Re: [OSM-talk] Random thoughts (Ed Loach)
That's a nice little discovery you made there. And in fact I've missed credit card notices and things like that due to updated email addresses or over-zealous SPAM filters. Perhaps given the amount of work that would be and also the fact that we don't want to SPAM people that simply don't want to be involved anymore the list of unresponded contributors could be sorted by number of edits. That way the people who are personally investigated would be a maximum return on investment of time and if many of the larger ones are successfully contacted then perhaps the still missing contributors will be those who weren't very active and didn't do much editing. Wouldn't want to delete half a country if someone merely changed their email and were too busy with life to stay active in the community. I'm glad I've joined the lists and know what's going on or 90% of Guyana would be deleted if I didn't approve the license change. Otherwise that would be a huge loss and I'm sure most people just don't care about the license arguments and just want their work to not go to waste. I would be pretty upset if years of work were deleted because I didn't get the emails. -Don. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] Time of changesets
I was looking at a changeset someone did on the main OSM site and was trying to figure out exactly when it was done. What I see is for example: Closed at:Tue, 17 May 2011 14:16:44 + So I figured maybe I didn't set my time zone prefs and it's my fault, so I went into my user settings and couldn't find anything like that. Would be nice if I could set my local timezone somewhere and see changesets and node info in local times. Am I missing it somewhere or does that need to be added? -Don. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] talk Digest, Vol 77, Issue 60
Well that's how *I* map out in the third world. :-) (user donaciano) Unsurfaced roads are very common and still considered streets, roads, etc... even the largest highway in the country is unsurfaced for many miles. In fact I've never even tagged a surface out here since it's normal for streets to be blocked by a huge sand pile while someone is building a house and you just have to back up and go around the other way sometimes. Or part of a road is washed away and you simply can't pass til someone fixes it. You'd be an idiot to try and follow computerized directions here and expect it to be perfect. Now where's my elephant?? :-) -Don.

Re: [OSM-talk] New user mistakenly nuking things
I wonder how frequently something like this happens in some unmonitored area in the US. I'm pretty sure it happens all over the place all the time. I'm one of very few people actively mapping Guyana and just last week this new user stuck a town in the ocean. So I politely messaged him and asked if he was sure it belonged there and he was pretty positive it was correct. So I sent him a permalink of it floating out there in the sea... whooops. Yeah that was an accident. There was also a kind of random 2m track connected to a town he made and some other little odds and ends. Enthusiasm is good though. I've often wished casual visitors could put things on the map anonymously and that they'd go into a big moderated bucket to await approval or rather end up in a openstreetbugs kind of layer instead. Or rather new registered users could have training wheels of some sort for their first few edits. Perhaps a set of Potlatch tutorials that would have them add the yellow brick road to the land of Oz, then the Emerald city... a few shops, barbers, tailors, a field of poppies, apple orchard with paths, highways, etc... Then you get to touch the real world. ;-) Or just skip the whole thing if you like to keep the wiki-purists happy. I think wiki believers should watch Ratatouille... yes ANYONE can edit, but not ANYONE can be a great cook. Or something like that. :-) -Don. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] splitting up planet file
Paul Houle said--- That said, my new strategy for dealing with large dump files is to cut the file into segments (like 'split') and recompress the fragments. If your processing chain allows it, this can be a powerful way to get a concurrency speedup. If more dump files were published in this format, we could get the benefits of parallel compression without the cost. This reminds me of an excellent solution to a similar problemhttp://users.softlab.ece.ntua.gr/~ttsiod/buildWikipediaOffline.htmlthat may be applicable to dealing efficiently with the planet.osm file. It comes from dealing with a similarly sized wikipedia english language bzip file. Basically you split it into chunks as you've already done but in addition you build an index that tells you which are the first complete entries of each chunk. Then what you've got is O(1) searching of a huge binary file. Piping the output of bzcat to osmarender means you're seeking through the entire file every time. For Wikipedia at least the entries are self-contained and in alphabetical order so this works. It's a great idea and allows a really fast offline wikipedia reader using all open source tools. Conceivably someone could adapt that for more quickly working with the planet.osm file. Now there's probably several huge reasons the concept wouldn't work with the planet.osm file, I don't know a thing about it's internal organization so I can't say... But perhaps there's some amount of data locality that can be exploited to make this work. If there's at least one type of information that we can use to seek through the file and find perhaps a country or a boundary of some sort, then it could be possible. Your post reminded me of the wikipedia dump solution so I thought I'd mention it. Regards, -DC ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] So how *do* you get GPS waypoints into OSM?
I'd just add that depending on your GPS the waypoints may not be in the GPX files. For example with Garmin GPS devices the Waypoints are stored in the internal memory and must be extracted using GPSBabel or similar. The GPX files copied off when in USB Disk mode will only be tracks. So if you're not seeing the waypoints it may be that you haven't gotten them off the device yet. In that case, I hope you haven't already deleted them from the device. :-o -Don. P.S. This is good info for the newbies list as well. *Hi all, Can anyone suggest any workflow, tools, whatever to get the waypoints that I have captured on my GPS (tourist attractions, hotels etc) into OSM? I understand the GPX upload interface doesn't support them. Just looking for some way to get an object in the right spot so I can edit it in Potlatch. One rule: no JOSM. I have a preference for online tools if possible. Thanks,* ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] How do I go about doing this?
There's a few tag adjustments I'd like to try and make in some different tools. I don't think this is really a newbie question so I'm asking here. For example there's a tag I've been using that encodes information useful in navigation but isn't being used in any renderers. (I'm not mentioning the tag right now because I want to know the process involved not debate my tag) At what point is a tag more or less recognized? Since wiki tag proposals seem to be ignored or unadopted, in what way can I ensure I'm using the correct tag? What is the process for getting a tag accepted into mapnik? What is the process for getting a tag supported in mkgmap? Thanks, -Don. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] New: A blackwhite base layer
Yeah that Glittermap is great stuff I gotta thank you for freeing my mind of the constraints of stuffy boring mapping. Now I'm thinking of cartoon style maps with text effect scripts run on Country/City/Town names... Old fashioned piratey maps with dragons in the water... Flippin' SpongeBob maps!! This is really a great way to add more fun to the maps and get more people excited about it especially graphic artist types who want to have a wide range of work in their portfolios. It would also be great for advertisements and theme park type guides. There's of course the isometric map, the 8-bit map styles, etc... Has anyone already made a wacky OSM styles page?

