Installing Sen2r on Linux Systems

This instruction shows how to install Sen2r which is an R library that helps to download and preprocess Sentinel-2 optical images.

Before installing sen2r, it is recommended to check R (v. 3.4.4 or higher) and the following libraries to be installed:

• GDAL, PROJ and GEOS (required by rgdal and rgeos);
• jq (required by jqr);
• protobuf (required by protolite);
• V8 (required by geojsonio);
• openssl (required by openssl);
• cairo (required by gdtools);
• libcurl (required by curl);
• NetCDF (required by ncdf4);
• libxml2 (required by XML).

Some external dependencies are required to run specific sen2r features:

• Sen2Cor is used to perform atmospheric correction of Sentinel-2 Level-1C products: it is required by the package, unless you choose not to correct products locally (using only Level-1C — TOA products or downloading directly Level-2A products);
• GDAL is required to smooth/bufferise a cloud mask, and can be optionally used to compute spectral indices, RGB images and thumbnails;
• aria2 is an alternative downloader which can be used to faster the download of SAFE archives; it can be optionally installed and used.

These commands should be run in the Terminal.

On Ubuntu 22.04:

sudo apt install -y r-base gdal-bin aria2 libpython2-dev libudunits2-dev libgdal-dev libjq-dev libprotobuf-dev protobuf-compiler libv8-dev libssl-dev libcairo2-dev

Older distros:

sudo apt-get install -y r-base gdal-bin python-gdal aria2 libpython-dev libudunits2-dev libgdal-dev libjq-dev libprotobuf-dev protobuf-compiler libv8-dev libssl-dev libcairo2-dev

On Ubuntu 16.04 LTS Xenial:

sudo add-apt-repository -y ppa:opencpu/jq sudo add-apt-repository -y ppa:ubuntugis/ubuntugis-unstable sudo apt-get update -q

On Debian:

sudo apt-get install -y r-base gdal-bin python-gdal aria2 libpython-dev libudunits2-dev libgdal-dev libjq-dev libprotobuf-dev protobuf-compiler libnode-dev libssl-dev libcairo2-dev proj-epsg

On Fedora:

sudo yum install R gdal gdal-python aria2 python-devels gdal-devel proj-devel geos-devel udunits2-devel jq-devel protobuf-devel v8-devel openssl-devel cairo-devel libcurl-devel netcdf-devel libxml2-devel

On ArchLinux:

sudo pacman -S — noconfirm r base-devel gcc-fortran python-gdal wget aria2 jq protobuf git cd /tmp; git clone https://aur.archlinux.org/gyp-git.git cd gyp-git; makepkg -si — noconfirm cd /tmp; git clone https://aur.archlinux.org/v8-3.14.git cd v8–3.14; makepkg -si — noconfirm cd /tmp; git clone https://aur.archlinux.org/udunits.git cd udunits; makepkg -si — noconfirm
