Objects changed ? An object is a single OSM map element — a node, way, or relation (a point, a road/building outline, or a group of other elements). This counts how many objects were added, modified, or deleted across changesets — a rough measure of actual mapping work, since one changeset can touch anywhere from 1 to 10,000 objects.

What was changed ? Each changed object, from OpenStreetMap's replication diffs: whether it was created, modified or deleted, whether it's a node (a point), a way (a line or outline) or a relation (a group), and its feature, the main tag it carries (building, highway, …). Objects count on their changeset's day, so the totals match "Objects changed" above.

Created, Modified, Deleted

Objects changed by what was done to them. Click a point to see who and which changesets are behind it

Nodes, Ways, Relations

Objects changed by type; most nodes are the points that shape ways. Click a point to see who and which changesets are behind it

Top Features

Objects created or modified, by their main tag

Features Over Time

Objects changed for the 6 top features (untagged nodes and deletes left out). Click a point to see who and which changesets are behind it

Most Edited Objects last week

Objects with the most edits over the last 7 days, whatever the date range above (other filters apply). An edit is a new version of an existing object, so creating one doesn't count, and reshaping a way counts on the nodes that moved, not on the way

Changeset size ? A changeset's size is the number of objects it changed. Most changesets are tiny (one tag fix, one StreetComplete answer), while a few (imports, bots, mass edits) change thousands of objects each. The median and percentiles describe the typical changeset; the average is pulled up by the few large ones.

Size Distribution

Share of changesets and share of objects changed, by changeset size (objects per changeset)

Size Over Time

Median (p50), p75, p90 and p95 changeset size per day, log scale

Size by Editor

Bar = middle half of changesets (p25–p75), dot = median, log scale. Top 10 editors by changesets. Click to filter by editor

Largest changesets ? The individual changesets that changed the most objects: imports, bots and other mass edits.

Most Objects Changed

The 20 largest changesets of the range by objects changed (OSM caps a changeset at 10,000)

Who changes the most objects ? Rankings by objects changed rather than by number of changesets: one large import can outweigh thousands of small edits.
