For example, when creating a blank POI, the user would need to doubleclick to create the point. Now what happens with trackpads (especially Macbook ones where you have to physically depress the trackpad for a click), is that there would be a slight movement introduced between the two clicks. Problem: Potlatch2 doesnt seem to recognise a double-click to create a POI if the mouseposition changes between clicks, instead going into line creation mode. This confuses especially novice users, who don't then know how to cancel this unwanted behaviour.

On Mon, Mar 5, 2012 at 10:58 PM, Michael Daines mich...@mdaines.com wrote: Hi everyone, I'm writing to seek opinions about a possible Google Summer of Code project. I did GSoC in 2010, and I'd like to apply again this year. My project in 2010 was a simplified, web-based map editor. Since the wiki page for project ideas mentions that proposals for the development of existing OSM infrastructure would be preferred, I was having a look at the API v0.7 page, and noticed some interest in a monitoring feature. My proposal is to build a monitoring service to augment the existing API, similar to the Twitter streaming API [1]. Users would request to receive map updates matching tags or which involve elements in some area, and updates would be sent either over a persistent connection (as Twitter does) or possibly by making requests to an endpoint specified by the user. My general idea for the architecture is basically to grab diffs and then send the relevant parts to clients depending on what they've asked to receive. Clients of such a monitoring service could do things like send daily email updates on map activity to users interested in a specific area or tag, invalidate tiles in custom-rendered maps, or assemble a subset of available OSM data for fast, up-to-date querying within that subset (a single city, for example) without worrying about making lots of requests to the OSM API. That third application would be useful for solving one of the problems I ran into with my 2010 project -- I was optimistically loading map data with bbox queries as the user panned the map, which was too slow on the production API to be practical (and probably isn't what that part of the API is really meant for). Another project idea might be to work directly on a service which would provide fast querying on tag or area subsets. However, the project as I've proposed it above seems to me to be sort of a generalization of that, and also seems like it would require less bandwidth and disk space. I wouldn't worry about monitoring area changes, as we have OWL[0] (supposedly being integrated with the Rails port), Changepipe[1], and possibly others that do this already.

Re: [OSM-dev] OSM StreetDensityMap
Cool. I've been wanting to give hadoop / map/reduce a try with OSM data but the wiki does not offer much. It would be nice if someone with some experience would create a wiki page. I'm sure it would be interesting for the community as well as GIScience folks to have a place to start. If I've some time I'll create a wiki page for osm on hadoop (and post it here). It gives also a sort-of osm activity map. Well, it does and it doesn't. You'd have to compare it to a reference road network density map to appreciate the activity of the OSM community in representing reality in OSM. That's right. I see a lot of potential for this beyond 'simple' visualisation. Systems like TagInfo and OWL could benefit, maybe? Does your framework lend itself for (near) real time processing of OSM data, or does it only work with snapshot data? MapReduce itself is a programming model. It allows you to process data by defining map- and reduce-functions (and is thus quite easy to learn). It's implemented as a distributed batch processing framework and allows you to process TBs of data on a cluster of up to hundreds of nodes. The real benefit of using such a system is that it scales linearly (well, you could say between O(n) and O(nlogn)) and single systems (like relational DBs) can't scale that high. Our cluster was around 10 nodes, and it took us about 3-4 hours to create the map and store it on HBase (although the cluster was not busy the whole time) [where the uncompressed planet-file is about 200GB]. That said, you can run small jobs on hadoop/mapreduce in a few minutes (= near realtime) and it would be be possible to * process the planet-file once and store the results in a DB * process the planet-file diffs (e.g. hourly) and update the DB TagInfo-like systems (aggregating big data and creating statistics) could definitely be built using hadoop/mapreduce. - npl ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

One of the larger criticisms of GSoC is that the projects are often abandoned after the summer. Therefore I'd suggest that if you're going to work on something, you work on adding a feature to an existing OSM project, rather than going off and creating a new project.

