Aggregate raster layer to H3 grid

Creates an H3 grid covering the raster layer extent and aggregates raster values into its cells.

Inputs:

• Input raster layer. GDAL-compatible raster dataset;

• Minimal H3 Zoom (H3 zoom levels are valid in range 0-15);

• Maximal H3 Zoom (H3 zoom levels are valid in range 0-15);

• Band number - raster band to aggregate values from (leave empty to use band 1);

• Pixel spatial handling mode:

  • PIXEL_CENTER (PIXEL_CENTER) - include pixels whose centers fall inside the H3 cell;

  • INTERSECTS (INTERSECTS) - include every pixel touched by the H3 cell;

• Aggregation method. How to statistically aggregate values:

  • Create grid only (EMPTY)

  • Count (COUNT)

  • Sum (SUM)

  • Mean (MEAN)

  • Median (MEDIAN)

  • Min (MIN)

  • Max (MAX)

  • Mode (MODE)

• Output field name;

• Split zoom levels. If checked, each H3 zoom level cells will be saved in separate layer.

Outputs:

• None
