OpenStreetMap Node Density Visualized
Pubblicato da tyr_asd il 27 giugno 2013 in English. Ultimo aggiornamento il 15 gennaio 2023.I’ve visualized OpenStreetMap’s node density from Frederik’s analysis of densely mapped locations:
(click for uncropped image - 8192x8192, ~1MB)
Every pixel stands for a single zoom-level 13 tile. The color represents the total number of nodes in that tile. Tiles with less than 1000 nodes are not displayed. A “low-res” version of this visualization is also available, which is based on zoom-level 10 tiles: (click to enlarge)

How-To
In case anyone is wondering how these were made: I’ve used gnuplot to create the maps, after converting the source data with a simple sed-command. Read more about the actual steps and gnuplot-commands.
Slippy Map Version
There is also a slippy map version (updated yearly)! Check it out. ;)

Thanks! Looks like a to be featured image to me.

Good job.
Before reading the text, the first thing that this made me think of is the “Earth Lights” image from NASA: http://visibleearth.nasa.gov/view.php?id=55167 . Comparing the two shows that the number of nodes does not necessarily correlate with the amount of light produced.

Thank you for those images! They are now featured on our wiki main page this week.

Awesome! Could you make a tileset (only low zooms..) like the one by MapBox on the geotagged tweets? http://www.mapbox.com/blog/visualizing-3-billion-tweets/

Very good idea! Here you go: http://tyrasd.github.io/osm-node-density/

hi, can you help me with: “convert to simple, gnuplot-readable text format” but from windows? sed-command works in windows console? if yes, how add way to file file.13 ? thanks
Commento di tyr_asd il 17 giugno 2014 alle 14:06
max1e, yes, you should be able to install and run sed also on Windows (ask google). This visualization is done only for nodes because the raw data analysis was done (by Frederik Ramm, username: woodpeck) only for nodes. If you want also ways, you’d have to repeat the analysis step, which could be a quite extensive task, I suppose…

tyr_asd, can you show me screenshot or attach file (any image hosting, or file hosting) - view of tiles.13.txt inside? (Structure) because i dont understand what done function “s/([0-9]) z=([0-9]) x=([0-9]) y=([0-9])/\3 \4 \1/’”
In windows SED - renamed file from tiles13 to files13.txt, but file inside are empty. thanks

maybe anybody need this for win

max1e, sure, I’ll send you a personal message!

Is there a newer version since 2020 available? …I am just curious how the entries evolved.

@KyZEN: The slippy map version on https://tyrasd.github.io/osm-node-density/ is updated yearly (the last update was in June/July 2022). To compare different years, use the layer selector on the top right of the page.