When you mention changes to large relations and widely dispersed objects, I was wondering if you had any specific use cases in mind? I'd also be interested in hearing what kind of expressions you might expect to be able to use. For example, I was thinking you could say something like give me updates for things with the tag highway=residential and is_in=Canada. It looks like Changepipe is similar to what I'm proposing, and OWL is sort of the opposite. My idea is that clients would tell the API they're interested in hearing about something (a tag, an id, some expression involving multiple tags, an area) and then updates would be sent to them as they happen, instead of polling for what's happened in the past. This scheme would reduce the number of incoming requests at the cost of the client being responsible for receiving the information and doing something with it. I believe this approach would reduce the complexity of processing new information since it would be known in advance what updates are required. Another approach would be that clients tell the API they're interested in getting information about something and can then request an RSS feed which has recent updates. But instead of requesting an RSS feed for an arbitrary watch expression, it's this sort of bin which stuff is thrown into as the map is updated. This seems easier to translate into something you can do manually with a web browser than what's described above. I'm curious to hear which of these approaches would be useful to people interested in this sort of thing. It seems like being able to ask for RSS feeds would be more immediately useful, but having data pushed to clients would allow for more flexible applications. -- Michael ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

[OSM-dev] Info request on: additional GIS layers
Hello Some governmental institutions are willing to use OSM software stack and share their information. For example they could use a base map and share information they have. Some information they want to collect and give out to public is perfectly fit for OSM (say max speeds) while others are purely their thing which should not go to main OSM database (say information like which community a specific house belongs to). (So they want to share all information with public, but some information should be captured on a separate storage/db) They would like to have a separate layer to hold such non-OSM information. This would keep OSM database clean and it would allow government to take responsibility for quality assurance and updates of that data. How should this be implemented? Separate osm database (with data of those additional layers only) and then different editors could be used to fill that database by pointing to api url of this extra server? If I need more layers, more databases have to be created etc.? (presentation part of mapnik/openlayers is clear) I was looking for information about this on osm wiki but didn't find anything useful so maybe you can give me some urls/keywords where I can read about it?

Re: [OSM-dev] Possible GSoC project: tag/area monitoring service
First, a longstanding wishlist item for OSM has been data tiles, that is the API data, split into preset sized areas (eg z14), which a client could call. This may not seem reelvant to your project but you'll see why it is soon. This was actually part of my original motivation for proposing this project -- in my 2010 GSoC project, I used bbox queries to load data in tile-like sections, but as I mentioned this turned out to be very slow. Data tiles seem like they could speed things up for that sort of use. Ideally, the work involved in accessing a data tile would be comparable to accessing an image tile. Also, it seems easier to cache data addressed by tile than it is to cache the results of arbitrary bbox queries. I'd also be interested in working on data tiles -- is that in itself a reasonable project idea? My hope is that if either of these ideas are things people have been wanting for a while, they'll want to use them, and that if a project has people using it, it would be more likely to be around after the summer. One thing I was wondering about -- how do you choose a tile size to minimize both the number of accesses (larger tiles) and the byte size of tiles (smaller tiles)? Some areas have a much higher density of data than others. Perhaps some kind of quadtree-type approach could be used, where tiles are split if they have high density? The ideas you suggest for streaming-type updates on data tiles are very interesting. If you were writing an editor, you could be more certain that you were displaying the most recent data without having to reload all of it. While you could use Changepipe to make arbitrary polygons and then stream the changes, IMHO this is not as generally useful as one might imagine. Network hiccups alone can mean that it's possible to miss an event. And arbitrary polygons become complicated as the number of queues can be large. I hadn't thought about using arbitrary polygons to specify areas as it seemed too complex -- would there be much call for that? I assume the use cases would be things like keeping track of updates to a city (the area of which isn't always conveniently specified as a bounding box). By splitting the areas up, you can now take a changeset and know which areas (tile) it effects. And then each client can simply subscribe to an area (tile). You've greatly simplified the problem, whether you allow for arbitrary shapes (one shape - many tiles) or 1:1 tiles to connections. Now, to your original question... Another advantage of tiling the data is you can easily do both. Each tile can have a list of changes associated with it. If you tried to do this on arbitrary polygons, it'd get difficult very quickly. This makes sense, as I guess it means there are fewer bins to put things in when an update needs to be sent out to clients. (You only have to do the work once if several clients are looking at a particular tile.) And, if a client really did want to look at an arbitrary polygon, maybe it could rasterize the polygon into a list of tiles. For people who are interested in updates to tags, a similar approach could be used, perhaps -- in that case I guess a tile would be analogous to a particular value or set of values for a tag. -- Michael ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
Re: [OSM-dev] Info request on: additional GIS layers
Am 06.03.12 21:20, schrieb Tomas Straupis: Hello Some governmental institutions are willing to use OSM software stack and share their information. For example they could use a base map and share information they have. Some information they want to collect and give out to public is perfectly fit for OSM (say max speeds) while others are purely their thing which should not go to main OSM database (say information like which community a specific house belongs to). (So they want to share all information with public, but some information should be captured on a separate storage/db) They would like to have a separate layer to hold such non-OSM information. This would keep OSM database clean and it would allow government to take responsibility for quality assurance and updates of that data. This is a point which breaks the idea: If *they* want to be responsible for the data and making updates, no other user should have access to it. OSM is a community project where evereyone is allowed to change any data. And we are worldwide, and not restricted to any adminstrative boundaries, as the governmentals. So the only way is to add a separate layer with openlayers. Or use a WMS layer with OSM data in the governmental Web-GIS.

