# Conda¶

## What is Conda¶

Conda is an open source package management system and environment management system that runs on Windows, macOS and Linux. Conda quickly installs, runs and updates packages and their dependencies. Conda easily creates, saves, loads and switches between environments on your local computer. It was created for Python programs, but it can package and distribute software for any language..

## How will we use Conda?¶

PDAL stands on the shoulders of giants. It uses GDAL, GEOS, and many other dependencies. Because of this, it is very challenging to build it yourself. We could easily burn an entire workshop learning the esoteric build mysteries of PDAL and all of its dependencies. Fortunately, Conda provides us a fully-featured known configuration to run our examples and exercises without having to suffer so much, and provides it for Windows, Linux, and macOS.

Note

Not everyone uses Conda. Another alternative to get a known configuration is to go through the workshop using docker as your platform. A previous edition of the workshop was provided as Docker, but it was found to be a bit too difficult to follow.

## Installing Conda¶

1. Copy the entire contents of your workshop USB key to a PDAL directory in your home directory (something like C:\Users\hobu\PDAL) or the equivalent for your OS. We will refer to this location for the rest of the workshop materials.

conda create --name pdalworkshop

conda activate pdalworkshop

conda install -c conda-forge pdal python-pdal gdal entwine matplotlib
