OSM QA tiles: historic snapshots

Historic snapshots represent the map as it was on a specific date. These files do not contain the full editing history, but instead represent each map object as it existed at a specic time in history.

Quarterly Snapshots

Generated from the full history pbf with the time-filter command of the osmium tool, snapshots of the map as it existed at the end of each quarter are made available below.

For annual snapshots, use the fourth quarter of each year. These represent the map on December 31 at 23:59.

How were these generated?

First, the data is extracted from the full planet history:

osmium time-filter --verbose --overwrite -o 2010-Q1.osm.pbf planet-history.osm.pbf 2010-04-01T00:00:00Z

Next, the pbf file was turned into geojson with minjur. Note: minjur was incorporated into the osmium tool as export

minjur --polygons --zoom=12 --nodes=dense 2010-Q1.osm.pbf

Finally, the output of the above command was piped into tippecanoe:

| tippecanoe -f -pf -pk -ps -Z12 -z12 -d20 --no-tile-stats -b0 -l osm -n 2010-Q1 -o 2010-Q1-qa-tile.mbtiles

The flags ensure the following (from the tippecanoe documentation):

-Z12 -z12 -d20 Only generate zoom 12, with the maximum detail available at that resolution.

-pf -pk -ps Don't limit tiles by size or feature count; don't simplify lines.

-b0 No buffer on the tile edges from which to duplicate next-door features.

--no-tile-statsDon't generate statistics for object attributes. (Saves time and memory).

-l osm -n 2010-Q1Name the layer "osm" and the tileset "2010-Q1".



Previous Generation Annual Snapshots

Before November 2017, annual osm-qa-tile snapshots were made available on this page. For consistency, these files are still available below, but users are cautioned to read the following description.

These snapshots include multipolygon representations of objects where possible from the minjur-mp command. This results in many objects being duplicated and existing as both LineStrings, MultiLineStrings, and/or MultiPolygons. This can be seen in the dramatic file size increases after 2012. Simply counting or aggregating feature and/or user counts in these tiles will yield overly inflated numbers because some objects are duplicated over many tiles (such as polygons representing administrative boundaries).
