![]() delta: (numeric length 1): the increment, or cell size.offset: (numeric length 1): the start coordinate (or time) value of the first pixel (i.e., a pixel/cell boundary).to: (numeric length 1): the end index of the array.from: (numeric length 1): the start index of the array.The affine and curvilinear values are only relevant in case of raster data, indicated by dimensions to have non-NA values.Ī dimension object describes a single dimension it is a list with named elements curvilinear a boolean indicating whether a raster is a curvilinear raster (or NA).affine length 2 numeric the two affine parameters of the geotransform (or NA). ![]() dimensions length 2 character the dimension names that constitute a spatial raster (or NA).In addition to that, a dimensions object has an attribute called raster of class stars_raster, which is a named list with three elements: an attribute called dimensions with a dimensions object carrying dimension metadataĪ dimensions object is a named list of dimension elements, each describing the semantics a dimension of the data arrays (space, time, type etc).a (possibly empty) named list of arrays, each having named dimensions.
