Calculate bin boundaries from bin number

Calculate bin boundaries from bin number

Usage

extent_from_bin(bin, NUMROWS)

Arguments

bin

bin number

NUMROWS

relevant number of L3 bin rows

Value

matrix of extent columns xmin,xmax,ymin,ymax -

Details

Bin boundaries are the xmin, xmax, ymin, ymax edge of each bin - compare to the output of lonlat_from_bin` which returns only the centre of each bin. This function previously lived in sosoc/croc where it is called bin2bounds

Examples

bins <- L3bin(NUMROWS = 12)
ex <- extent_from_bin(1:bins$totbins, 12)
plot(range(ex[,1:2]), range(ex[,3:4]), type = "n", asp = 1)
points(lonlat_from_bin(1:bins$totbins, 12), pch = "+", cex = .8)
rect(ex[,1], ex[,3], ex[,2], ex[,4])
