Day 11: Arctic
This map is a fairly random one, as I have never mapped the Arctic before so had limited idea of what data were available. That said, with a bit of Google searching and the help of the ESRI Living Atlas, I put together this interactive map showing Arctic Search and Rescue Agreement zones which were provided by NGA, and median ice sheet extent change over time from ESRI.
The data were all pulled into ArcGIS Online from their hosted URL, with the interactivity built from the provided interface tools, including the time slider for ice sheet extent.
