hex_grid() describes spatial identity only: the DGGS family, hierarchy,
and orientation. Resolution belongs to cells and is supplied to
point_to_cell() or cell_cover(). Backend discovery is deliberately
separate from the grid definition.
Usage
hex_grid(
system = c("igeo7", "isea3h"),
pole_lon = 11.25,
pole_lat = 58.28252559,
azimuth = 0
)
Arguments
- system
Either "igeo7" (the equal-area Z7 default) or "isea3h"
(equal-area Z3).
- pole_lon, pole_lat, azimuth
Orientation in degrees. IGEO7 has a
canonical orientation; custom values are supported for ISEA3H.
Value
A globalhex_grid object.
Examples
hex_grid()
#> <globalhex_grid>
#> system: IGEO7
#> index: Z7
#> orientation: 11.25, 58.28252559, 0
hex_grid("isea3h")
#> <globalhex_grid>
#> system: ISEA3H
#> index: Z3
#> orientation: 11.25, 58.28252559, 0
