An S4 Class for Spatio-Temporal Environmental Assessment Data

The ea_spatial class is a container for environmental assessment data that has a spatial component. It is designed to be flexible, supporting vector data via sf objects and raster data via stars or terra::SpatRaster objects.

It standardizes the data by encapsulating a spatial object in the data slot and a list of descriptive information in the meta slot.

Slots

meta

A named list containing metadata. Expected fields include data_type, region, time_descriptor, units, source_citation, and original_value_col.

data

A spatial object. Must be of class sf, stars, or SpatRaster. The object is expected to have a column or layer named value containing the primary data.
