Which disaster events Vantor (formerly Maxar) has released open imagery for, and how much. Counts come from the program's public STAC catalog and refresh daily; each image is one full-scene mosaic (COG), tagged pre- or post-event.

For the first post-event image, acquired is the satellite pass and
public is when it appeared in the open catalog — the day it became available.
Delivery lag runs from the event date Vantor records on the collection to that public
date. A dash means the catalog carries no usable event date, or no post-event imagery
has been released yet. The public date comes from catalog metadata; the daily tracker
also records when it first observes each image
(seen.json), independent of that metadata — a ◆
marks activations where the two disagree.
| Activation | Event date | Pre | Post | Total | First post acquired | First post public | Lag | Last release | Satellites | Catalog |

What this counts. Only imagery Vantor has actually published to the open catalog. Activation requests — including declined or announced-but-undelivered ones — have no public record, so delivered collections are a floor on activity, not the whole story.