But this would be PART of the data they provide. And that part would barely be interesting to the rest of OSM community (both in terms of filling/taking care of the data and using it). To rephrase this: they do not want to HIDE some data (they are actually happy with adding that data directly to OSM), just some data is NOT interesting to OSM (f.e. land ownership, self-government community information, problems with infrastructure, illegal structures etc.). So the only way is to add a separate layer with openlayers. Or use a WMS layer with OSM data in the governmental Web-GIS. Point is to move government GIS to OSM software stack. They would then partly use OSM main db (where data is usable for OSM) and for other specific data they could use their own server (DB). This would be kind of GIS layering. That is software/skills required would be the same (one stack, no zoo). People would have to learn to use osm and then there would simply be more than one osm :-) So both sides win: * OSM gets some additional data source (and more publicity) * government gets free software stack, provides better/more services to public etc. The part of creating separate layers (say with mapnik) and presenting them (say with openlayers) is clear. Uncertain part (for me) is just the database part because I only have a general understanding of what would be required (I guess database and something which gives API to access that database from JOSM/Mapnik etc.). Therefore my question is: where can I get more information about creating own database/api and setting up all infrastructure around it (f.e. authorisation, editors etc.). Or if there is any other approach of achieving this goal of GIS layers? Thank you -- Tomas Straupis ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

Another question is how they keep their basic database in sync with ours? If someone in OSM moves a node because he was there with his GPS unit, or a new street/house/something is build, the two databases get out-of-sync. So someone has to overlook every change in OSM, and decide if it was a beginners error or not. A lot of our POIs are placed in our database according to our street ways. If we throw away our streets and import theirs, the POIs are misplaced. I am sure the governmental GIS has more place-accurate data, but probably out-of-date at some places. Therefore my question is: where can I get more information about creating own database/api and setting up all infrastructure around it (f.e. authorisation, editors etc.). Or if there is any other approach of achieving this goal of GIS layers? I think http://wiki.openstreetmap.org/wiki/The_Rails_Port is what you are looking for. Apart form that, Mapnik can render data from different databases, and shapefiles and other sources: shape : ESRI shapefile postgis : Postgis table or query raster : Tiled or stripped TIFF gdal : GDAL supported raster dataset ogr : OGR supported vector datasource osm : Open Street Map Or they can use the UMN Mapserver to combine Data from several sources.
