Getting the full picture: Assessing the complementarity of citizen science and agency monitoring data
Fig 3
Overlap in grid cells sampled by the EA and FWW, where complete overlap (red) represents grid cells where both EA and FWW samples are represented by all the seasons, partial overlap (yellow) represents grid cells where EA and FWW are represented by samples collected in some of the same seasons, and no overlap (blue) represents grid cells where none of the same seasons are represented by the two datasets.
Grid-cells where spatiotemporal gaps are filled by FWW samples (areas where FWW citizen scientists collected samples for all the seasons, but the EA did not) are represented by a black outline. The time period investigated is between spring 2013 and winter 2015.
