CABAL Crimean Campaign · Last updated: 2 June 2026

CABAL is built on open data and open-source software. This page records the third parties whose work makes the Crimean campaign possible.

Terrain — Copernicus DEM

The battlefield terrain is derived from the Copernicus GLO-30 Global Digital Elevation Model (COP30), cropped to the Sebastopol–Balaklava area (44.44°N–44.82°N, 33.34°E–33.86°E) at native 1 arc-second resolution. Redistribution of the derivative heightmap is permitted under the Copernicus DEM Licence.

The modern DEM reflects post-1855 terrain. Some features (for example the Chornaya reservoir, built after the Crimean War, and minor modern cuts and fills near Sebastopol and Balaklava) are noted rather than corrected.

Feature positions

Feature coordinates (bastions, redoubts, camps, and the like) derive from a mix of Wikidata P625 points, Wikipedia infobox coordinates, OSM/Mapcarta, and inference from battle narratives. Each feature’s positional precision is tagged in the source as high (<50 m), medium (~50–200 m), or low (200–500 m inference).
