Mapping Ice-Mass Recession

I’ve been working on a number of small projects recently, mostly related to cartography. I recently produced an ice-mass recession map of the Columbia Glacier area in Washington state. With this map, I explored ways to depict the loss of ice-mass over time. The ice-mass data in this map was obtained by classifying and digitizing Landsat satellite imagery. Landsat images of this area became available in 1984. The red polygons in the map show the approximate extent of ice mass on August 4, 1984. The light blue polygons show the approximate extent of ice mass on August 5, 2019. In future maps, I will include charts of recession over time with respect to unit of area.
