I've noticed that the use of identical boundary relations may cause display issue, witness 95672 and 95671. The first is a postal code (at
administrative_level=8 for some reason) with
name=3060. The other is the suburb (
The result is that depending on zoom the displayed name will alternate between "Fawkner" and "3060". Surely there is no need to list
name=3060?, and arguably a single relation could be done to cover both? Also I might be crazy but are postal code realy independent administrative units in need of their own boundary definitions?
You can't delete entries anymore. What the crap? I could swear it used to be possible.
...and downloaded JOSM. So far I'm finding it a bit on the meh side. I'm using it primarily to add relations to the RTC network and a few other tasks (turning multiple-node intersection in a single one is a doozie with Merge node). Mostly I find it unintuitive and slightly overcrowded, and having to download the data constantly because you're running out of the original area is annoying, plus it does some simple tasks (primarily moving on the map) in ways radically different from Potlatch, and some tasks you would think would be simplified by it (why isn't there a "Duplicate relation" tool??) are barely so.
After a dearth of enthusiasm, I got off my lazy ass and did all missing slices in the northern half of my one-man cake.
At this stage, the only thing missing are the bus stops (which usually require to acquire a fairly large amount of data each, so I haven't done much with them yet).
-Slice H is going to undergo fairly major revision at some point in the future if a project to construct condos on the 1800 René-Lévesque lot goes through. That building used to face a street that no longer exists, hence why its entrance is on Joseph-Manceau, and the façade toward the highway. Otherwise its only odd feature is that Canada Post says there is a 1055 civic number on Saint-Matthieu, which I have not found, and also that there are no addresses actually located on Joseph-Manseau street. While looking for stuff, I also learned that the formal name of the jardin des Sculptures is "Esplanade Ernest-Cormier"
-Slice I was... interesting. It's got some pretty tightly packed up addresses, what looks like a private park-like thing (which is actually public access AFAICT. It's misleading because I do not map much urban furniture), and a missing street (Amesbury Avenue). Many postcode-owning buildings too. There's a weird dirt road going off behind the SPVM's Southern Logistic center, with a purported "920, Guy" CP address marked, but it's not recognized by Canada Post.
-Slice G had a lot of boring residential house numbering, but the alleyways were sometimes difficult to transfer from my notes to the map.
-Slice C, which I had expected to be by far the hardest, turned out to be easy EXCEPT where the alleys (part of which actually ran as a tunnel through Complexe Du Fort), which were a proper nightmare to map and transfer on data. You'll notice a small
highway=path segment. This is because although the pavement is continuous, this is a small space between the corners of two buildings where a normal motorized vehicle would certainly not fit.
My slice E turned to contain not one, but two missing streets, it also had some idiosyncratic street numbering on Prospect Street and Weredale Park (whose name I'm not clear whether it includes "Street" or not).
There was also an odd footpath extend from the corner of Prospect. It took me a while to figure out that it did not extend to Weredale Park (at first I thought it was the same as this footpath), but it in fact, does not even connect directly to the alleyway behind Clandeboye Avenue, but to the Weredale House parking lot. Also found a few permissive access shortcuts.
What this really outlined for me is that Westmount street names will be thoroughly frustrating to edit because they must be entered billingually and it is not entirely obvious whether the basic name should be French or English. Also, the street name indications on the ground do not include the "street"/"avenue"/etc. specific. AFAICT, most of the North-South (or rather NW-SE) streets are "Avenue" and the E-W (SW-NE) are "Streets, with various other oddly placed ways having other names (e.g. "Road", "circle", "crescent", there is even one called just "The Boulevard"). I've changed a few, but I'm not clear whether I should change the matching addresses too. This is really frustrating (though the street name on the envelope does not matter in the end: any addressing method is valid anyway, and you can generally leave out the part that changes anyway!).
I just spent a while taking in, then entering data for my slice F. It was rather simple, except for a lot of fumbling around the first, which eventually led me to abandon the first attempt altogether.
Lotsa one-way fixes here. Turns out Tupper is one-way Waster from Gladstone to Atwater, two from Atwater to Du Fort, one-way eastward from there to Saint-Marc, and westward AGAIN thence to its end. Similarly Baile was one-way eastward, not westward, as previously entered between Du Fort and Saint-Marc (I forgot to check whether the segment from Saint-Marc to Saint-Mathieu was also one-way. Bad Circeus, bad!).
Overall the addressing was refreshingly easy to jot down and mapped easily into post codes, except where Place Dufort had four of them, and Post Canada sometimes list addresses with separate post codes (such as Place Saint-Marc and the H Post Office) as part of address ranges sharing post codes.
