Recent diary entries

I have updated my statistics that I generate from the ITO world comparison with the OS Locator data set. If you look at the graphs we can see an impressive decrease of unmapped roads. Unsurprisingly, a lot of districts have reached completion - with over a quarter now at 95%!

However, the addition speed of unmapped roads has decreased over the recent months. So there is still 319 days left at current speed. So, keep mapping.

Recent ITO world data shows that the current mapping speed is 665 roads/day fixed or added. Assuming that the current mapping speed is kept up, this means the complete road network will be finished in 313 days. Less than a year to go.

(100% complete == all roads from the British government Ordnance Service are present and correctly named)

POI in Germany / Europe

Posted by mannequinZOD on 9 February 2011 in English.

Hallo,

I have been monitoring POI development for Europe and Germany for fun. I use the POI exports provided by cloudmade and count some selected POI's and look at the development over time. Unfortunately, cloudmade does not provide any POI exports for Europe anymore, so new data only contains German POI development. Interestingly, there is a trend of fewer and fewer POI additions recently. It could be possible that the German community gets tired of mapping, but I don't think that this is the case. I hope my stats don't have errors, but is it possible that most POIs in well mapped areas have been mapped and we are seeing a saturation effect? This would be great news and indicates that OSM reaches a new level of maturity.

Point of Interest Statistics POI

Posted by mannequinZOD on 7 December 2009 in English.

I have assembled some POI statistics for Europe and Germany. The idea is to track development over the next couple of weeks/months. Just follow the link or go to the OSM wiki stats page.

The data comes from cloudmade's POI.gpx files and is extracted with a simple bash script. I am happy to pass it on in case someone is interested

UPDATE (7/12/09): There is an error in the calculations. It only counts POIs with names. I will update it tonight

Cleaned up more than a 100 mapping errors (only missing junction nodes) in the Cambridge, UK area, one of the 'better' mapped places. There are still plently left further outside the city.
Look at http://keepright.ipax.at/ and display all junction errors in your neighbourhoor. You will be surprised. The rendered map might look quite nice already, but it's ugly underneath
