I'll look into generating a large map using google maps. If it can't generate something better than the previous one, we can continue generating the old one too. -- James Treacy [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Please take a look at http://people.debian.org/~treacy/developer-locations.html I'd like to hear what others think of it. The cool thing about this is that it uses google maps so it allows you to zoom in on areas you are interested in. Notice how clustering reduces the number of markers in areas of high concentration of developers (necessary or the map is too slow). As you zoom in the density decreases and fewer markers are visible on the screen so more are displayed. In the default view, I think we have too few markers - at least in the area I could judge it, that is Europe (it really looks like we only have a few people there, whereas with the old map, you can get a good impression where the debian-dense is higher). Of course, being able to zoom in makes mistakes in the data more obvious. In particular, there are a number of people who claim to live in the water. To be fair, some of those near the coast may have entered a correct location but rounding has placed them on the wrong side of the coastline. The other issue I have is that the data is too detailed in lots of cases - one can easily spot which place exactly certain DDs live (I don't have a personal issue with this though, because I just gave the coordinates of the town I live in which isn't secret anyways).

Without clustering the map is too slow to be usable. The clustering algorithm creates a grid and uses the large marker whenever there are more than a (configurable) number of markers in a square. I'll try refining the grid a bit and upping the number per grid to see what happens. For usablility, the goal is to keep less than about 150 markers on the screen at a time.

Is this really a concern? All the public knows is that an anonymous DD lives within 1km of that spot (actually about .7km east-west at 45 deg N or S). -- James Treacy [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

One idea I had was to overlay the number of people represented by a marker to the center of the marker. I agree that clustering is a good idea. However, it might be usefull to e.g. say a cluster can at maximum be 50 (or 30?) developers or so - just to make sure we don't get too few points on parts of the map with many developers (it works quite well if one is not on the view the world-size). I think that even the first map should give you a good graphical impression of the geographically distribution of Debian. (It would become better if the clusters could be of different size depending on the numbers.) The other issue I have is that the data is too detailed in lots of cases - one can easily spot which place exactly certain DDs live (I don't have a personal issue with this though, because I just gave the coordinates of the town I live in which isn't secret anyways).

Well, I wouldn't like it for my data - but my data is inaccurate by way more anyways :)), so I don't mind too much for the map.

New Developer Locations map available
Hello web guys. I hope there are still some people here who remember me. :) Having never been keen on the Debian Developer Locations map(*), I decided it was time to create something better. Please take a look at http://people.debian.org/~treacy/developer-locations.html I'd like to hear what others think of it. The cool thing about this is that it uses google maps so it allows you to zoom in on areas you are interested in. Notice how clustering reduces the number of markers in areas of high concentration of developers (necessary or the map is too slow). As you zoom in the density decreases and fewer markers are visible on the screen so more are displayed. Of course, being able to zoom in makes mistakes in the data more obvious. In particular, there are a number of people who claim to live in the water. To be fair, some of those near the coast may have entered a correct location but rounding has placed them on the wrong side of the coastline. To help developers get their coordinates in the correct format and check to see the effect of rounding on their location I also created http://people.debian.org/~treacy/coordinate-lookup.html . I think this should be linked from the web site in http://www.debian.org/devel/developers.loc (and some of the other options for generating coordinates removed). As an aside, I think that [+-]ddd.d should be the only format mentioned for the format of coordinates. Looking through the developer coordinates, I noticed too many people make mistakes in generating or entering other formats (what does an angle of 5924 mean?). If there is interest in using this on the web site, I'd like to wait a few weeks before switching. I will be contacting developers with questionable coordinates and would like to give them a chance to fix them. A few questionable locations on the current map does not look too bad but I have found over 40 problems when using the new map. (*)I feel free to criticize the map as I originally wrote the scripts to generate it. -- James Treacy [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

As you zoom in the density decreases and fewer markers are visible on the screen so more are displayed. I like it very much, it is so cool. Personally I have been trying to do the same thing but had been stuck at the clustering problem. I've tried yours, initially markers are clustered well, but after a few zoom in and out and panning, the clustering fails to work, and then lots of red markers are shown instead, causing my browser to grind to a halt.

I'd also like developer names to be shown for the markers too, but people will start to think about the privacy issues... and currently db.debian.org doesn't report developers' coordinates to the general public, doing so may require some kind of changes...
