Hi all, a quick update. I got together with the 2 other top mappers for this NTS tile area; 092b06, (a .5x.25 degree area (i think off-hand) and went over the canvec import data &process with everyone. We brainstormed ideas, and here's the results.
1 - for all of Canada, every tile that has osm data, extra care is needed. (priority is always given to the OSM data) and only the original mapper who traced or hand drew features can decide on if the feature should be replaced. 2 - All those mappers need to be contacted, and invited to a mapping party. The aim is that all local mappers get invited so that we can be looking at the data at the same time & deciding who does what, and exactly how it gets imported. 3 with the CanVec data, we examine the 'accuracy tag and the date of acquisition. We compare it against the osm trace & yahoo imagery & gps tracks & local knowledge. (this cant be automated, as each feature/trace varies.) 4 the script used to make the canvec.osm files is still in BETA, as we want to make sure that all default tags are right. -we dont want to find out later that i entered the FID tag or another tag wrong, or a big spelling error. 1 mistakes is magnified 30,000 timer over. 5 i'll make a zip file for each tile that will contain 1 file which is all the features combined to 1 area, and have each feature file also available. I'll include a local osm area file, with the latest data, so it will be easy to get an update of your area. 6 what we can do is right down on a wiki chart who the mapper are for each area (the main contact person) 7 sample area update (Ucluelet, BC) the aim for the next week is to get a majority of the features loaded and rendered. So more people can comment. Also to make tiles available to everyone, i should have the major cities tiles available soon. (im just a little hesitent, incase errors are found) 9 oh ya, the west coast trail will be loaded soon, so if anyone wants to beet me at making a tourist map for the trail & wiki travel article, the race is on! 10 - and finally, im updating the Ucluelet area, and experimenting to see about file size to see what i can get away with without bogging down the OSM servers, (while at the same time, examining the area to check data quality). So then for the later .osm files that need to be loaded, i can merge it ito 1 layer, and do that bulk upload thing, heres one of the change sets http://www.openstreetmap.org/browse/changeset/1364745 (check the history of the area to see the rest) ... 11 - it seems that anything under 1 meg of data is ok to upload using JOSM. (less than 50,000 things) Thats all for now, Cheers, Sam Vekemans Across Canada Trails
