Heute habe ich begonnen Hausnummern in Erlabrunn einzutragen. Einige Straßen besonders im südlichen Teil sind schon vollständig. Dass an manchen Häusern keine Hausnummer angegeben ist, macht das ganze nicht gerade einfacher. Zweimal habe ich die Hausnummern nur interpoliert, da eine exakte Integration keinerlei Vorteile in punkto Genauigkeit gebracht hätte.

Gleichzeitig habe ich auch gleich ein paar andere Änderungen gemacht. So habe ich Fußwege korrigiert bzw integriert, ein Cafe zum Restaurant aufgewertet, einen Spielplatz eingefügt und zwei kurze tracks gemappt.

PS. Habe nun die Brücken der Umgehungsstraße geändert, besser gesagt, die Formatierung der Tunnel darunter.

After seeing someone using Merkaartor to edit in OSM, I decided to give it a try last night. Before this, I've been exclusively using Potlatch. Potlatch is a pretty good application and is definitely the best Flash application I've ever seen but I quickly ran into one of its limitations while I was doing Eastwood City and Bonifacio High Street (in Metro Manila, Philippines). The limitation is that at the highest zoom level, you cannot place nodes more accurately: the nodes snap to a 3-pixel "grid". This 3-pixel grid translates to a resolution of almost 3 feet at the latitude I'm working at. This is more than good enough for roads, but not adequate for buildings. (I'm kinda OC ["obsessive-compulsive", slang in Philippine English] when mapping the details of buildings, and this limitation prevented me from making nice right angles of small idented corners of buildings. See this view of Bonifacio High Street for an example of non-perpendicular corners. I find this lack of right angles maddening! :-P) I asked Richard, Potlatch's creator, about it and he acknowledged this limitation (our conversation is at the OSM Wiki).

If you're using Potlatch, then Merkaartor gets some getting used to with regards to its interface. The workflow is pretty much the same as in JOSM: you go to an area, download the data, edit at will, then upload the changes. I like it because it doesn't have the aforementioned 3-pixel limitation, and in addition, it blows up the Yahoo! map tiles if they're not available in a higher zoom level; Potlatch just shows Yahoo!'s "We're sorry, the data you have requested is unavailable" tiles. (I'm not sure if Merkaartor's behavior is allowed by Yahoo!'s TOS).

I'll still continue to use Potlatch as a general editing tool since it's pretty quick and I'm used to it. I'll just bring out Merkaartor if ever I want some finely wrought detail. :-)

(This is also cross-posted, with some changes, to the talk-ph mailing list.)

I have finally got around to uploading some data and contributing to OSM. The last few years have been hectic with a few children being added to the family and attempting to complete my masters degree. Now that the masters has been handed in I have some free time.
I have added some of the back roads between Lake Boga & Kerang (Australia). These will be added to reasonably regularly. I have also updated the Loddon Valley Highway from my GPS track (Trimble GeoXH). In time I hope to add to/update streets in and around Bendigo (home).
Are there any other OSM users from Bendigo?
Happy editing!

So, after browsing this site for the last couple of months, I have finally managed to join in the fun and contribute! Admittedly it's only a small contribution to start with, as I have no GPS receiver as yet to provide and large-scale additions, but I can use some local knowledge to make additions that I can be sure are accurate enough - such as this addition to the junction of Church View Road and Wyattville Road in Ballybrack (and the addition of the name of Church View Road). I'm still getting used to JOSM at the moment, so this alone took me the best part of two hours! Nevertheless, I'm hopeful that I might be able to make more meaningful contributions without taking up much time in the future!

Today I tried to tidy up a few missing names in the City of London. I came to this small street: which has no street sign. There are businesses on the street but nobody working there knew what the street was called! I've asked the Corporation of London to fix the missing sign, so I hope to find out the name.

I tried Googling for the two adjoining streets (Queen Street and Pancras Lane) to see if there was some web page describing what this street is called. I didn't find anything, but I did discover that between Pancras Lane and Cheapside is the former Gropecunt Lane, where the medieval Londoner could find whores. It is a shame that historical or obsolete streets cannot be added to OSM (a map will sometimes give the former name of an existing road, but here the whole street has disappeared).

