Context
The xcube software package was created for the purpose of producing, altering, examining, and sharing datacubes derived from Earth observation data. This guide aims to describe the procedure for installing and configuring xcube (and its applications) on Ubuntu 20.04.
Install xcube on Ubuntu from script
Set up a conda environment
There are several methods to install xcube, the main one being via Mamba or Conda. Since Conda could be extremely slow, Mamba is generally preferred. Mamba is a dramatically faster drop-in replacement for Conda and can be installed using conda itself.
The first step consists in updating the local apt package index:
sudo apt-get update -y
Next, create a miniconda3 directory:
mkdir -p ~/miniconda3
Download bash script to install conda with wget. After, execute the bash script:
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh
bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
And add the following PATH variable:
export PATH=$PATH:/root/miniconda3/bin
Initialize conda:
~/miniconda3/bin/conda init bash
~/miniconda3/bin/conda init zsh
Source the conda script to enable conda command in the current shell:
>>. ./miniconda3/etc/profile.d/conda.sh
Once Miniconda is installed, use the conda command to create a conda environment called xcube_env and install Python (>=3.9):
conda create -n xcube_env python=3.9 -y
Once installed, you can activate the environment:
conda activate xcube_env
Use conda to install mamba:
conda install -c conda-forge mamba -y
Install xcube into the environment
Finally, it is possible to install xcube from its conda-forge package. Starting from version 1 of xcube, the xcube installation automatically installs all plugins, such as the xcube viewer:
mamba install -c conda-forge xcube=1.2.0 proj=9.1.0 pyproj=3.4.1 -y
After xcube is successfully installed, you can use the package to create and visualize data cubes from Earth observation data. Examples on how to generate datacubes with xcube can be found here.
🔍 You will find some examples in our article How to use the xcube Viewer? and even more examples soon in our Jupyter Catalogue.
