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. That location differs between conda and Linux native installations, so:

With conda:

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

For Linux native:

cd /usr/local
sudo ln -s  ~/adcpcode/topog .
cd