If it turns out the street I found is truly unnamed, I will know what to suggest.

I'm getting annoyed with the difficulty of representing actual pedestrian movement on the map.

Here's an example I'm familiar with: According to standard routing software, the shortest way on foot between Réal-Cloutier Park, Saint-Émile and Beading Street is a convoluted circulation through either Laurentian Street or via a purported footpath, which is properly part of the "right of way" bordering a parking and leading to a single house and an entrance to the park (hence why I've re-tagged it as highway=service). In practice, the quickest way is obviously walking through Beauséjour School Playground.

Unfortunately, there is no actual ways to tell the software that this is possible. Not to mention that the park is fenced, and I had to move it away from Fréchette street because otherwise the community postbox there would be in the park according to the map. How to tell the software that you can walk from Lapierre and Welcome Street to the entrance, and from the other entrance to Fréchette?

None of the options feel like anything more than a hack: marking a footpath or service way would be both inaccurate and overdetailed, and adding the school parking as an area would be misleading (it's not public access, although the adjoining church parking is a designated park and ride) and not necessarily recognized by routing software. And even if any of these options were implemented, there is no guarantee whatsoever the software will detect the possibiliy of going through the playground.

*wheezes a bit* That was a fingerful to type.

I'm like a child playing with batteries, cables and light bulbs. (What, you didn't play with these as a child? ;-) )
Only that it's now with virtual power plants and lines in OSM. :-)
For example, I'm happy that the city of Esslingen now has electric power in OSM since I filled the last gap between it and the nearby coal power plant:
osm.org/?lat=48.7146&lon=9.3488&zoom=14&layers=B000FTF
Next big milestone will be to complete the long line which (among other areas) supplies the city of Göppingen where I was born.
It's the one that runs to the West in this map:
osm.org/?lat=48.6992&lon=9.5229&zoom=14&layers=B000FTF
(Yes I know that the lines are redundant and that the power doesn't simply come from one specific plant. :-) )

On the talk-ca list, we have lots of great discussion going on. You can go through it if you like...

One idea that i'm floating is this:

Import all the Data which is available as NODES
each of these nodes would have the attributes of the broken down polygons, and lines, and different points.

This would essentially make it a 'connect-the-dots' game, for areas which already have OSM data.

This way, when updates of government data is available, just nodes get imported.

These nodes wont get rendered, as they contain tags that renders do not understand.

Once the Canadian Node import is done, then the different map features (Points / Lines / Areas) can be imported, starting with tiles that don't have any OSM data.
Then when we get to tiles that have just a bit of road data, we can import everything BUT the roads.. and leave it to the local area mappers to 'connect-the-dots'
then when in even more complete areas are ready to take the import, the mappers can be selective as to what they like to import, and the rest, and be made by connecting the dots.

Does anyone have any feedback on this idea?

Thanks,
Sam

P.S. im working on the CanVec chart which has 11 themes with 90 different entities. The rest of it should be available from the GeoBase download set.
osm.wiki/CanVec_OSM_Map_Features

edit: Just nodes (All GeoBase/CanVec) to get imported for the 10 most complete tiles
For the 10-100 partially mapped tiles, everything but the roads would get imported, and the roads would get imported as nodes only
For all the other tiles: everything gets imported.
For updates: only nodes gets imported.
Coastline (thats already in OSM) would not be imported, (that is only a section of the NHN) the rivers/marsh etc. would all get imported.

While I have until further noticed stopped cleaning up complex intersection, the one at what is now Louis-XIV and Bourg-Royal, in Charlesbourgh, was just ridiculous.

For the record, what we have (or rather had, given I simplified it), was two streets briefly becoming grade-separated at the intersection. The result:
-Is visually indistinct and confusing both in viewing and editing mode, hence
-Is almost impossible to edit
-Gives little to no advantages regarding e.g. routing
-Is, although laudably accurate, ridiculously too detailed IMHO

It admittedly doesn't help that I needed to run a bus route that turns at this intersection.

And while we're at it, here's a stumper for ya: how would you indicate that the route does not cross itself over, but in fact makes two right angle turn at this intersection? I've rendered it with four separate segments instead of two for the time being, but I'm curious...
