Dear Canadian OpenStreetMap contributors, The upcoming move to the Open Database License means that a small number of users have chosen for their contributions not to continue within OSM. Since we want OSM to remain the best map in the world, we can remap the affected areas now, so that little difference is noticeable on changeover day. The License Working Group would now like to formally urge Canadian mappers to look at your local mapping areas, contact anyone who still might agree and then remap. This is a pilot project to engage global mappers on a country-by-country basis.
Critical mass for the change-over has certainly been achieved. On a global basis, over 96.8% of nodes and 96.3% of highways [1] are by folks who have accepted the new terms. However, we still have globally 36 million nodes that may not survive the license change and 4.2 million problematic ways where some or all value will be lost [2]. This is still a large number, particularly if they are in your local mapping area, and we would like to reduce it. In Canada, the situation is slightly better than the global average, with 98.3% of nodes and 96.7% of highways coming from folks who have accepted the new terms. http://wiki.openstreetmap.org/wiki/Remapping is a specific up-to-date resource on remapping and http://wiki.openstreetmap.org/wiki/Help_preparing_for_the_license_change give broader background information. Frederik Ramm's excellent License Change View on OSM Inspector [4] helps pin point problematic areas and users who have not yet agreed to the license upgrade and new contributor terms. There are license-status tools for both JOSM and Potlatch2, to aid you in mapping. I have found the following approach helpful in cleaning Cambridge and starting to clean Toronto. Contact mappers with problematic edits in my area and ask them to consider agreeing to CT/ODbL. Remap the objects effected by accounts that do not then agree. I'm not contacting every mapper with problematic edits. A very small number of OSM accounts have already declined CT/ODbL for their own reasons. Many more contributors have not replied either because they have lost interest or contact with the OSM community. Of those, I've found that many have responded positively by agreeing with CT/ODbL. Some have even started mapping again after a long hiatus. I see no pattern in who agrees; some are accounts with only a few edits and others with many edits over months or years. I've also been remapping objects effected by declined or non-responsive accounts. Often, this remapping can be done to high quality from a combination of aerial imagery and canvec data. I've gone out to resurvey some areas as well. I've been able to clean Cambridge of non-compatible edits in the course of just a few editing sessions with only small changes in my mapping techniques. 1) I look at the license status of the area in the course of my normal mapping. While mapping, I make sure to clean problematic objects rather than just editing them. Every mapper should be aware of the license status of objects while mapping. If you ignore this, you might be making improvements that will be discarded in the license change. 2) By contacting a few non-responsive mappers, many objects have "cleaned themselves" when those mappers agree. This is a really good thing, especially when they become active mappers again! 3) Sometimes, I take a few extra minutes to clean some other surrounding objects. 4) Sometimes, I plan and resurvey an area to clean it. Please join me and many of the other mappers who are taking an interest in making the license upgrade as smooth as possible. As with any mapping, looking at the map from a new perspective is interesting and fun. And every improvement that we make now, before the cutover date will be made with the care and attention that local mappers bring to every edit. Below, I have included links to several Canadian cities in OSMI. Sorry that the links are so long. :-) Best regards.
