satellite: Create a Satellite object

Description

Method to create a Satellite object.

Usage

## S3 method for class 'character':
satellite(x, meta, log)
## S3 method for class 'RasterStack':
satellite(x, meta, log)
## S3 method for class 'list':
satellite(x, meta, log)

Arguments

x

A vector of filenames (see raster::raster) or a raster::RasterStack.

meta

Optional metadata object (e.g. returned from compMetaLandsat). If x is a satellite dataset and recognised as "Landsat", then the metadata is automatically extracted from the respective meta informat

log

Optionally supply a log entry.

Value

• Satellite object

Details

A satellite object consists of three data sections: (i) a raster data section which holds the actual data values of the respective sensor bands, (ii) a metadata grid which holds meta information for each sensor band (e.g. calibration coefficients, type of sensor band etc.) and (iii) a list of log information which records the processing history of the entire dataset.

Examples

## 'character' input (i.e. filenames)
path <- system.file("extdata", package = "satellite")
files <- list.files(path, pattern = glob2rx("LC8*.tif"), full.names = TRUE)

satellite(files)

## raster::RasterStack input
satellite(l8)
