Just an idea: what about having a separate tag for the "driveability" of the surface. Even when the surface material is basically the same, the driving experience with a bicycle my vary relatively much. The driveability tag could be used when driving experience is different from what one might expect based on the track type or the surface material of the track. For example, grades like -1, -2, or +1 and +2 could be used when the driving experience is worse or better than expected. This is indeed just an idea - I'm not making a more detailed suggestion, because I have very little experience with tagging (or anything else regarding OpenStreetMap :-) Cheers, Ari Torhamo ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

There's an important difference between this and "Potlatch using the main API". There are, I believe, some things that Potlatch can do that no other client can do, because the API to do it is not available. Specifically: * whichways_deleted gets deleted ways in a bbox, which the main API doesn't provide * getway_old has a "last deleted version", which seems different More problematic than the specific methods which do or don't exist, however, is the fact that the Potlatch way of interacting with them is *entirely* different -- so when a bug is fixed in the main API, the fix has to be duplicted in the Potlatch/amf_controller. This affects development of the server side APIs. You, at one point, put forward a significant amount of effort in improving the Rails code in amf_controller: that work benefited only Potlatch. If Potlatch was using the same backend rails calls (rather than just objects/models), then that development time could have benefited other clients as well. Potlatch has a very different way of interacting with the API. This way of interacting with the API has some benefits, and could allow for other clients similar to Potlatch to be developed without being tied explicitly to amf_controller, which is (at least at the moment) essentially Potlatch specific. (Things like 'masterscale' and 'potlatch_lon' seem to be indicate this anyway: maybe I'm wrong here.) I don't know amf: I see from the code that it's Actionscript Message Format. If there is a desire for supporting Actionscript Message Format for API actions, I don't see a problem with that at all: In fact, other encodings of OSM data delivered via the API seem a natural progression to me. (I'm biased here, having done this with TileCache, FeatureServer, WPServer, etc.) But I don't see that that means that Potlatch should have access to API methods which simply don't exist to any not potlatch-clients (or that clients would have to speak the same language as Potlatch to use them). > We have in fact started moving towards that goal with some work > that Steve did on some of the AMF calls. This is a different goal, that of replacing SQL with rails objects. A valuable goal, but not the same as abstracting the data selection calls to a single set of code, and then using that code to serve both the main API and amf_controller. > The problem is that it turned out that, even after I had optimised > the code, it is significantly slower to go through the rails object > model that to make direct SQL queries. This is interesting, but (imho) less relevant: The value of the above is actually doubled by this statement, since if Potlatch and the API were using the same function, one could optimize this, and since the code is used by *all* clients (not just one) you would see any problems with SQL calls more generally, and perhaps find it easier to debug them. (I think this is compounded by the fact that AMF is a format which is hard to replicate outside of a flash client, which makes server side developers less likely to have the technical chops to debug them.) A common library for API functionality between amf_controller and the various api_controller methods would help resolve this to some extent. > I think even Richard wouldn't mind too much making the AMF API use > the rails object model if it wasn't for the performance issues. Using the Rails Object Model is solving an *internal* API issue, but there still continue to exist two external APIs that use different backend data manipulation to achieve their goals. This seperation is what I see as more problematic -- and I think that's what Tom was addressing as well, though I could be wrong.

Well actually I don't mind the existence of the AMF API as such so long as it is just concerned with decoding the RPC calls and encoding the results, and it uses the rails object model to do all the work so that important code is shared with the XML API. We have in fact started moving towards that goal with some work that Steve did on some of the AMF calls. The problem is that it turned out that, even after I had optimised the code, it is significantly slower to go through the rails object model that to make direct SQL queries. Of course that probably affects the main API as well, it's just that it doesn't appear as a regression in that case in the way that it does with the AMF API. I think even Richard wouldn't mind too much making the AMF API use the rails object model if it wasn't for the performance issues.

API aside, the main reason to move to AS3 would be speed, the availability of more libraries and better development tools, and the larger developer community that Couldmade cites. Certainly though, the lack of a solid open source platform to run AS3 code on is an issue for a project like OSM. Not so much for a business like Cloudmade though, I expect.

