get_etp: Extract evapotranspiration data of Modis

In botbarja/test_list: InnovaLab Toolkit

Description

A function that extract a ETP time series of MODIS

Usage

get_etp(to, from, by, band, region, fun = "count")

Arguments

to, from	the starting and final range of date.
by	two types of increment of the sequence by month and year.
band	name of band.
region	region and object sf.
fun	function for extract statistic zonal ('count','kurtosis','max','mean','median','min','mode','percentile','std','sum','variance','first').

Details

Name of some bands.

• ETP: Total evapotranspiration.

• LE: Average latent heat flux.

• PET: Total potential evapotranspiration.

• PLE: Average potential latent heat flux.

• ET_QC: Evapotranspiration quality control flags

Value

a sf object with the new variables.

Examples

## Not run: 

library(tidyverse)
library(rgee)
library(lis)
library(sf)
ee_Initialize()

# 1. Reading a sf object
region <- import_db("Peru_shp")
region_ee <- pol_as_ee(region, simplify = 1000)

# 2. Extracting climate information
data <- region_ee %>% get_etp(
  to = "2001-02-01", from = "2002-12-31",
  by = "month", band = "tmmx", fun = "max"
)
