[Talk-ca] Coastline missing in Lake Superior - in case anyone notices...
I'm currently working on importing CanVec data around Lake Superior... the coast line was really getting in the way, so I'm deleting it. I'm actually joining them to the CanVec water corners... but it's probably creating a coastal hole, not really sure if the join is actually working. My plan is to finish loading all the coastal areas with the canvec data. Then joining the big body of water with a single relation, on the Canadian side. That will become the new coastal waters object, when finished. On the USA side I'll just join the existing coastal waters object across the USA/Canada boarder. I should have the entire lake finished by the end of the week... I hope. I just wanted to post this in case it sent up red flags somewhere. ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca

I thought of that, but I'm dealing with over a million coastline objects.

Re: [Talk-ca] Coastline missing in Lake Superior - in case anyone notices...
thanks, i'll try that. just add in the natural=coastline to the waterbody and reverse the ways so then its correct. ... but also adding in the coastal line along the areas that have a smaller natural=water polygon. so it's still a slow steady process, no matter how it's mixed :) ... as long as the end result is the same, it's all good. cheers, sam On 8/10/10, G.

I'm perfectly fine killing the coastal tag from the Canadian side on all fresh water lakes... makes more sense to me.

As Quick Draw McGraw would say, Whoa! Hold on there Pardners! Please don't just delete and replace a large international body of water without TONS of discussion with the affected community first. There is a very high likelihood that editing an object this large will break in the middle due to a timeout. That will make fixing it ever harder. And it will all take time which is almost certain to cause a ruckus, if the affected community is not involved before the problem occurs. This in not a race.

Re: [Talk-ca] new brunswick mappers
cool, do you plan on submitting your road network updates to nrcan? the current nrcan road network is probably old, so it would be great to submit the data upstream as the process for gettin it to osm, will be a 6 month lag time. this way, as your creating your new version of separate data, we already have a source for the data. my interpretation of osm-law is different. but if you can act on behalf of the new brunswick dataset and give direct permission to use the data directly in osm, it can potentially get into openstreetmap faster than via. geobase via. canvec. In the mean time, there are other mappers in the region who are doing a great job. but yup, i'll help too. im currently mapping in a connected line of tiles directly across the contr fortunatly, in the big cities, it will be already done before i get to it. i do have a timeline (before 2012) to get it done, so i'll do my best to get at least the basemap for the provincial trail network complete. sam On 8/10/10, Connors, Bernie (SNB) bernie.conn...@snb.ca wrote: Sam, I am in the Fredericton area.

Re: [Talk-ca] new brunswick mappers
Hi Bernie, I must apologies, I responded to the message on my mobile too quick without reading the message in its entirety. On Behalf of the OSM Canada community, i'd like to thank you for providing this data to the OSM community. From what i can see, with this data announcement, shows how the Province of New Brunswick, is in line with todays fast-changing advancements of technology. (Sometimes so fast that it remains difficult for even the industry to keep up with this globally changing GeoSpatial environment.) (copied from the website) http://www.snb.ca/e/1000/1000-3/e/1000-3_001_e.asp Background Since late 2006, the Government of New Brunswick has been working toward implementing its renewed vision for geomatics in New Brunswick. The culmination of this effort is a collaboratively built and maintained Spatial Data Infrastructure (SDI) for New Brunswick, now referred to as GeoNB. Simply put, an SDI is a shared data environment that improves access to geographic information; however, the GeoNB initiative involves much more than simply sharing data. It also involves sharing tools, technology and services (or applications) built as part of, or linked into, the core infrastructure, along with guiding principles, policies and data standards. As one of its main objectives, GeoNB will facilitate the sharing of geographic data and services among government departments, non-government organizations, industry, not-for-profit companies, academia, and the general public. GeoNB will even share the infrastructure it is built on by making services and applications available to users. GeoNB will evolve and grow as user needs change and various components (i.e. data sets, tools, services, partners, participants, etc.) are added over time. Although a great deal of work has already been done to lay the foundation and build a collaborative environment, the release of the GeoNB Map Viewer is, for many stakeholders, the first tangible deliverable of the overall GeoNB initiative.

If I invest too much time in OSM it could be perceived as counterproductive to our New Brunswick Road Network (NBRN) project. Hi Bernie! You might find it worthwhile to facilitate a regular meeting of OSM enthusiasts without the additional organizational requirements of a mapping party. I do this for meetups in Toronto and Kitchener-Waterloo and my commitment is essentially, pick a time and place followed by by there and have fun talking about OSM. The benefit to the OSM community is that only a few will take the time to organize such an event, but more than a few would be willing to attend if somebody else organized it. You are probably saying to yourself, Well, sure I would go if somebody else est it up. And that kind of proves my point! ;-) Our meetups vary from energetic discussions of OSM related details, to a few regulars catching up on gossip to meeting newcomers and watching them get more enthusiastic as they edit the map with an experienced OSMer to encourage them. Really. You should do this. We are providing a free online mapping tool called the GeoNB Map Viewer http://www.snb.ca/geonb/. Please feel free to use the maps here as a reference. The road data displayed in the GeoNB Map Viewer comes from several sources and is not one homogeneous dataset. *Most* of the data displayed in the GeoNB Map Viewer is governed by an unrestricted use data agreement: http://geonb.snb.ca/geonb/Agreement_en.pdf Well this is mixed news. Mostly nice. ;-) The map viewer has very pretty icons. I did not see any obvious indication of which data is covered by the above license. Since you say some is under another license I think it will be important to know the difference. The license above is pretty good from a municipal data license point of view. Some of it still concerns me. On one hand 3.1 allows licensee to relicense and sublicense - that's good. On the other hand 4.5 requires licensee to license others with the same terms. To my layman's eyes those seem contradictory. Also 4.4 requires indemnifying SNB. If SNB needs to rely on OSMs funds to protect NB in a legal battle, there is trouble afoot. ;-) Of course, OSM is also licensed under terms like as is and no warranty as well. SNBs requirement for attribution seems quite reasonable if SNB is the sole source of data for a map project. In OSM things work a little differently. We expect, over time, that any portion of the map will have had many contributors, even if a large area came originally from a single data donor. So in OSM we expect attribution to the project as a whole to satisfy all attribution requirements. Then further details can be had (for technically acute observers) by way of history files, and listings on the wiki. For example, the disclaimers and attributions of several data donors are shown here. http://wiki.openstreetmap.org/wiki/Attribution The form of this attribution may change over time as there is a practical limit to the size of a wiki page, but the attribution and disclaimers should continue to be available, even if in sub-pages. Do you think that SNB might agree to allow the inclusion of certain of their databases into OpenStreetMap under the current and future OSM licenses and Contributor Terms? That seems quite a lot to ask but it is also a way to expose the SNB data to a lot of potential users. This is rather more license-talk than I had hoped to have tonight. I would really like to see some OSM presentations at the upcoming Geomatics Atlantic Conference in Fredericton, Oct 28 and 29. The call for presentations has been extended: http://www.geomaticsatlantic.com/call-for-papers I had a look at that but have a pretty busy October lined up.