Re: [OSM-talk] [OSM-dev] The future of Potlatch
Hi, > [warning - long ponderous e-mail follows!] I don't really see much of a problem with mutliple Flash editors being available. If they get something done that's better than Potlatch, why then it's good for all is it not? In general I have a problem with the built-in "uniqueness" of Potlatch or anything that might replace it; Potlatch is "the" OSM editor, the one that comes up if you click "edit" on the main OSM page. Until now Potlatch has enjoyed this privilege because there was no other suitable editor. If there are many competing editors - which one will get the "pole position" on osm.org? The editor and the features it supports will always very strongly influence what people map and how they do it. With JOSM, the concept is reasonably open; anyone can compile and run their own JOSM and make it available to third parties (as anyone using JOSM will not have difficulties running a program obtained from somewhere else), and plugins can be written and distributed. So even if JOSM were the only editor around, its grip on what people map and how they do it would not be very strong, since anybody with, say, an interest in turn restriction relations could provide a plugin that would make them editable nicely. Correct me if I'm wrong but Potlatch is, and any AS3 replacemend would be, a much more controlled environment, where the user has much less say in what editor and what features they want - you cannot simply run your own version of the editor against the live API, nor can you have local plugins or so. So that's the one doubt I would have - it must not come to CloudMade dictating what's behind the "Edit" tab on openstreetmap.org. But that could easily be alleviated by creating a set-up where *anybody* can operate an OSM editor on their site. In fact I would prefer that even now; give the user a choice whether his "edit" tab leads to Potlatch on RichardF's host or to the AS3 flash editor at cloudmade.com or the 100% javascript editor from crschmidt (or maybe even the JOSM applet), and anybody who thinks their editor is even better may add it to the list. If this core issue is resolved - i.e. the osm.org web site does not specifically endorse one editor and fail to list others - then I'd really say competition is good for all of us. I could imagine that if anything suppresses creativity in the current setup, it is not the fact that you use AS1; it is the fact that anything anybody wants to do has to be run by you and/or the people with [EMAIL PROTECTED] and only if you say yes then it gets into "the" editor, whereas with a project that doesn't depend on integration with the osm.org site (like Merkaartor or JOSM), you can simply try out something and offer it to people for immediate live use, even if the maintainer has completely different plans and doesn't like the concept. (But then again, look at the one-digit number of developers even with JOSM and Merkaartor... so don't excpect a boost if you make Potlatch less monopolistic.) > Part of me thinks that the most important thing is that Potlatch is > still available and users are offered the choice.

As an OSM community member I would like you to continue with your work and someone else do an AS3 editor for CloudMade, and then I want them both available on osm.org so that I can choose the one I like best (or the one that runs with my hardware/OS best, ot whatever). If you stopped working on Potlatch altogether, or if you re-did Potlatch in AS3, then that would leave me (the user) with less choice. Diversity is good.

Re: [OSM-talk] The future of Potlatch
Richard This is an interesting dilemma. First you should be proud of the fact that Potlatch is such a well regarded part of OSM. In some strange way it is flattery that CloudMade want to do this. Everybody knows how hard you have worked on Potlatch, and it is a very emotional thing to have someone want to take your baby away. If there is room for two editors within the OSM project, then there's probably room for three. You might find that it gives you the opportunity to take Potlatch in a slightly different direction. Try to see it as a positive thing. More editors means more competition, which will surely result in more innovation and better tools for everyone. 80n On Thu, May 1, 2008 at 6:35 PM, Richard Fairhurst <[EMAIL PROTECTED]> wrote: > [warning - long ponderous e-mail follows!] > > Hi all, > > A fairly weighty issue concerning the future of Potlatch has arisen, > and I'm completely baffled as to what to do - so I thought I'd "ask the > community" for thoughts and advice. > > CloudMade (Steve and Nick's VC-funded company set up to commercialise > OSM data, www.cloudmade.com) wants to commission a new online Flash > editor for OSM.

