Uncompact Hex Cells

Expands compacted cells to a target resolution. All cells in the output share the same resolution.

Usage

hex_uncompact(cell_ids, grid, target_resolution)

Arguments

cell_ids

Character vector of (possibly mixed-resolution) cell IDs.

grid

A HexGridInfo object specifying the grid.

target_resolution

Integer. The resolution to expand all cells to.

Value

A character vector of cell IDs, all at target_resolution.

Details

H3 backend: Uses the vendored H3 uncompactCells function.

ISEA backend (aperture 7, Z7 index): Appends digits 0-6 to expand each cell to its 7 children, repeating until the target resolution is reached.

Examples

# \donttest{
g <- hex_grid(resolution = 3, type = "h3")
parent <- "832830fffffffff"
hex_uncompact(parent, g, target_resolution = 4L)
# }
