footprints(x)

Examples

# Create sample files
file1 = tempfile(fileext = ".tif")
file2 = tempfile(fileext = ".tif")
file3 = tempfile(fileext = ".tif")
r1 = landsat[,1:100, 1:100,]
r2 = landsat[,101:200, 101:200,]
r3 = landsat[,21:40, 51:120,]
write_stars(r1, file1)
write_stars(r2, file2)
write_stars(r3, file3)

# Calculate footprints
files = c(file1, file2, file3)
pol = footprints(files)
pol

# Plot
plot(pol)
