Review the same rectangular landscape through time

Drag the year control or use the arrow keys. Every annual composite keeps obscured pixels below 5% across the displayed crop.

Inspect fields, attributes and count basis together

The canopy-height background and analytical geometry are translated to a local metre grid. Shape, scale and relative position are retained while geographic coordinates are removed.

Count basis

Only CF13 and CF17 are direct unique crown-mask counts. Other field counts use the large/small sample method described in the article.

Interpretation boundary

This analysis does not establish the legality of clearing, land ownership, supplier identity, measured crop yield, harvest or shipment history, or regulatory compliance. Field boundaries are analytical rather than cadastral, and palm totals outside CF13 and CF17 are sample-based estimates.

Methods

  • Annual Landsat composites were screened for cloud, cloud shadow, cirrus, snow, saturation and missing data; obscured pixels remain below 5% of each displayed crop.
  • Field boundaries follow low-canopy roads and are analytical rather than cadastral.
  • The canopy-height background and vectors are translated to a local metre grid; original coordinates and basemaps are not published.
  • CF13 and CF17 use direct unique palm-crown-mask counts. Counts for the other 16 fields are sample-based estimates.
