Given a ROI, find MGRS tiles intersecting it.

Source: R/sits_grid_systems.R
sits_roi_to_mgrs.Rd

Takes a a ROI and produces a list of MGRS tiles intersecting it

Usage

sits_roi_to_mgrs(roi)

Arguments

roi

Valid ROI to use in other SITS functions

Value

tiles Character vector with names of MGRS tiles

Note

To define a roi use one of:

  • A path to a shapefile with polygons;

  • A sfc or sf object from sf package;

  • A SpatExtent object from terra package;

  • A named vector ("lon_min", "lat_min", "lon_max", "lat_max") in WGS84;

  • A named vector ("xmin", "xmax", "ymin", "ymax") with XY coordinates.

Defining a region of interest using SpatExtent or XY values not in WGS84 requires the crs parameter to be specified.
