| Description |
Maintained by the Head Office of Geodesy and Cartography (GUGiK) under the 2021 national topographic database specifications (schemat2021), the official Baza Danych Obiektów Topograficznych (BDOT10k) — Budowle hydrotechniczne dataset provides a detailed 1:10,000 scale vector inventory of Poland's water-control infrastructure. It maps critical hydrotechnical barriers—including dams, weirs, flood embankments, locks, quays, and breakwaters—across the country, dividing spatial geometries cleanly into polygonal area features (OT_BUHD_A.gpkg) and linear structures (OT_BUHD_L.gpkg) to support regional flood modeling and national spatial data infrastructure. |
