ideg.xunta.gal serves one MapServer per campaign (SIXPAC_2014 … SIXPAC_2026); the converter assumed one range ending in 2024. Older campaigns rename things: SUP_SIGPAC, then SUP_SIX/USO_SIX, and IDGEOM where DN_OID is absent.

Scrub changed code in 2023: before that it was PR (pasto arbustivo), which the base filter keeps as grazing land — 23% of features, against 1% once MT exists. Keeping it would have made every pre-2023 edition ~75% larger and the series would read as Galicia losing a quarter of its farmland in one year. Excluded before 2023.

Also: short_name was "Spain ", so items read "Spain 2026".

Thirteen editions, ~5.0M fields each, ~65M field-years. Needs #232.

ideg.xunta.gal serves one MapServer per campaign, SIXPAC_2014 through
SIXPAC_2026, where the converter assumed a range ending in 2024. The older
campaigns name the same things differently — 2014 has a RECINTO layer with
SUP_SIGPAC and no DN_OID, 2015 uses SUP_SIX and USO_SIX, 2020 has IDGEOM in
place of DN_OID — so the column names are mapped per campaign.

The one that matters for anyone reading the series: Galicia had no MT
(matorral) code before the 2023 campaign. Scrub was coded PR (pasto arbustivo),
which the base filter keeps as grazing land. PR is ~23% of features up to 2022
but only ~1% once MT exists, so keeping it would leave every pre-2023 edition
about 75% larger than 2023+, and the series would read as if Galicia lost a
quarter of its farmland in one year. It is excluded before 2023.

short_name was "Spain " with a trailing space, so every item was titled
"Spain  2026". The determination date now comes from the variant year.

Thirteen editions are built and published, ~5.0M fields each.
