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 There is a lot of out of date data in CanVec, especially in the buildings layer - e.g. old industrial buildings that were demolished ten years ago and replaced with new buildings.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? (i could, but im afraid that others wont understand it :-) Looks good, much better than my previous half-assed import attempts.

[Talk-ca] OSM CanVec.
I think I may have missed the goal here? Are we evaluating the OSM files and trying to make the source better or just requesting OSM files and putting them in? I'm ready to go if we're just putting them in. ;-) ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
Re: [Talk-ca] OSM CanVec.
Hi Mike, You did not miss anything, you are giving comments on a sample - as expected! - About missing names, Canvec features are not named. However you can find some toponyms. - About missing tags on multipolygon. The tags have been placed at relation level, not on inner or outer ways. - About duplicate ways for water bodies. You have found a problem with the Canvec product - support team has been advised. - About out of date data - residential area, sports track, buildings. Here is what I answered to Richard yesterday concerning building, it applies to your findings ... It reflects the fact that there is no more complete map update program at federal level. The updated content is provided through the GeoBase initiative. As buildings are not a GeoBase layer, they have not been updated for a while. That is where Osm mapper could eventually make a difference. Cheers, Daniel -Original Message- From: talk-ca-boun...@openstreetmap.org [mailto:talk-ca-boun...@openstreetmap.org] On Behalf Of G.
