You should use metric it's easier since metric distances were based on a rough approximation of the circumference of the earth ;) 1 degree of latitude and at the equator, 1 degree of longitude ~= 100km, so every decimal place from there is an order of magnitude less. 0.1 ~= 10km 0.01 ~= 1km 0.001 ~= 100m 0.0001 ~= 10m 0.1 ~= 1m 0.01 ~= 10cm 0.001 ~= 1cm An inch was standardised based on metric :) 1 inch = 2.54cm exactly ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

[OSM-talk] iPhone vs Android - OSM shootout
Hi, I'm looking for the best mobile phone for OpenStreetMap. Which mobile phone do you think is better for OpenStreetMap? Things for consideration are: - onboard GPS precision - applications for GPS logging - applications for POI collection - battery life when mapping (how long can you map) Please share any experience that you have with any or even better if you had experience with both of them. I only user iPhone for a short while, and haven't even seen Android for real but I ran Android emulator via SDK to get a feel for it. Here are some of my thoughts... Android positive points: - platform on the uptake, more apps coming every day - nice POI collection app [1] - runs multiple apps at once - quite open platform Android negative points: - less apps than iPhone, both for OSM and general - not so good as multimedia player (video and audio podcasts) - a bit bigger and heavier than iPhone iPhone positive points: - lots of apps, both for OSM and general [2] - CloudMade MapZen POI collector supports for iPhone [3] - multitouch interface - great multimedia player (video and audio podcasts) - nice deal for a 2 year T-Mobile contract iPhone negative points: - runs only one app at once :( - pretty closed platform :( - quite expensive, no carrier in Croatia offers it in contract deals :( [1] http://maps.bigtincan.com/btc-mapper.php [2] http://blog.cloudmade.com/2009/03/19/bring-cloudmade-maps-to-your- iphone-application/ [3] http://mapzen.cloudmade.com/mapzen-poi-collector -- pratite me na twitteru - www.twitter.com/valentt http://kernelreloaded.blog385.com/ linux, blog, anime, spirituality, windsurf, wireless registered as user #367004 with the Linux Counter, http://counter.li.org.

Then make a personal rule of always uploading your data to the server just as you would with Potlatch, then you never have to worry about local data and can just get it from the server.

I don't think this would be a good idea, they aren't GPS traces, it would also remove or make more difficult if things need to be attributed to know what to attribute to whom.

[OSM-talk] Potlatch 1.3
Hi all, I'm pleased to announce Potlatch 1.3 - a new version with one major improvement. Potlatch now lets you zoom in as far as zoom level 23. Previous versions only went up to z19, and even then with some loss of positional accuracy. This makes Potlatch much more suitable for tracing buildings, and other fine detail, from high quality aerial imagery like the NearMap imagery available in Australia. Don't forget that there's the option to 'Use thin lines at all scales' to make high-resolution work easier, too. A fair amount of the scaling code has been reworked to cope with this, so if you spot any mishaps on the way, reports at http://trac.openstreetmap.org/ are welcome as usual. This might be the last major revision of Potlatch 1.x - because work is now well underway on Potlatch 2, which is a complete rewrite with some whizzy new features. But more on that anon! cheers Richard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] Does Google use automated tracing from satellite imagery ?
I find the Yahoo satellite imagery useful for tracing in JOSM with wmsplugin, but when I just want to gaze at stunning sights of Earth's surface I go to Google, the quality of whose imagery never ceases to amaze me. I have noticed that in many places, in countries in which Google does not have significant commercial interest, even many villages have part of their street grid mapped. But looking a little closer, this is a partial mapping of a seemingly random subset of the grid, and none of those streets have names. Example in Takoradi, Ghana : http://j.mp/7Ay7wZ. This looks like what some grid recognition automaton would produce if configured to only trace the streets it detects with a certainty above a certain threshold. The result is imperfect, but it looks like a nice way to kickstart manual mapping of an area with the techniques we currently use. So is anyone aware of automated tracing techniques that Google might be using ? Is automated tracing from legally available imagery something that the Openstreetmap project should study ? Street grid detection and automated tracing would make a nice JOSM plugin wouldn't it ? Lakewalker does it for waterlines (http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Lakewalker) and coastline tracing of Landsat imagery using other tools has been experimented with (http://www.mail-archive.com/talk@openstreetmap.org/msg12661.html). Other people have been playing with Potrace and Autotrace (http://wikitravel.org/en/Wikitravel_talk:How_to_draw_a_map#Automated_tracing_potrace_vs._autotrace) But I have found no mention of street tracing automation yet. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] Fwd: Idea: shp2osm2gpx2donateBYseparate login
Hi everyone, What do you think of the idea to convert the shp files to OSM, then to GPX and upload it that way? This way, we (at a minimum) just have a gpx track of where the data that is available, geographically is. It doesnt mean that the features will end up being uploaded, it just provides a 'tracer'. This can be VERY handy for the leavely mapped areas, as well as not so heavely mapped areas. (since its a 'guide' 1 of many gpx tracks around) This way, i can create a separate login for this, and just upload these 'created' gpx tracks, and it will NOT interfer with ANY osm data. Would it be possable to allow me to upload these tracks?

Some of it list 'trails' as being 'on road with vehicles' so that would be a 'tertiary' or 'unclassified' instead, so im wondering if i could convert the file to gpx and upload that (under a different login) That way, it is all available, at the min. tracable. This can prove 'helpful' in any area, so that it can be 'traced' or used to correct (or re-align) tracks where people have already mapped. Thanks, Sam P.S. For each import source. I think that it's best if i create a new login for it? -- Twitter: @Acrosscanada Blog: http://Acrosscanadatrails.blogspot.com Facebook: http://www.facebook.com/sam.vekemans Skype: samvekemans OpenStreetMap IRC: http://irc.openstreetmap.org @Acrosscanadatrails -- Twitter: @Acrosscanada Blog: http://Acrosscanadatrails.blogspot.com Facebook: http://www.facebook.com/sam.vekemans Skype: samvekemans OpenStreetMap IRC: http://irc.openstreetmap.org @Acrosscanadatrails ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Mapping a favela (slum)
Congrats, Arlindo! Here in Kibera, we purchased recent satellite imagery, but you can only tell so much. And we use the Garmin eTrex Legend HCx. Kibera is very dense, and the tracks are often not that precise. But in combination, we can have good certainty of where the paths lie .. the GPS tracks give a rough guide, and interpretation of the imagery with local knowledge helps a lot. So my recommendation is the combination :) We're using Walking Papers too. We need to put some more work into WP .. Kibera POIs are so dense, some of the nodes aren't rendered, which can be confusing.

It has a funicular system to the top, and I've added a couple of POIs. However (and obviously), the GPS tracks were completely erratic due to the sub-meter wide footpaths. I've tried with my Nokia N95 GPS. It is very dense [4] there, you can check how erratic was the log [5]. But it is already something! :D Judging the satelite image, what do you think it would be better: purchasing sub-meter pixel satellite imagery, an expensive GPS unit or a combination of both? I believe that once the main footpaths/stairways are mapped, we can have mapping parties with Walking Papers. I'd love to have the kids helping by adding POIs, for instance. Perhaps talking with the local school...
