Appellations on the map

Appellation borders are not published as open data: for zones without an outline the dot marks the village or locality the name comes from, and its size shows how many wines of the zone are in the catalogue. Twenty-eight zones have outlines. Twenty-six are traced from the maps in the zones' current specifications published by the National Wine Agency: the maps carry a coordinate grid, georeferencing relies on it, and accuracy ranges from ten to a hundred metres depending on the map's resolution. For Bolnisi and Okami the specification map shows the municipality itself, so its border is taken from OpenStreetMap. Kotekhi is traced from the map in the Sakpatenti bulletin “Appellations of Origin of Georgian Wine” (2010), georeferenced on OpenStreetMap villages and accurate to a few hundred metres. Khvanchkara is traced from the Georgian Wine Club regional map (“Georgian Wine Infographics”), georeferenced on fourteen villages and accurate to about a kilometre. These are illustrations to the zone specifications, not legal boundaries; zones legitimately overlap — Mukuzani covers Akhasheni and Vazisubani. The sand colour is Racha's viticultural district from the Georgian Wine Club map; the pale backdrop shows the winegrowing zones traced from the National Wine Agency map.
