Automatic decompression of EE Image or EE ImageCollection objects

Description

Earth Engine apply a simply lossless compression technique: IMG_Float_Values = scale * IMG_Integer_Values + offset. ee$Image$scaleAndOffset or ee$ImageCollection$scaleAndOffset backs the integer pixel values to float point number.

Usage

`ee$Image$Extra_scaleAndOffset(x)`

`ee$ImageCollection$Extra_scaleAndOffset(x)`

Arguments

x	An ee$Image or an ee$ImageCollection object.

Value

An ee$Image or an ee$ImageCollection with float pixel values.

Examples

## Not run: 
library(rgee)
library(rgeeExtra)

ee_Initialize()
extra_Initialize()

# Adjust first image in NASA IMERG V06 for scale and offset.
adjusted_image <- ee$ImageCollection("NASA/GPM_L3/IMERG_V06")[[1]] %>%
  ee$Image$Extra_scaleAndOffset()

# Adjust Sentinel-2 SR images for scale and offset.
adjusted_images <- ee$ImageCollection("COPERNICUS/S2_SR") %>%
  ee$ImageCollection$Extra_scaleAndOffset()
