aggregate_raster_to_polygons_validation: Aggregate a raster to polygons: validation

Description

Data validation for aggregate_raster_to_polygons

Usage

aggregate_raster_to_polygons_validation(
  data_raster,
  aggregation_table,
  aggregation_cols,
  method,
  aggregated_field,
  z_dimension,
  z_dimension_name,
  weighting_raster,
  na.rm
)

Value

Errors if checks fail; silently passes if checks pass

Arguments

data_raster

terra::SpatRaster containing data to be aggregated to polygons.

aggregation_table

Aggregation table linking pixels to polygon identifiers, created using build_aggregation_table()

aggregation_cols

(character vector, default 'polygon_id') Polygon identifiers to use for aggregation.

method

(character, default 'mean') Aggregation method: one of 'mean', 'sum', 'weighted.mean', or 'weighted.sum'.

aggregated_field

(character, default 'data') Name of the aggregated raster values in the output table.

z_dimension

(vector, default NULL) If passing a data_raster with multiple layers, how should each layer be identified?

z_dimension_name

(default 'z') The field name for the "z" dimension corresponding to each layer of the data_raster.

weighting_raster

(terra::SpatRaster, default NULL) The relative weighting of each whole pixel to the overall polygon value, for example, if calculating a population-weighted mean.

na.rm

(bool, default TRUE) How to handle NA pixels in data_raster and weighting_raster.