[OSM-talk] The future of Potlatch
[warning - long ponderous e-mail follows!] Hi all, A fairly weighty issue concerning the future of Potlatch has arisen, and I'm completely baffled as to what to do - so I thought I'd "ask the community" for thoughts and advice. CloudMade (Steve and Nick's VC-funded company set up to commercialise OSM data, www.cloudmade.com) wants to commission a new online Flash editor for OSM. It would, I believe, probably be written by developers from Stamen Design (www.stamen.com): some of you will remember that Stamen's Tom Carden wrote OSM's early Java editing applet, and they've also written a slippy map in Flash called Modest Maps. As you can imagine, this has taken me aback a bit. As I understand it, their main issue is a technical one. Potlatch is written in ActionScript 1, which is the same language as JavaScript, but for Flash. The latest version is ActionScript 3, which is much more like Java for Flash. The end user doesn't notice a difference, but the programming style is very different. CloudMade believes this is holding back the development of OSM: that if the editor were written in the latest version of the language, more Flash designers would come to work on it, resulting in a better editor. Steve cites OSM's move from pure Ruby to Ruby on Rails as an example of how a contemporary language encourages more people to contribute. And they're also worried that if I were run over by a bus then no-one would be able to speak ActionScript 1 and maintain Potlatch. I'm not so sure. I think people are beginning to contribute code to Potlatch; that as essentially JavaScript it's approachable enough; and that the problems of attracting developers is symptomatic of core OSM in general (as per http://trac.openstreetmap.org/log/sites/rails_port). I hope that Potlatch, as something maintained by an active community participant _for_ the community, has demonstrated a pretty rapid rate of improvement anyway. It's meant to be small and compact, of course, not a a bells-and-whistles editor like JOSM: nonetheless, in the last few months, for example: it's become the only editor yet to offer revert/history, gained very good relations support, background layers, flexible GPX import, etc. And there's a lot of stuff on the way, mostly focusing on usability - from a generic 'undo' and pop-up help panel to a new, super-user-friendly tagging panel with draggable POI icons and things like that. It's got faults, everything has, but it's come a long way in the last year. For what it's worth I think it's the best thing I've ever coded. For most purposes AS3 probably is a better language - except for the fairly major proviso there's no open-source player even in development. Indeed, if I were starting all over again I'd probably do it in AS3, and in a couple of years I may well migrate Potlatch to AS3 (or 4, or whatever) anyway. But right now it's more important to spend time improving usability for mappers, given that - like most people here - I do have a full-time job which isn't OSM (which isn't computer-related at all, in fact) and consequently time is not unlimited. So I really don't know what to do. Part of me thinks that the most important thing is that Potlatch is still available and users are offered the choice. Part of me thinks, well, if there's going to be a new Flash editor, there's no point in me doing any development on Potlatch from today forward. Part of me wants to say "well, screw you" and walk away. And part of me wants to take CloudMade up on its OSM Grants scheme (http://blog.cloudmade.com/) and say, ok then, I'll announce a medium-term feature freeze, take a few weeks' holiday, learn AS3 and recode it for a large amount of $$$.

[OSM-talk] New Potlatch
0.8c is one of those "little things that mean a lot" updates: - When you add a point into a way where it crosses another way, Potlatch automatically makes an intersection. - Points and ways are now bigger at high zoom levels for those people without superhuman fine motor skills. (But you can turn this off using a new preference.) - Double-clicking to end a line doesn't restart the line if you've already clicked. - Click/drag detection is much improved. And in some related news, the Gnash (GNU Flash Player) devs - in particular Sandro 'strk' Santilli - are doing really well in improving Gnash to work with Potlatch. strk has even become an OSM mapper which can't be bad. :) It's going to be interesting to see how Adobe's removal of licensing restrictions on SWF, just announced, benefits Gnash.

