Topographic contours of Signy Island (March 2015)

Topographic contours of Signy Island with 10 m intervals, derived from a digital elevation model originally created using stereoscopic photogrammetry from VHR (very high resolution) In-Track stereo satellite imagery collected during March 2015. The topographic contours were created to support the updated release of the British Antarctic Survey (BAS) Signy Island map (BAS, 2024). The dataset is available as a polyline shapefile and a GeoPackage. WorldView-3 satellite images © 2015 Maxar Technologies.
