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.

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".
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).
