Re: [Talk-ca] OSM CanVec.
I thought the whole idea of importing was to just automate loading data. Then it can be cleaned up on the map. If you are suggesting manual intervention by the importer by checking against satellite and other images aren't you defeating the purpose? Cheerio John Looks good, much better than my previous half-assed import attempts. There is a lot of out of date data in CanVec, especially in the buildings layer - e.g. old industrial buildings that were demolished ten years ago and replaced with new buildings.

Cheerio John Nope, the whole idea is that small tiny (NTS tile or smaller) .osm files are being made available so then local area mappers can copy in the data manually. (And using aerial imagery toporama other sources as backgrounds. which help improve the map) And Yes, after you open up the file in JOSM, you can easily download the OSM area of it if you dont see anything in that area, you can upload it all. This will be true for alot of the country. (where there is no existing data). However, alot of time effort was spent on place the OSM data in the database, and we want to ensure its quality. So there is no automation, the automation was in the creation of these combined small .osm files. In many cases, the canvec data is old (and we know this) so it wont make sence to copy in buildings (for example) if you live in the area, you can check and see that this is true. Unlike the TIGER method in the US (where it was all dropped in remotely) the canvec .osm files will remain on the NRCan servers until a local area mapper wants to copy in the data in. Making changes after the fact are much harder. I (personally) plan on doing alot of manual copying in, but only for those tiles which are close to the 'Trans Canada Trail' and paved proposed bike dirt hiking routes. So for areas outside of this, local are mappers (with much more knowledge of the area) will be able to enhance the map with this canvec data local knowledge. Cheers, Sam P.S. there are a lot of mappers all over the country who wont know what is going on, perhaps we should make a FAQ wiki page explaining the process better?

[Talk-ca] franch / english names
Hi Daniel, Ok here's one. For the named features in Quebec, is french used as the primary language? I think there is a separate dataset in some cases for the Franch language version. I know that for the National Protected areas file, Yan Morin used the different rules.txt to get french 1st. This only effects a few features, mainly road names place names.

[Talk-ca] Gas Pipeline with 'type'
Hi, Just found another one, Im just fixing yup the wiki chart, and see that 118001* Way PipelineNatural gas, aboveground man_made=pipeline; type=gas Where it should be pipeline:type=gas http://wiki.openstreetmap.org/wiki/CanVec:_Energy_%28EN%29 http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dpipeline The wiki does indicate that 'type=*' should be used, however, it's standard practice to not use 'type', but instead use pipefline:type=* What is currently used? I didn't find it in the samples. And perhaps going with the standard tag of note=gas pipeline could be used instead?

[Talk-ca] Geobase vs. Yahoo...
I was looking around winnipeg's downtown (http://www.openstreetmap.org/?lat=49.89162lon=-97.14226zoom=16layers=B000FTF) and noticed that the street grids don't align all too well to what is in Geobase. It looks like the original outline of the street grid was done as a tracing from Yahoo. Looking at the yahoo imagery I've noticed it is quite difficult to see where some of the roads actually are since the perspective of the imagery is such that the roads are covered. As a result I'm noticing some areas where buildings are overlapping the road, or where the roads aren't straight despite me knowing they're straight. So I'm curious if I should consider the GeoBase data more correct and attempt to clean up accordingly? There's not a lot of good GPS trace data in the area so perhaps I just need to drive out myself to get some readings.

Re: [Talk-ca] Gas Pipeline with 'type'
note=* isn't a standard tag! It's based to avoid using that, as the key used for a wide range of things and for writing human-readable comments.

My friend is very comfortable traveling around the property. I'm not so comfortable with his offer to take me around the property (he has an employee ID, I don't). The airspace overhead is not restricted (at least not any more than non-company property nearby), so the road grid information could be obtained from a small airplane flying overhead.

Obtaining the street names from overhead would be a problem. The issue in my mind is the collection of GPS tracks (on the ground), would/could the employer object? Sure, they could do anything they like. The key to minimizing problems is to respect the company's ownership/right to use the land. I'd recommend asking for permission in writing (and get a response in writing). And get a vistor's pass for yourself (there could liability issues if you don't). Further could this sort of data collection cause any grief to Open Street Map? If you have their permission to be on the property, no problem with the data collection. Since you are creating the data, there's no data ownership problem. But I'm not a lawyer, so don't take the above as a professional legal opinion...