[OSM-talk] OSM into OOo document
I've been working on getting points mapped and shown on an image in an openoffice document. I'm asking with the list to see if I can get some ideas or if this is already done somewhere, perhaps I can avoid reinventing the wheel. Basically I'm using the method described herehttp://www.oooforum.org/forum/viewtopic.phtml?t=14979postdays=0postorder=ascstart=0to load an image from a URL into a document as a bitmap. What I'd like to do is use GPS coordinates from a database and show a few on each page mapped as a group. It's just an address list that shows all points on the map. A few ideas I have... 1) Look around for sample code to determine the tiles and zoomlevels that would holds the bounds I'd need to show all points in my set. I'd still have to figure out how to draw another image on top putting the points on the right spot as well as how to make sure the images line up if I need several tiles. 2) Find some sort of online API or website that will let me give it a set of points by encoding them into a URL and then download an image. I tried playing around with GPSvisualizer since waypoints can be put into the URL but the result is a full webpage with layers and javascript, not a simple image. I tried the JPEG export options but that doesn't allow an OSM background for whatever reason. 3) Find some sample javascript that does exactly what I need and get that to run in Openoffice as a macro since javascript is supported. So it seems my best options are #2 and #3. Maybe someone already knows where there's already a service or code to do close to what I need. Any other suggestions are appreciated as well.

Re: [OSM-talk] OSM into OOo document
Thanks, that's exactly what I was looking for. Only one thing left... since I can't seem to get the static map services to do it. I'm sure this is a fairly standard comp-sci type algorithm and solved years and years ago. It probably has a nice name for it and sample code. What's the algorithm to determine a comfortable bounding box for an arbitrary set of points? Basically defining a bounds that holds all the points then expanding it a certain percentage or so, accounting for the GPS coordinate system. Unless I missed a really obvious way to do it with the static map services. -Don.

This site lets you do some of these things: http://ojw.dev.openstreetmap.org/StaticMap/ , it's not perfect but it works for me. Any website based on C. Dauth's javascript classes also let you add markers visually or encoded in the URL, http://osm.cdauth.eu/map/ is an example. But then you need to make screenshots.

[OSM-talk] Rendering country outlines
Hello all. I asked this on the newbies list and it didn't get any replies so now I try on the big-kids list. ;-) I'm trying to figure out how I can render country outlines preferably exported to SVG where I can individually color them, and add charts and figures. I've found some posts talking about shapefiles and XAPI but they're fairly old and didn't have much detail to them, perhaps things are different now with 0.6 api and gradual changes in how the renders are done. I think it would be a nice practical use of OSM if there were a tool or easily reproducable way of getting various states, providences or countries rendered, millions of students need those shapes and probably just rip off whatever image they find googling. Thanks for any help. I'm comfortable with installing command-line utilities and have access to Windows, Linux and OS X. -DC ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
