OpenStreetMap diary entries for AndrewMcCarthy Recent OpenStreetMap diary entries from AndrewMcCarthy OpenStreetMap 100 100 Irish Regional Roads and NLS Historic Maps <p>In the last few days I've been browsing through the map, with the SI 188 of 2006 in one window, and the NLS Historic Maps in the background of JOSM. I've corrected a bunch of road refs, and managed to add or complete a few other roads that were completely missing through Counties Cork, Kerry, Limerick, Clare, Tipperary, Waterford, Donegal, Cavan and Monaghan.</p> <p>I think the list on the Wiki needs two separate completion columns, one to say "an armchair mapper can see that everything listed in the SI seems to be there" and "somebody on the ground has confirmed this is actually correct".</p> <p>Oh, and where exactly does the R162 really go when it heads north of Shercock? No sign of Lisdrumclave on the historic maps. Ta. :)</p> <p>I'm also not convinced that R268 in Donegal is right. Doesn't seem to match the description.</p> AndrewMcCarthy Sun, 04 Dec 2011 23:39:25 +0000 Irish M9, Junction 2 to 4 <p>Took about an hour to drive (including the new bit of R747) and nearly two hours to trace (I'd swear there's not a single straight bit longer than about 300 metres in the whole 27-ish km each way), but it's pretty much done. A few missing details such as whether some of the back roads go over or under the motorway. I'm missing traces for southbound through J3 (I came off at that point) and northbound through J2. Also need through-traces for J4 in both directions, but it's easy enough to guesstimate close enough.</p> <p>Will upload my GPX traces tomorrow when I'm less tired.</p> AndrewMcCarthy Wed, 23 Dec 2009 00:11:17 +0000 52.998274804373 -6.8407974582111 52.998274804373 -6.8407974582111 Lisbon to Madrid by rail: GPX trace! <p>I was lucky to travel by overnight train from Lisbon Santa Apolonia station to Madrid Chamartin last week. I was able to keep my N95 by the window for nearly the entire journey and have uploaded a 15102-point GPX trace. There are a few glitches near tunnels, etc, but it looks quite good.</p> <p>It's nearly 800km long! Would anybody like to help "nudging" the landsat-traced line into place?</p> AndrewMcCarthy Tue, 30 Sep 2008 11:52:33 +0000 N7, Limerick and Birdhill <p>Found some new arrangements at the Limerick end of the N7. There's a new roundabout in Birdhill, and the layout at the N7/R445 (often called Finnegan's Roundabout) has changed.</p> <p>While I was at it, I waypointed a new M7 bridge near the Nenagh bypass as I drove under it, and drew a rough highway=construction bridge at this point. The location should be pretty close, but the angle is fairly rough...</p> AndrewMcCarthy Mon, 01 Sep 2008 21:05:34 +0000 52.6734862568567 -8.5154400210099 52.6734862568567 -8.5154400210099 Lots of bits in County Tipperary <p>Spending a great weekend in Tipperary, we covered quite a few roads. I've now completed the R668 (Cahir to Lismore), which towards it's southern end is a mixture of great scenery at The Vee, and some truly awful roads — narrow, very twisty, bumpy, and overshadowed with trees. My GPS traces in places drift apart (we were on it three times!), so more traces would be good. It's worth seeing, anyway!</p> <p>I also managed to complete the related R669, and identified an existing road on the map as the R670. Conversely, I found a trace in the database with no way that turns out to be the R665 from Clogheen to Mitchelstown, so that's nearly complete too. Some other fragments in Cashel, including an off-ramp from the N8 made for a reasonably productive mapping weekend.</p> <p>Does anyone know what the N24 through Cahir is now classed as (it appears the N24 has moved to a bypass, although I never saw it personally)? I'm guessing R527, but it's still signposted as the N24. For the hundreds of millions of euro they spend, the NRA never seem to have a budget for re-signing the old roads...</p> AndrewMcCarthy Mon, 04 Aug 2008 21:35:03 +0000 52.2618725809534 -7.97719577359478 52.2618725809534 -7.97719577359478 SOTM &#39;08 <p>Many thanks and congratulations to all involved in organising a great weekend!</p> <p>It was fun to meet up with other mappers, and to see all the work being done on mapping, promotion and some very neat applications. The workshop on relations was also reassuring — it's not just me that's not sure what to do with them!</p> AndrewMcCarthy Sun, 13 Jul 2008 22:40:42 +0000 52.6687857810936 -8.5532350282372 52.6687857810936 -8.5532350282372 Big Limerick classification clean-up <p>Starting from a post on the talk-ie list about the old N7 in Limerick, I began picking through the data and remarking it as the R445. As I was going along, I noticed junctions with other roads, and thought I'd check them too. And then I checked what was attached to them...</p> <p>In the end, the list below is what I updated:</p> <p>∘ Fixed Old N7 to R445 <br>∘ Fixed N20 route into city, still unsure within city (think it's okay) <br>∘ Added R509 (half of Childers Road) <br>∘ Added R510 (first half, suspect the other half is on the map, but not enough data to be sure) <br>∘ Added R526 (old N20) within Limerick <br>∘ Added R527 (old N24) within Limerick <br>∘ Corrected start of R463 <br>∘ Added R857 (Ennis road) <br>∘ Added R858</p> <p>Limerick still needs lots of work! If anybody is living down there (I don't) please, in particular, mark the one-way streets if you can. The Osmarender maps should update soon.</p> AndrewMcCarthy Fri, 25 Apr 2008 10:59:48 +0000 Tiles@Home tile information bookmark. <p>In Firefox, create a bookmark with this location:</p> <p>javascript:var%C2%A0s='%s'; url='<a href=";y=%s&amp;z=%s" rel="nofollow">;y=%s&amp;z=%s</a>'; t=''; qc=0; chunks=url.split('%s'); for(i=0; i');</p> <p>and set the bookmark keyword to something like "tah". You can then go the location bar and enter "tah" followed by the x coordinate, y coordinate and zoom level of the Osmarender tile you're interested in. For example:</p> <p>tah 1976 1327 12 <br>sends you to <br><a href=";y=1327&amp;z=12" rel="nofollow">;y=1327&amp;z=12</a></p> AndrewMcCarthy Mon, 21 Apr 2008 22:34:21 +0000 Align those overhead photos, folks! <p>A lot of the time overhead photos from various sources aren't perfectly aligned, and may be off by 50–100m. Please make sure to align them by comparing features in the photo with actual GPS tracks in JOSM (or whatever you're using) before you trace rivers and buildings. :)</p> AndrewMcCarthy Fri, 11 Apr 2008 18:40:31 +0000 Test lowzoom for Ireland and Isle of Man <p>Hi folks,</p> <p>I've done a trial run of building lowzoom (levels 8 to 11) tiles for Ireland and, consequently, the Isle of Man. It seems to have worked fine except for the coastline at the very North, near Derry, and the South, between Cork and Waterford. Has anyone else had a problem like this? It seems to mainly occur at zoom level 8, and only to a very small degree at higher zoom levels: <br> <a href=";y=80&amp;z=8&amp;layer=tile" rel="nofollow">;y=80&amp;z=8&amp;layer=tile</a></p> <p>(And this is my first diary post :)</p> <p>Andrew</p> AndrewMcCarthy Sun, 06 Apr 2008 22:03:27 +0000
