# Antarctica and Southern Ocean basemap for Desktop GIS

We provide a south pole projected Antarctica and Southern Ocean basemap as a web service, which can be loaded in to Desktop GIS. 

The basemap is updated every 6 months to reflect changes to the coastline and to include updated elevation and bathymetry data, as appropriate. It is a WMTS service hosted using ArcGIS Online and is also included in the ArcGIS Living Atlas. 

This guide will run through [how to add it to a QGIS Project](#using-the-basemap-in-qgis).