[OSM-talk] clipboard on handlebars
When I got home some of my notes for my waypoints didn't make sense. I realized I was trying to take note only every third or forth waypoint and misremembering them. Sometimes the simple solution is the answer. I grapped some big clips from the office and a folder with a lever action clip. I bent back the cover, trimmed it down to a triangle shape, cut a notch for the speedometer cable etc. My data is much better. -- http://bowlad.com ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
[OSM-talk] [CARTO-SoC] BCS AWARDS deadline 30 May 2008 (fwd)
I think we should nominate OSM for the 'Ordnance Survey MasterMap Award for Better Mapping' . cheers martin -- Forwarded message -- Date: Thu, 1 May 2008 15:09:30 BST From: C Neal <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list CARTO-SOC <[EMAIL PROTECTED]> Subject: [CARTO-SoC] BCS AWARDS deadline 30 May 2008 BCS Awards deadline The BCS Awards will close to entries on May 30th 2008. The British Cartographic Society (BCS) recently revamped the Awards scheme to encourage entrants from all disciplines in cartography, and to showcase products created through traditional or new, even experimental, techniques. The BCS aims to help promote the best of cartographic products and highlight good cartographic design in the UK and abroad. As part of the changes, two awards were added to the programme to assist in covering all disciplines. Firstly, The Stanfords Award for printed mapping is designed to encourage any printed products to enter, from coffee table atlases to wallpaper or maps featured in leaflets and topical articles. The Avenza Award for electronic mapping was also added to allow digital products such as interactive and web maps to also compete. Entries can include power-point presentations, interactive CD-ROMS, or websites. These two awards join the established John C Bartholomew Award for Small Scale Mapping and the Ordnance Survey MasterMap Award for Better Mapping. Not only will the winners of these awards receive a crystal trophy and certificate, but they also go head-to-head with each other to receive the prestigious honour of being crowned the Best Mapping entry and presented with The BCS Award. (Closing date for all the above entries is 30th May 2008) We are delighted to announce the introduction of a new award for UK children, to run in alternate years to the ICA Barbara Petchenik Children's Map Competition. The UKHO Junior Mapmaker Award is designed to encourage map making in children aged 7 - 16. (Closing date is Saturday 19th July 2008) We also continue to support the NGS New Mapmaker Award in conjunction with The National Geographic Society (same closing date), and The Henry Johns Award for the best Cartographic Journal article sponsored by Lovell Johns. If you would like to enter any of these awards, entry forms are available on the BCS website. See the Awards section on http://www.cartography.org.uk Information about the winners from 2007 is also available on the website -- Clare Neal BCS Webmaster http://www.cartography.org.uk -- Distributed by CARTO-SoC, the Society of Cartographers Mailing List.

Re: [OSM-talk] Bulk Data Import how-to and tips
Hi, Patrick Maybe there is a better way, but this is what I would do: - get a shapefile of Luxembourg (or a simple polygon shapefile that contains all of Luxembourg). Let's call it lux.shp. - download the roads for Luxembourg currently in OSM from http://download.geofabrik.de/osm/europe/ Now you will need a GIS application: - select the roads tagged as motorway, motorway_link, trunk, trunk_link, primary or primary_link from that shapefile and export them to another shapefile. - perform a buffer of that shapefile (for example, use 100 meters for the radius) - perform a difference operation: lux.shp minus the buffer you have just created - finally, clip the official shapefile of the Luxembourg roads with the result of that substraction and export the resulting shapefile to the OSM format with that python script. And then, you will have to carefully connect those ways with the current ways in OSM, and revise the tags, of course.

It was because of the difficulty of defining unpaved surfaces that this thread branched off.

This way the client (printing/routing-app, etc) can decide which sort of surface to use. For example I have no problem using fine/medium gravel tracks with my "normal" bike at all, while others on this list would tag such ways as "bicycle_suitable=mtb"... And what about incline? is it part of the "bicycle_suitable" tag or not? I think its better to invest the time in better surface tagging than, rather than subjectively tagging things that are only of use for one specific group of users. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

