Re: [Talk-ca] Building Import update

John Oui, je suggère  à ceux qui préparent un plan d'importation, de modifier la donnée avant l'importation. Des critères comme ceux que j'ai présenté pourraient être utilisés dans un script pour simplifier les polygones qui sont quasi orthogonaux. Pour simplifier la procédue d'import, deux

Re: [Talk-ca] Building Import update

I accept the nicest way is to check the data beforehand. Scripting it is fairly simple. Are you suggesting a two stage process of take the data and run the script first then task manager the data to be imported to manually correct the data? My eyesight isn't good enough to pick out none right

[Talk-ca] Some feedback on import quality in Toronto

Hi all, I had a chance this morning to work on cleaning up some of the already-imported data in Toronto. I wanted to be a little methodical about this, so I picked a single typical block near where I live. All the building data on this block came from the import and I did everything in one

Re: [Talk-ca] Some feedback on import quality in Toronto

My expectation was that the import would be based on the city's records of foundations for the buildings. I would not expect to see sheds etc.and I'd be quite happy to only get most of the buildings. The rest can be added by local mappers at a later date. My expectation is they will be

Re: [Talk-ca] Some feedback on import quality in Toronto

John, You seem to be mostly addressing topics which have been brought up elsewhere. My email was meant to address specific data quality issues in Toronto, so I'm not sure how to respond to all of this. To your broader question though, my position is that we *do* have the volunteers and

Re: [Talk-ca] Some feedback on import quality in Toronto

So I suggest that you name yourself as the coordinator on the wiki page for Toronto that allows the local mappers in Toronto to import at the rate and to the standard you suggest. For the rest of the country the data is licensed to be acceptable to OpenStreetMap thus anyone can set up their own

Re: [Talk-ca] Some feedback on import quality in Toronto

Mmm, careful with your language, John. The data "have a license which is compatible with OSM's ODbL" (is an accurate way to say it). I believe that took about eight years and was a difficult slog, a lot of hard work by many, lessons learned from Ottawa, a determination by OSM's LWG, but it is

Re: [Talk-ca] Building Import update

De tes exemples sortis du chapeau ne font pas avancer la discussion. J'attends la démonstration de John que les données d'import pour Ottawa représentent bien le contour des bâtiments et sont des données de qualité.   Pierre Le dimanche 3 février 2019 12 h 07 min 55 s HNE, john whelan

Re: [Talk-ca] Building Import update

Pierre writes that he is "waiting for John's demonstration that the import data for Ottawa represents the outline of the buildings and is quality data." In reality, anybody (not necessarily John) can offer this sort of characterization. En réalité, n'importe qui (pas nécessairement John) peut

The Ottawa building outline import was done by the local Ottawa mappers to a standard they were happy with. Cheerio John On Sun, 3 Feb 2019 at 14:42, Pierre Béland wrote: > De tes exemples sortis du chapeau ne font pas avancer la discussion. > > J'attends la démonstration de John que les

Re: [Talk-ca] Building Import update

Le «acid test» de John, avec une architecture aussi irrégulière, a abimé les «Bay Windows» et l'eau fuit de partout tout comme son analyse basée sur Orléans à l'extérieur de la zone étudiée ! Une analyse plus approfondie de la zone du centre-ville nous montre qu'il y a peu de telles

Re: [Talk-ca] Building Import update

So you're proposing that a script is run to correct minor deviations in the remaining data which sounds a reasonable approach to me and would improve data quality. So run the data through the script. Then import and run overpass to pick out those that need manual adjustment? If we do this

Re: [Talk-ca] Building Import update

Je suggère oui, d'abord le script avec 2 fichiers d'output parce qu'ensuite il sera beaucoup plus simple d'importer les données déja corrigées. Sinon une variable pour distinguer les deux et risque de l'importer dans OSM ? Et je pense à un autre aspect. Le script pourrait s'assurer qu'il n'y a

Re: [Talk-ca] Building Import update

I'm hearing we keep the single import project as such. I'm hearing that we should preprocess the data first splitting out outlines that meet Pierre's right angle checks. This data can just be imported using the current processes. I'm hearing we should then run the correcting scripts and extract

Re: [Talk-ca] Building Import update

I dislike sounding simply "like a cheerleader," here however, I am deeply encouraged by what I see as substantial progress. This sort of discussion bodes very well for the future of the import. Keep up the good work! SteveA On Feb 3, 2019, at 3:26 PM, john whelan wrote: > I'm hearing we

Having reviewed the changeset, here are my 2 cents. OsmCha link for reference: https://osmcha.mapbox.com/changesets/66881357/ 1) IMO squaring is not needed in most of those cases. - You can see difference between square and non-square ONLY at high zoom level. And even then, it's not visible to

Re: [Talk-ca] Building Import update

I'm not hearing we have a clear consensus on modifying the shape of buildings with scripts and the Q button. My own personal view is it could introduce errors and unless it is very obviously wrong when it should get picked up by the importing mapper it should be left as is. Cheerio John On Sun,

Re: [Talk-ca] Some feedback on import quality in Toronto

I largely agree with Yaro, but will say 1) It is possible to square almost square angles with JOSM - it has an informational warning in validation, and automatically squares the angle by slightly moving the offending node. This fix doesn't ruin the geometry of the building, as pressing Q so often

Re: [Talk-ca] Some feedback on import quality in Toronto

It is an honor to participate in this good growth. May good (province-at-a-time building) data enter OSM at the hands of skilled OSM editors who have good instructions on "how" (the Import Plan can go that distance, please finish it) as their skills of good editing OSM data push the import
