sits_roi_to_mgrs: Given a ROI, find MGRS tiles intersecting it.

In sits: Satellite Image Time Series Analysis for Earth Observation Data Cubes

Given a ROI, find MGRS tiles intersecting it.

Description

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.
