aftershocks so far, mostly unfelt, the bigger ones are listed here http://lists.geonet.org.nz/pipermail/eqnews/2010-September/ Phil Message: 9 Date: Thu, 9 Sep 2010 16:53:01 +0900 From: Andrew Errington a.erring...@lancaster.ac.uk To: talk@openstreetmap.org Subject: [OSM-talk] Earthquake in Christchurch NZ last weekend Message-ID: 201009091653.02041.a.erring...@lancaster.ac.uk Content-Type: text/plain; charset=us-ascii In case anyone missed reading about it, there was a 7.1 magnitude earthquake in Christchurch, New Zealand at the weekend. Miraculously no-one was killed, despite widespread damage. This was due mainly to the fact that it happened in the early morning, so people were asleep in their homes. If they had been walking or driving through the city when it happened I am sure there would have been many injuries and deaths (and more news coverage). Anyway, a helpful individual has made this: http://www.mapquake.co.nz/ And someone from ESRI (I think) in NZ has made this: http://s1.demos.eaglegis.co.nz/Flex/earthquake-christchurch I cannot find anything based on OSM, although I am not suggesting that someone should do this, since it seems that is already covered. It's interesting, however, to see the UIs that are being used, and also how willing the general public is to contribute useful information to such a site. My questions are, is someone or some group using OSM as the data source for similar public information services? Are there tools for people to make such webpages easily using OSM? Is OSM ready for this? I apologise if this topic has been discussed in depth elsewhere. Best wishes, Andrew ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] OpenRouteService for Haiti Online
Hi Alex, Is there any tagging that I can add to highways that appear blocked according to the latest GeoEye so that you automatically identify the highway as an AvoidArea? Thanks Phil Hello A first OpenRouteService Site (Routing/Geocoding) is up and running for Haiti, it supports the definition of AvoidAreas e.g. blocked areas http://openls.geog.uni-heidelberg.de/osm-haiti/ Thanks to Pascal Neis, Joe Lauer and the rest of the team! ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

And that means: it's time for Potlatch 1.0. Just had a play - both offline and live editing and wow - it's lovely. Seems to be lots quicker too... Great job Regards Phil ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

[Talk-us] Temporarily Deleting Relations from Interstate Ways
Hi, For the last couple of months I have been working by way along each of the Interstates (starting at H1) and am currently 2/3rds up the I5, checking the one-ways, putting in/fixing all the bridges and tunnels and checking the junctions etc based upon Yahoo imagery and the TIGER data. Before 0.6 I was making great progress, but since the upgrade things have really slowed down. It is now taking me a good 30 seconds, often more, just to split a way - each bridge takes at least 2 mins to define - there are a lot of bridges and complex junctions!!! Reading other lists I see that this is a know issue with Potlatch and large relations, with no immediate solution available. My idea is to temporarily delete the relations from the highway I am working on, and then add it back on when the changes are complete. Bearing in mind that sometimes it might take a few weeks to complete - I'm really looking forward to I-10 at 2.4k miles Any thoughts, objections, better ideas..please don't say JOSM..

Re: [Talk-us] Temporarily Deleting Relations from Interstate Ways
Regarding JOSM - I specifically wanted to avoid a fight between the Potlach vs the JOSM crowd ;-) At the moment I am getting Exception Occurred with yahoo images - I'll redownload webkit tonight (Europe time) and see if that fixes it. If you're working on Interstates as well we should coordinate to avoid duplicate work.

For simple stuff like this it is pretty easy to use. If you have a specific gripe against JOSM, let me know -- I'd be happy to help you work through it. If you just don't like it, I don't think there are any other editors out there that are as feature-complete as Potlatch or JOSM. Also, I vote that you don't remove relations just to make editing easier. It would be a pain to add those back. -- Regards Phil ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [Talk-us] Temporarily Deleting Relations from Interstate Ways
I was looking at this page http://wiki.openstreetmap.org/wiki/JOSM/Plugins/WMSPlugin dunno if it is painless as my firewall is currently blocking the webkit download. http://wiki.openstreetmap.org/wiki/JOSM/Plugins/WMSPluginPhil Is there a wiki page on how to get the Yahoo imagery into JOSM painlessly? That's the primary reason I used Potlatch when fixing up bits of I-80/81 around here. -Ted ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [OSM-talk] Mantigue island swallowed by the sea
Mantigue is now rendered :-) I don't know how it happened, but when I pulled it into josm and ran the Validator it told me that the coastline was not completely joined - so I disconnected the last and first node of the way, rejoined them and voila. -- Regards Phil ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Metro Manila Philippines needs some OSM love
I have started this section on this page: http://wiki.openstreetmap.org/index.php/Yahoo!_Aerial_Imagery#Problems_with_tracing_Yahoo Many of the suggestions require ground knowledge. Reading the section pointed to above, it states Roads are unnamed, so the highway=road tag should be used, until either on the ground classification or someone who knows the area comes and updates the data. But this is not compatible with the How to Sketch section 3 paragraphs above - here it states that using a highway tag is not recommended. As someone new around here I am not sure if I have been doing the right thing now - I have been setting highway=road note=yahoo image Regards Phil ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
