Multiyear Spectral Analysis of the Baltic States

Overlayed in red, green and blue colour spectrum this analysis visualizes Landsat 7 and 8 band 1 data identifying man made features in the years 1999, 2008 and 2014 respectively.
The hard surfaces from the earliest dataset that later disappeared are shown in red, while green represents features from the middle of the period and blue presents the latest developments. That in white is the data that appears in all three overlayed data sets, thus showing features that are unchanged. While reading the visualization, naturally occurring surfaces such as ice or sea vegetation are also visible and identifiable after closer observation.
