Re: [Talk-ca] broken forests in eastern Canada

[Alan Richards]

I believe these are the result of importing Canvec landuse data for some
areas and not for others. Because the data is in square chunks, you end up
with these unnatural looking squares on the map. Really it's just a case of
the other areas don't have detail yet.

Across the border it looks like the US just has parks and national forests,
etc. mapped, and not the general natural=forest that you see across Canada.

[Talk-ca] broken forests in eastern Canada

[Antoine Beaupré]

hi everyone (allo tout le monde!!)

one of the most frustrating experiences I have with Openstreetmap in
Canada is this ugly forest display:

http://www.openstreetmap.org/#map=8/45.227/-73.916

Just compare how the forests and parks are mapped between the US and
Canada. On our side of the border, you got huge chunks of square forests
that definitely do not reflect the current reality, whereas down south
you clearly see national parks, forests and no weird square things.

I don't really understand how this happened, but it's been there a long
time. I feel it's some Canvec import that went wrong, but it's been
there for so long that it seems people just forgot about it or moved on.

I looked around in the .qc and .ca wiki pages and couldn't find anything
about it, so I figured I would bring that up here (again?).

Are there any plans to fix this? How would one go around fixing this
anyways?

In particular, I'm curious to hear if people would know how to import
*all* the park limits in Québec. It seems those are better mapped in
Ontario, and I can't imagine those wore drawn by hand..

Thanks for any feedback (and please CC me, I'm not on the list).

A.

Re: [Talk-ca] Crowdsourcing buildings - project with StatCan

[Ellefsen, Bjenk (STATCAN)]

Pierre, oui je connais bien MBTiles. J’ai déjà travaillé avec ça pour un projet.

Je produisais mes tuiles pour le Canada sur un vieux MacBook Pro avec TileMill. 
Je laissais rouler la nuit, tout un plaisir le matin de trouver qu’il y avait 
une erreur.
Good times !

Je vais regarder Overpass à tête reposée ce weekend et jouer un peu avec 
osmlint.

Merci beaucoup, Pierre je t’en redonne des nouvelles !

Je n'ai pas utilisé OSMLint. Ce sont de nouveaux produits de contrôle de 
qualité en développement par MapBox.

Pour une petite zone telle que Gatineau-Ottawa, des requêtes Overpass offrent 
beaucoup de flexibilité pour l'analyse qualité, les statistiques et le suivi 
des contributeurs. On peut sélectionner des couches particuilères telles que 
immeubles, adresses, etc.

Les outils tels que OSMLint sont aussi intéressants mais demandent davantage de 
développement.

Avec OSMLint, on sélectionne une zone BBOX, et les données sont produites sous 
forme de tuiles MBTiles pour visualisation de cartes avec outils OpenLayers ou 
Leaflet.

On utilise la même technologie que pour les images 256 x 256 pixels utilisés 
sur les cartes. Les tuiles sont produites pour différents niveaux de zoom Un 
fichier MBTiles est un fichier SQLite et des procédures permettent de lire ces 
fichiers dans OpenLayers ou Leaflet, de sélectionner les données pour le niveau 
de zoom et la zone sélectionnée.

Ce format permet de produire une couche de données et de visualiser sur une 
carte un grand nombre de données, comme l'exemple sur cette page :
Data quality + vandalism detection in 
OpenStreetMap

Pierre,

Ces scripts sont intéressants. Je vais regarder ça de plus près.

As-tu essayer osmlint? Tu as une opinion sur cet outil?

Bonjour Bjenk

Le script python suivant permet d'obtenir des statistiques de contribution pour 
une zone rectangulaire - BBOX.
https://github.com/pierzen/osm-contributor-stats
Pour chaque Changeset OSM, il retourne le uid de l'usager plus stats de 
modification des objets.  Il fonctionne relativement bien pour une petite zone. 
Mais lorsque les serveurs OSM sont surchargés comme actuellement, il y a 
souvent des interruptions, et les données ne sont pas toutes transférées.

Une solution simple est de lancer régulièrement le script Overpass suivant et 
de simplement modifier la date Newer: (objets modifiés depuis date Newer). On 
peut voir visuellement où il y a eu des modifications depuis date donnée. On 
peut aussi importer dans JOSM ou encore importer les données pour analyse à 
l'aide d'un XML-Parser.

Hello,

I wish to share with you what we are planning on doing to track progress and 
monitor:

Baseline: we will do an extract of OSM before launch. We will take note of the 
number of buildings in Ottawa/Gatineau, number of users, number of tags per 
building.
Periodically, we will monitor for change in number of buildings, tags per 
buildings and number of users and their contributions.

Any good reference on what can be done for analysis or users contributions? I 
know Mikel presented something at SOTM US and I am trying to track that down.

Mikel Maron suggested osmlint. If anyone else has suggestions, insights for the 
methodology and tools, indicators, please don’t hesitate!

Re: [Talk-ca] JOSM: purge import pictures into sequence after use

[Laura O'Grady]

Hi Stewart,

Thanks for your response.

I'm not sure if I had a layer for this. I will check next time I use this 
option. Excellent suggestion. Can't believe I didn't think of that.

Re: which plugin - that's a good question. I didn't include that detail as I'm 
not sure. I have more than one photo-related one installed. I was hoping 
someone would recognize which one by my comments.

I now think it is this one by Mapillary:

http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Mapillary

Details about using the "import into sequence after use" feature are not 
provided in the wiki entry linked above.

I was able to solve it by rebooting. This is obviously not a long term 
solution. 

However, according to the info at the link I need to click on the image(s) and 
delete. Kind of tedious when you have 50 + but I guess it's better than 
rebooting.

Laura

Re: [Talk-ca] Prince Edward County - Sandbanks.

Should be fixed now and the OSM geocoding of "West Lake, Prince Edward
County
"
works as well.

Re: [Talk-ca] Prince Edward County - Sandbanks.

[Denis Carriere]

Hey Greg,

Dealing with complex relations can be a hard task, I've started cleaning up
the area and I'm going to add West Lake after I'm finished.

I will still keep the same geometry for Lake Ontario except add an
additional relation for West Lake.

Thanks for the OSM notification! :)

Hi Laura,

In the Layers pane, select and delete the "Geotagged Images" layer
between image imports, perhaps?

What plugin are you using to get the "import pictures into sequence"
File menu entry? I don't see it, but got the same effect by opening
images directly via File → Open …

Greetings.  Please forgive me if this is the wrong list.  
West Lake in Prince Edward Country (ON) is not identified as such, rather, it 
is labelled “Lake Ontario”.  I would rename it except that the body of water is 
connected to Lake Ontario at Wellington through the canal located there (the 
satellite imagery doesn’t quite match the lake boundary either).  I gather I 
need to split the polygon, but I am not familiar on doing so, and I don’t want 
to mess up all of Lake Ontario if I try.
I did name “East Lake” (previously un-named).  However, the polygon includes 
the “Outlet River” which drains the East Lake into Lake Ontario, so it too 
needs splitting.

Thanks.
