wq_calc: Water quality calculation

In RAJohansen/waterquality: Satellite Derived Water Quality Detection Algorithms

Water quality calculation

Description

Calculates a set of water quality indices

Usage

wq_calc(terraRast, alg = "all", sat, ...)

Arguments

terraRast	Terra SpatRaster containing a satellite data
alg	Name (e.g. Am09KBBI()) or type of the algorithm ("chlorophyll", "phycocyanin", "turbidity") or "all"
sat	Name of the satellite or instrument ("worldview2", "sentinel2", "landsat8", "modis", "meris", or "OLCI")
...	Other arguments passed on to terra::rast()

Value

SpatRaster

Examples

library(terra)

# sentinel2 example
s2 = terra::rast(system.file("raster/S2_Harsha.tif", package = "waterquality"))
s2_Al10SABI = wq_calc(s2, alg = "Al10SABI", sat = "sentinel2")
s2_two_alg = wq_calc(s2, alg = c("TurbChip09NIROverGreen", "Am092Bsub"), sat = "sentinel2")

## Not run: (
s2_wq = wq_calc(s2, alg = "all", sat = "sentinel2")

# landsat8 example
l8 = terra::rast(system.file("raster/L8_Taylorsville.tif", package = "waterquality"))
l8_wq = wq_calc(s2, alg = "all", sat = "landsat8")
)
## End(Not run)
