There are some holes in provinces and regions.

• Piemonte, Lombardia, Veneto, Campania, Puglia

Provinces:

• Treviso, Belluno, Vicenza,
• Milano, Varese, Bergamo/Lecco
• Alessandria
• Napoli (Capri/Anacapri)

Probably some areas were not assigned codes correctly at the source.

Almost all of the municipalities have changed after 2019-01-01, and the SHP file at ISTAT does not contain the geographic coordinates.

Torre de'Busi has gone through some changes BG -> LC -> BG, and this could have confused the algorithm.

[guglielmo]

Torre de' Busi has a wrong identifier (missing a zero-pad) in the istat SHP source file.

A solution is to modify the algorithm, forcing the 0-padding, with zfill(6), while reading metadata from the SHP file.

All other missing geometries are due to municipalities fusions happened after 2019-01-01, and are resolved by a management task in OPDM, which will generate the geometries, by uniting the geometries of the old municipalities.