[OSM-talk] Searching and alt_name
I'd like to encourage you, when editing the map, to think about how people might search for the features you are adding to the map and try to accommodate them, to try to be helpful to future consumers of the map data. Using alt_name is one way to do this. The namefinder already deals automatically with some mechanical variations(*). But there's often variations in what something is known as which can't (easily) be accommodated automatically. For example, I was reading Richard's blog from a few weeks ago about Heathrow Terminal 5, where he says that we correctly yield the result in a search. Yes we do, but what if someone had asked for "Heathrow Airport Terminal 5". Yesterday, that wouldn't have got a hit; today it does because I added an alt_name tag to it to accommodate this variation. Namefinder recognises alt_name. Of course you could put variations in the name tag (maybe separated by semicolons, or in square brackets, or some such), but then it will all render, possibly rather verbosely. You might want just "Terminal 5" to show up on the map rendering, given that "Heathrow Airport" would be rendered separately in the middle of the ring of terminals and so be obvious, but searches for "Heathrow Terminal 5" still be successful. Another example: the search test for tourist attractions has "British Airways London Eye" and "V&A" as test searches. There's arguably no need for the rendering to say other than "London Eye" (or "The London Eye"?) but a search would ideally respond to its full title. Similarly, the map is rightly labelled "Victoria and Albert Museum", but searches should respond to V&A. Incidentally, variations aren't needed for just for the presence or absence of the word "the" (or le, la, el, il, die, das, der), which is automatically dealt with. Another example might be function vs name. The name of an office block in Cambridge is "Eastbrook", but if someone searches for "Inland Revenue, Cambridge" it might be nice to be able to offer "Eastbrook" as the answer. (That works, but "HMRC, Cambridge" or "Tax office, Cambridge" don't and arguably should. Conversely "Chailey House, Bedford" doesn't work - today - but "Inland Revenue, Bedford" does). It's usually POIs affected, and it is usually just variations in names rather than completely different names (when you would probably want them rendered anyway). Occasionally though street names also have this problem. Consider one I came across recently: signs say "Long Horse Croft". You can imagine someone might search for "Longhorse Croft" (especially as that's how the district council list it on their refuse collection days list). I guess in principle, I could automate this at some point, but it is hard, especially the other way round (signs say "Longhorse Croft", searcher asks for "Long Horse Croft"), so a variation would be helpful here, though purists will say "don't code for the inadequacies of the tools". David (*) in things like case, abbreviations (Rd vs Road), accented characters and diacriticals (München vs Munchen or Muenchen), ligatures, possessives (St John's vs St John or St Johns) and some Germanic concatentations (Potsdammerplatz vs Potsdammer Platz). We are also used to dealing with alternative languages with the name: tags, so 'Londres' will find 'London'. Also, the item description is included, so you don't necessarily need to say "school" in the name - "King Edward School" will match name=King Edward, amenity=school (though not at present Konig Albert Schule" unless schule is recorded as part of the name). ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

Perhaps this is the better way to think about it. I generally don't like subjective tagging, but in this instance giving an opinion about how usable a section of way is might be better.

Thus far, I was using "unpaved" exclusively. I too have been using "unpaved" to date and will continue to do so, however I accept that in some instances I also want to state what the surface is made up of and haven't really got to grips with that for unpaved surfaces. Paved surfaces are easy enough (including those covered with chippings). These type of scenarios crop up: Farm tracks in Norfolk where dry sand fills the ruts making cycling near on impossible. Farm tracks in Cumbria where natural boulders and cobbles protrude regularly through the surface. Tracks that have had potholes filled in with railway ballast. These are just a few scenarios, none of which I find an easy way to tag, thus to date I have ignored doing so.

If the >latter, which knobs have you chosen? My idea is to try and shield the user from the XML file altogether. Rather than get a user to open an XML file, I'd like users to be able to simply open an OSM file, download data from the API, or retrieve data from a PostGIS database, and then use the UI to define styles for OSM key/value combinations. Ideally also I'd like users to be able to select high level types (which map to certain key/value combinations) as Potlatch already does. I'd also like an "OSM browser" mode, where a user can pan the map and new data gets downloaded from the API, and then cached locally. I'd also like the users to be able to define, and order, layers for their map. Nick ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

Alternatively you can hide the section completely by rendering the shed over the top of the railway by appropriate use of the layer tag. they are the only options I know of right now and cant really think of a good alternative anyway.
