Validate Days Requested Align With Collection

Source: R/read_smips.R
dot-check_collection_agreement.Rd

SMIPS daily COGs are published from 2015-11-20 (the earliest archived national mosaic on the TERN portal) up to approximately seven days before today. Requests outside that window return HTTP 404 from the GDAL vsicurl driver, which surfaces as an opaque "file does not exist" error from terra::rast(). This helper catches that case before any network I/O.

Usage

.check_collection_agreement(.collection, .day)

Arguments

.collection

The user-supplied SMIPS collection being asked for.

.day

The user-supplied date being asked for.