Also got to enter three turn restrictions, including the one from Atwater to Dorchester. Forgot AGAIN to make Tupper just
highway=residential instead of
Slice D was a <sarcasm>bundle of joy</sarcasm> to do. Complicated and messy with really weird post code and house numbers mapping.
-4039 appears to cover at least two separate buildings. It is recorded by Canada Post as "Reddy Memorial Hospital", but that seems to have closed years ago.
-4150 Sainte-Catherine has three associated postcodes!
-4020 and 4030 Tupper are apparently delivery docks for 4010, but do not share the postcode.
-The Atwater Library (a privately funded public library) and a branch of the Montreal Children's Library share the same building, but this is obfuscated because the addresses are on different streets.
-I really wonder why 4000 Sainte-Catherine (a small Asian fusion restaurant) has a separate postcode...
-Despite my mapping, there is no car (foot is okay) access between the Staples parking and the alley behind.
I am still rather frustrated with the difficulty of mapping in a fashion that makes relatively clear where on can circulate on foot. I decided not to apply any brute force edits anymore. It just makes a MESS of the render. Yes I know "Do not map for the render blah blah", but remember that data that no tool render/uses in a pertinent fashion might as well not exist as far as users are concerned.
I have a few uncertainty over these edits:
-I tagged the area surrounding the Canadian Centre For Architecture as
landuse=grass.* It's not a municipal park, but clearly private land where the paths should be tagged with
access=permissive when someone gets to it.
-I have two places where I need the ability to have two
name= tags, because quite honestly I'm not going to start mapping buildings just to fix that. The issue are large apartment buildings with postal names and separate post codes (Sussex House and The Alden) which happen to have a
shop=convenience in the lobby (named respectively Dépanneur Le Rochefort 88 and Dépanneur Hap Tak)
*I think I'm going to start using
landuse=grass as my "default" tag for what I refer to as "institutional" landuse: the lands of convents, monasteries, large churchyards and public buildings, estates etc. that are sometimes nearly, but not entirely public access, and definitely not parks or commons, but frequently look like them. I'm not sure when I'll get to add
landuse to the entire area around my home, though.
Walking Papers is neat, but at the moment it is useless if you want to edit on the main part of Montreal Island or in Longueuil. Earlier this month, y'see, there was a screw up with some data that shifted several dozen points on the south shore, this has since been fixed in most mirrors, but Walking papers is nearly a week late, resulting in that mess making it impossible for me to use the service for my area (I just moved. If I still lived in Montréal-Est, that wouldn't be a problem).
The Cloudmade "minutely" upgraded no-name layers has devolved into an utterly useless farce. In someone else's words: "The minutely noname tile server is currently even more outdated than the weekly one."
The osm History Viewer is an awesome little tool that is very poorly documented. One has to make educated guesses at what the colors mean to get anything useful out of it.
I'm mapping again in my new neighborhood. It's crazy the sketchiness of the place! I feel like a little child again! I discovered that the Moroccan consulate is two street corners from my home! Any Montrealers interested in some cake slice sharing?
I've been wondering how to tag the area colloquially known as the Champ d'Hydro, near my old home.
It's basically an mix of fields, a ravine, and small, young groves kept clear due to the electric high-tension line. Trees over a given height are razed down every few years by Hydro Québec.
It's not quite any of
natural=scree (it has ravines and very sandy/rocky soil), though it has some features of them all, and definitely not a
landuse=field (mildly confusing, apparently it's for farm field, it's rendered, but undocumented on the wiki),
In fact, I'm not entirely sure whether this is
There's one thing that came to me regarding the People's Map gorgeous (but unavailable to us) imagery. Basically, the principle is simple: you can't use it to map directly, but you definitely can use it to spot missing things. So basically what I'm doing is looking at the close-level imagery to spot missing streets or footpaths, and then entering OpenStreetBugs for people to map them (Yes I know, I should map them myself, but I live in Montreal, so that wouldn't be very practical :p).
I just found a weird overlap between this (a trace?) and the three separate segments from the tiger data that forms NY 17. There also seems to be some oddball overlapping in the area of the NY 17/US 6/I-87 interchange...
I just came across this oddly located highway=motorway. Anybody got any idea why the frick it's tagged that way?
EDIT: Quick examination of the satellite image reveals it to apparently be some sort of slip or gravel road.
Fixed a node where, for some reason, a footpath ended at the Montreal Blue Line, causing a nonsensical level crossing to be rendered in Osmarender. Also took the occasion to combine the end of the path and the subway entrance.
