Download and install Topography files
---------------------------------------

.. NOTE:: **If you are using a prebuilt Virtual Computer, you can skip this step**


For processing, editing, and visualization we need topography
data; we will use Etopo1. As for the documentation and demo data, we will use
curl to download it::

  cd ~/adcpcode/topog
  mkdir etopo
  cd etopo
  curl -O ftp://currents.soest.hawaii.edu/pub/outgoing/etopo1_for_pycurrents.zip
  unzip etopo1_for_pycurrents.zip

We will install this in a location where the pycurrents code that uses it can
find it, but instead of moving the directory we will just point to it with a
symbolic link:


**With conda**::

  cd ~/miniconda3
  ln -s ~/adcpcode/topog .
  cd
