vec_raster_times

Returns the ascending vector of time stamps recorded for the given
(band, level). Pixel-major files store one consolidated table; image-
major files derive the list from the per-tile time field.

A minimal columnar query engine with lazy execution on datasets
larger than RAM. Provides 'dplyr'-like verbs (filter(), select(), mutate(),
group_by(), summarise(), joins, window functions) and common aggregations
(n(), sum(), mean(), min(), max(), sd(), first(), last()) backed by a
pure C11 pull-based execution engine and a custom on-disk format ('.vtr').
Reads and writes 'GeoTIFF' (including tiled and 'BigTIFF' layouts) and a
tiled raster format ('.vec') with overview pyramids and time cubes for
larger-than-RAM raster data.
