When deleting A15 roadways in tiger data, you will find to your dismay that the offending roadway extended over a couple of tiles. Seems major roads in tiger, as brought in to O.S.M. are Verrrrrry long. What does Tiger say?
Meow.

Probably been a few months since I surveyed any new streets around town, but got on the road after work the other day, and filled in a whole neighbourhood. Gerði, check!

After reviewing the map today, and looking at my notes, it seems there's only one neighbourhood, around kringlan, and a couple of forgotten streets in Suður Hlíðar, and all of reykjavik north of Bústaðavegur will be complete. Hooray! I've also made a note of a couple of the on/off ramps that need to be driven in different directions to complete them. And tonight, I'm off out in the country to a new location, should be fun!

Circuitous route to the sandwich shop this lunchtime via Headington Quarry - not an area I'm familiar with - and finding all sorts of hidden footpaths, parklets, allotments, and the usual small-scale stuff. Oddities: one tiny Assemblies of God[1] chapel about the size of a small shoebox.

[1] The Jimmy Swaggart lot, unless that's some other sub-cult^Wsect.

Test Performed using a few streets in the city center.

Taking a look at the Mallorca traces and asking for help to some friends living there. http://mitago.net/archives/2008/03/10/T20_16_44/index.html

Fortunately the main city has good YWMS photos so I will add some mapping inthere. Also im defining the coastline.

Echando un ojo a las trazas de Mallorca y de paso pidiendo colaboraciones a algunos amigos viviendo allí. http://mitago.net/archives/2008/03/10/T20_16_44/index.html

Además, por suerte, Palma y alrededores tienen fotos de YWMS de muy buena resolución, así que mapear la ciudad con los nombres de las calles que conozco puede ser fácil.
De paso estoy definiendo algo más la coastline usando las mismas fotos.

I've been trying to find some easier ways to clean up the Tiger data for my area around Portland, Oregon. I've been corresponding with a few others also trying to do the same thing.

I'll skip to the punchline first: Better JOSM layers for aerial photos at

http://terraservice.net/ogcmap.ashx?version=1.1.1&request=GetMap&Layers=urbanarea&Styles=&SRS=EPSG:4326&format=image/jpeg&

and public street maps from the county tax office at

http://columbo.nrlssc.navy.mil/ogcwms/servlet/WMSServlet/Portland_OR_Metro_Maps.wms?VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&LAYERS=0:42&FORMAT=image/png

Here's the long version of the story:

For my county, I've found excellent position consistency among all data sources other than Tiger. My GPS readings match the Yahoo aerial photos, Google Earth, Washington County tax maps, Beaverton city maps, and the USGS urban area photo maps at terraservice.net. The Tiger data is broadly correct with pretty much all the right streets in the right relationships, but it is often shifted out of place by varying amounts.

So everybody agrees except Tiger. This is good, in that it gives me confidence in the other sources, meaning I don't have to travel every single street with my GPS since my tax dollars already did so. I figure that if I get a large rectangle by GPS which matches the aerial photos, then the area within the rectangle can be aligned with just the photo. I've been looking for the most efficient way to do that. Sometimes the Yahoo aerial photos are not as clear as I would like, such as being obscured by trees.

Although I like the simplicity of Potlatch, I found I really need the multiple-node selection and movement capability in JOSM for realigning the Tiger data. The key, then, has been to find better sources of public data which I can use as WMS layers in JOSM.

I'm rewriting the tag editing code in Potlatch to be a bit more reliable at the moment... and it's taking longer than expected. So, sorry for the lack of updates. 0.8 will be along as soon as I can finish it...

Keep an eye on the status of mapping Aurora at:

Just bought a new GPS logger to replace my old BT-338 receiver that drowned in my car. I must say that precision has improved drastically. I am now able to see when I have moved around a parked car, parked myself, .. It's almost too detailed, because I now have to take care to stay really on one lane to get a straight track..

Still love it though :)

I'll add a review to the wiki in the coming weeks. Hope that my experience stays this positive. Very happy to be mapping again after a detox period of 3 weeks (with addiction pains).

I've just gotten into OSM in the last couple of weeks. Since I live in Hillsboro I've been working on streets around Hillsboro: making corrections from TIGER data and adding new construction. I've been using Potlatch, but played around a little bit with JOSM.

I've been using Washington County's GIS system for info: street names and routes, as well as eliminating private streets. I would really like to find a way to overlay arbitrary images from this or other GIS systems onto the editor. Anyone know a way to do this?

Thanks

I'm working on mapping Zagreb, but I see there's lot of job left to do to map Zagreb completely. Hope I will have more time in the future to finish what I've started.

Test! =)

I've been playing with making a 3D model of the piste data I collected at Isola 2000 ski resort. Taking the GPS tracks that include elevation data and combining them with the ways that I plotted into OSM I've written a little application that will render the resort as a 3D image that can be rotated, zoomed etc. Still a work-in-progress and unlikely to every be generally released, but I'm having fun making it.

Well, almost - a couple of tiny roads in West End (out from the main town) aren't done. But everything else is. Coupled with messpert's amazing work in Witney and the usual suspects around Woodstock et al, West Oxfordshire could be complete before too long...

Lots of gpx uploads and fixing in the main roads, usually traced very roughly and now adjusted to the gpx track. A-1, A-2, A-6, N-I, N-II and the traversal A-231
Still a track near Vitoria is marked as N-I trunk instead of a double way motorway A-1
Also some pending tracks near Valladolid.

Definitly is needed to add the source tag to know the fiability of the tracks

Yesterday another tour by bike to complete the village of Rußheim - again, bad GPS reception, so the data may be a little inaccurate. Now all villages north of Karlsruhe up to Rußheim are complete :-) - GPX-Track: @flschm/traces/82721

A few days ago, I started mapping lakes in the Gothenburg region along the Swedish west coast. The goal is to map all of the ones present in the Yahoo hi resolution imagery in the next few months.

Yesterday a little bicycle ride to complete Rußheim / Dettenheim north of Karlsruhe. Experienced some GPS problems due to cloudy sky. Rußheim is mostly done now, only some streets are missing. Track: @flschm/traces/82310

Been tidying up the horrendous rendition of the Garden State Parkway in new Jersey, so far only got as far as Exit 130 (US 1). Previous rendition gave the Parkway too few carriageways north of the Raritan River and was set too low of a highway classification southward.

The town of Hessle in East Yorkshire, UK has had a first pass completed. There's always more to add, especially detail of shops, but streets are mapped and named and main amenities added.