So, I noticed the housenumbers have been modified alongside their showing up in Mapnik. The new numbers are a significant improvement on the previous ones, but I gotta say I think Mapnik does it much better by making it secondary to most other features.
Although I appreciate the new Osmarender playground icon, I'm mildly irritated that it will show up for both a node and an area when you put one or several of the latters in the former...
Made a small adjustment to the Eastern edge of UDM campus. The former Convent of the Sisters of the Holy Names of Jesus and Mary, sold to UDM in 2003 and renamed "Pavillon 1420 Boulevard Mont-Royal", was recently re-sold to a promoter who is to convert the building into apartments. Fortunately the city materials (there was a public consultation because the building is located in a historic district) include maps that allow to trace a pretty accurate map of the lot.
Matching postal codes to delivery boxes has been far easier so far than I had expected (south of Fauna Street, anyway), except that it turns out from this I have utterly messed up when I originally noted the names of Émilois Street (formerly Giroux Street) and Françoise-Giffard Street (Formerly Laurentian Street). I have now fixed that.
My original memory--which puts Giroux (and not Laurentian) intersecting with Lapierre--and not the maps, were accurate, Canada Post's database currently puts these addresses firmly on Émilois Street.
On the way, I noticed no less than three mail boxes I had overlooked: one on Beading Street (amusing fact: despite this, and that there are car entrances on the street, no addresses are actually located on Beading Street!), one on Lafond Street, and a second one on the Fréchette Street frontage of Beauséjour Park (that last one did not exist in my memories!).
I also came across the SAME employee at the Beading street mailbox XD. Only one last anomalous thing is that CP gives a G3E2H4 code for a segment of White Poplars Street, which makes no sense in any case: there is no room for an extra box (I have now walked the whole street! Twice!) and there is NO reason for it to be a G3E 2** postal code there!
Went ahead as I was planning and surveyed the location of all community mailboxes, which simultaneously act as letter- and postboxes. I have the locations for (AFAIK) all of those west of Fréchette Street (north of Fauna Street) and Lapierre Street (south of Fauna Street, but not farther south than the Françoise Giffard Street intersection). I also mapped in a very rough fashion the unmapped street segments located north of the Grey Pines and Alliance Street intersection. Ironically enough, I came across a postal employee busy at this one right as I was finishing my run.
As a side note, it was a nice occasion of surveying some of the nice architecture in the area. Spotted some old houses, but also was dismayed at the overwhelming march of vinyl, which is replacing the older-style wooden sidings and destroying much of the personality of many buildings. I was also suprised to find out the northern segment of Fréchette Street is entirely devoid of boxes, as appears to be Lapierre and Fauna streets. I wonder if they are serviced by the boxes on adjacent streets or at the post office...
I'll also have a try at using the Canada Post address-to-postal code widget to see if I can match the boxes to specific LDUs within the G3E FSA that covers Saint-Émile, though I'm doubtful as to the chances of success...
Do you think that tag for the local junkyard would be appropriate? I don't think landuse=landfill would beokay,a s tempting as it is. For the time being, it's twin tagged with landuse=industrial.
And instead of complaining to myself about being bored or some areas not getting filled, I went ahead and traced a bunch of stuff in the Neufchatel area of Quebec City. Didn't add any street names, but did name a parc or two. Oddly enough, the parc at Charles-Auguste-Savard Community Center is given as "Savard Park" in several places, although the city website clearly identifies on a list of skating rinks as "Saint-André Park" (which is also the name I'd been assuming for it). For some oddball reason, the labels for Saint-André branch library and L'Escabelle schoolground show up twice in Osmarender...
I've also taken to map more land use. There are annoying holes that show up around community buildings and whatnots. I'm not clear whether to leave those off or add a landuse="institutional" or something like that (or simply shove them in residential). Furthermore, mapping landuses in areas that have a lot of small shops and stuff in an otherwise overwhelmingly residential area is giving me a headache. I probably COULD just break up the Saint-Émile core in four (virtually all shops and office are on de La Faune or Lapierre) and do away with a nasty multipolygon, but that would be overkill IMHO. However, without multipolygons, we get areas that are technically tagged simultaneously as residential and retail/commercial(I wish we just used "commercial". Separating those two tends to be a PAIN)/industrial. And there are still a number of shops/offices/parkings etc etc. that are not in the relation, cf. the Caisse Populaire, the community center and the local fast food joint. I'm seriously starting to think I should have kept to my primary interpretation of "landuse as very predominantly X". Or at least request a landuse=mixed tag ARGH.
