Re: [OSM-talk] Student Project Ideas?
Hi, regarding JOSM the following would be interesting: * graphical visualization of object history JOSM currently provides a very simple and crude view on an objects history. A graphical visualization would provide a more intuitive view on an objects history and the evolution of its key attributes on a timeline: - the objects weight, how it grew and shrinked in the past (with respect to number of tags or number of children like nodes and relation members) - the objects churn, i.e. how often and when it was modified - the objects ownership, i.e. who was editing the object A watch list for interesting objects (i.e. large relations) would be interesting too. * user interface for reverting individual objects to a previous version * user interface for reverting a changeset (similar to what the perl scripts currently do, but with a nice user interface) * next generation support for resolving conflicts: - classify conflicts according to type of conflict (state conflict, tag conflict, position conflict, etc.) - classify conflicts according to severity - visualization and manipulation of these conflict classes - provide functionality to select and resolve batches of conflicts with a certain type and a certain severity * detecting, visualizing and resolving map anomalies see http://josm.openstreetmap.de/ticket/4509#comment:12 Regards Karl Am 10.03.2010 09:52, schrieb Graham Jones: Hi Folks, We have submitted an application for OSM to participate in this year's Google Summer of Code, so next week the people from Google will be reviewing the application and our project ideas list to chose which organisations to include in the programme. Looking at the project ideas list (http://wiki.openstreetmap.org/wiki/GSoC_Project_Ideas_2010) I am a bit surprised that there are no suggestions for student projects on the 'core' OSM databases. The things I wondered are: * Are there any areas for development of API version 0.7 that could be turned into a project for someone to work on? * Would it be worth working on the XAPI server? We had trouble last year with them being down, so I wondered if it would be worth developing a more 'conventional' postgresql version of the server that we could start-up easily if the others fail again? I started to look at this at the time, but didn't get far because I got tied up in regular expressions rather than writing a parser myself. * Without wanting to re-open the acrimonious debate again, could we turn development of the OSM web site into a project? (would have to check the GSoC rules for this, because there might not be much 'code' involved). * How about the main editors - JOSM and Potlatch - are there any potential projects there? Please give this a bit of thought, and add any ideas to the Wiki page! If you don't have chance to do that, an email to me will do and I will add it.

Interestingly there were projects in the past such as the kornshell project mentored by Sun that actually was not about coding, but about management task to facilitate the placement of some new code. So it is not about writing C(ode) per se, anything that helps the open source development could be in the summer of code project.

Re: [OSM-talk] Student Project Ideas?
Hi I have a project: If you have nothing else just copy/paste from snip to snap and correct my bad english. ---snip--- title: It's about zooming the browser maps... The javascript map library khtmlib is a free library to display maps in browsers. It has a simple API to display map tiles at the browser window in a very fast way. Also the simple vector graphics circle, path and area are supported. The API provides a complete WGS84 cordinate system and frees programmers of thinking in screen x,y coordinates. Browsers like webkit or opera are doing this job quiet well but webkit has a bad bugs with image loading. Firefox is slow, but I'm sure it will change. To have a fast javascript browser map that can easily compete with google or bing map will be the result of this project. The way to get a fast map is benchmarking and that is this GsoC Projekt Our unit is frames per second! Most of the map libs and browsers are able to move the map in a usable or smooth way. To win a new dimension in map browsing we need the z-Axis. Also smooth rendered. A nice, responsive, smooth zoom opens a new intuitive way to explore the world. Like in video games we have a more usable map if we have more frames per second. Most of the computers have the hardware to show perfect frame rates. From javascript to the screen, there are some problems. This library has an interface to measure frames per seconds. It was used to opitimice speed while developing. the project details=== Automatic Banchmark tests: Calling the API in a loop is easy done in a for loop. Counting from 1..18 in small steps can result in a zoom and 1000 frames. o moving the map o zooming the map (o caching) Parameter: 10,100,1000,1 vektor lines, areas, circles Map size on screen Hardware! Browser (navigator.userAgent) Visual feedback: The tester should see the map and should be able to judge about the behavior of the browser. Is flickering... Some browsers are cheating. Pointer devices deliver lots of events and every event is a task. Now it's programming with parallel tasks and to have good speed, serializing is nesessary. To serialize this tasks is not easy. Firefox starts extra tasks to render images and gives a success message bevor the work is done. It can result in flickering image or speed penalty the automatic test does not recognice. API Dokumentation The API should be documented in a half automatic way. (grep this.xyyx=function in js) Collecting results: Like other browser benchmark tests, this test can be done by many users. For collecting results, there must be an AJAX feedback collector. This feedback should be generated without user action. The user must be able to add more information and send it to a central db (one click). As a result of this action, the result will be displayed on a ranking. There must also be an administrator option to delete entries. A Highscore in gameboy or what ever design! would be ok. If there are many Chrome on the top of the list, it's very likely that Chrome is the fastest browser. To prevent manipulation a simple ip based system should be ok. 1 IP == 1 Result. (ignoring proxys,...) If the test provides a faster benchmark result on this IP adress, the faster result overwrites the slower. Graphics: Display vector data on browser is not widly used because of Internet Explorer is blocking SVG. For map data it is essential. There must be a diagram that showed the framerate and the number of lines in an x,y diagram. The library: (I made this library and did put it under GPL) The library khtmlib is not perfect at all. It's buggy but fast. At least it is a prove of concept. To see it live go to: Please use Chrome 5 (faster than 4), Safari or Opera 10.50 (windows). Try to zoom on cached tiles. http://www.khtml.org/iphonemap/ Project Home: http://github.com/robotnic/khtmlib ---snap Firefox does not provide the same speed at the moment. Internet Explorer does not work at all (evt.pageX). I'm working here on a netbook and have no idea how it works in fullscreen on a 24 monitor. That's my project idea. A benchmark test for my map lib. Maybe it's also help for the programmer of this lib to make it really good. In a few days I hope to have some more documentation and I will give more informations about the khtmlib. Btw. I'm still in Phnom Penh but in a few days I will continue traveling to Laos. Bernhard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

An interesting suggestion to improve the 'History' list, which would also help the rendering process - I liked the sound of this as this is one of the few suggestions for projects involving the 'core' of OSM. The reply suggested that this was already being worked on - is the solution actually progressing, or would it be useful to see if a student was interested in looking at it? It is an opportunity to nurture someone to understand the innards of OSM? The backend technology exists and is running on the dev server - it is what drives the dupe nodes map. Work on user interfaces is ongoing. On this I did just try to look for the API 0.7 feature list, but can't find it - is anyone thinking about what the next version of the API will do, or do we think we are about there, and we are actually using 1.0? If there are features to add, then these could be potential projects? It's in the wiki somewhere but I don't think there's anything very useful or helpful there.
