River migration and forest loss in the Amazon basin

The repository contains supporting spatial data for the manuscript (under review). The Methods section detail how the data was processed and filtered.

Content:

1.     AmazonMigrationRates.zip - River migration rates of 23,000 Amazon reaches, 1985-2020. This point layer includes the migration rates for each year (where the centerlines of subsequent years were valid in a reach), the long-term average migration rates for the entire period, the number and percentage of mapped years, and the SWORD1 node ID and HydroSHEDS 2 PFAF_ID.

2.     AmazonCenterlines.zip - Amazonian river centerlines, 1984-2020. These are raster tiles of the centerlines, color-coded as in the manuscript figures.

3.     AmazonRiverDeforestation.zip - raster tiles of 2000 forest areas removed by river migration or flooding during 2001-2020.
