We have already fairly accurately defined the provinces and counties using relations (a collection of ways).

See here

The Ulster relation is defined with admin_level=5, while the ulster/connaught nodes are tagged as place=region.

From a look at Nominatim docs both province node and relation have the same rank of 10.

I don't know why Nominatim is preferring the region node rather than the province relation.

In the end, I've deleted the province place=region nodes as the province relations explicitly define the extent.

Lets see what Nominatim reports in 2-3 days...

The correct thing for a set of nodes is a Voronoi diagram. So Nominatim probably either uses that or a fast approximation to it.

IrlJidel · 12-07-2010 9:33am

So looks like Killybegs no longer reports itself in Connacht or any province for that matter.

I also suspect that the fact that Ulster spans two countries isn't a case well handled by Nominatim

These nominatim node 'polygons' are not stored or defined in OSM. They are generated using an algorothm where it looks for any is_in tags (amongst others) and the proximity to other features at the same level. They are a rough approximation.

To get better polygons you can either 1) create admin_level boundaries defining the boundary of the town/village etc or 2) add is_in tags

OSM is free form - you can tag things as you like and invent your own tags.
Only common tags get rendered on openstreetmap.org. Anyone has access to the raw data so we can configure our own server at http://maps.openstreetmap.ie to render these.

I know exchanges aren't usually sign posted or published but I don't think it is illegial to map these but you should check that out.

Looks like someone has made a map of exchanges:

Exchanges are considered as possible terrorist targets as they are a key part of essential infrastrucure so are not widely advertised or signed.

People/companies love spreading FUD about something being "private" and thus illegal to map. Do not be fooled though. It may not be allowed to go in and survey... but why would the fact that something belongs to a private company/individual make it illegal to map?

Mapquest/AOL are now using OSM data!

http://blogs.wsj.com/digits/2010/07/09/aols-mapquest-looks-to-wikipedia-model-for-mapping/

You can view it here: http://open.mapquest.co.uk/

Their site also offers driving directions using osm data.

Ireland still has a long way to go to be road complete, but it is some vindication of how mainstream OSM can become.

They are also allocating $1m for improving the US maps on OSM.

$1m

You and your British numbering system... "m" stands for milli in the SI system. "M" is mega.

I think it is more for building mapping communities in the US.

http://corp.aol.com/2010/07/09/mapquest-opens-up-in-europe-with-open-source-mapping-with-uk-l/

"Investing in Open-Source Mapping
Additionally, AOL today announced a $1 million fund to support the growth of open-source mapping in the United States.

The new fund will support projects in specific communities over the next year to help expand and enhance the geographic data available to developers, designers and other users as part of AOL's commitment to open-source technology."

...

"AOL's $1 million grant will help fund local initiatives to identify and plug gaps in information in open-source mapping data about specific U.S. communities covered by Patch. Patch offers news, business listings, recreation, events and other information in communities across America. The Patch network currently covers communities in California, Connecticut, Massachusetts, New Jersey and New York, with new sites constantly coming online."

Discovered http://weait.com/content/openstreetmap-beginner as a handy stepping stone for the beginner. Thought I should mention it ;-)

Someone has mapped a whole pile of bogs around the midlands and a load of Bord na Monas railways

radagast · 02-08-2010 11:13pm

I wonder who that could've been?

I downloaded the following app for my iPhone today:

Can I use it to contribute to the OSM project? It was very accurate up to a point - but if I ask it to guide me from my home in Tipp to my home in Ballincollig, it firstly sends me via Cork city rather than the SRR and N22 Ballincollig Bypass, and it's missing the name of my apartment complex.

radagast · 06-11-2011 2:51am

From what I understand the skobbler navigation app doesn't have the facilities to create tracks/logs for adding roads and such (motorways etc) that might not yet be added, and so influencing the algorithm used to suggest that incorrect route, or for adding [names of] POIs; as you did mention that the name of your apartment complex is wrong.

You could use the openstreetbugs site or skobbler's mapdust site to register "bugs" in the site that other openstreetmap contributors use to see if there's anything else they need to do to improve the map data.

I don't have an iphone myself so I can't make a personal recommendation from my own experience, but after having a look at http://wiki.openstreetmap.org/wiki/IPhone#Track_making_features it seems the Track'n Trail app might be the best option of the lot for making tracks. For editing POIs it seems ILOE fits the bill.

Hopefully I've been of some help

Amtmann · 06-11-2011 11:29am

Good info. Unfortunately, Trank'n Trail isn't available in the Ireland app store. It's a pity because I have some free time today and could map some roads in the locality that are missing from OSM.

jmkennedyie · 06-11-2011 2:06pm

You can also improve OpenStreetMaps by using your PC: use the web-based Potlatch2 or the client-based JOSM editor to trace over Bing (or other) satellite images. You may need to configure an offset inside the editor to perfectly align the sat image with the existing roads etc. in the map.

They take a bit of getting used to, but are very powerful. I have not tried Potlatch2, JOSM did everything I needed and more. Very powerful editor.

Tremelo,

Check out Motion-X GPS app for iPhone. It lets you save tracks, export them as GPX (via email), which you can then import to JOSM and trace over.

Amtmann · 06-11-2011 5:08pm

Looks like a great app, csd. There's a record tracks option, which I presume I can use to record the coordinates and routes of various roads. Sounds like it will do the job very nicely. I'll test it out an several unmapped local roads in two weeks' time and then try to upload them to OSM. I must say, though, that I'm finding the integrated OSM editor quite complex to use.

nordydan · 08-11-2011 12:28pm

I find OSMAnd a great Android app when I'm on holidays. I used it earlier this year to find our hotel through winding streets when we were at a wedding in Italy. Heading to Berlin in a few weeks, got the map downloaded already. Happy days
