This post is the result of an online conversation about tidal ellipses and how to compute them in Python. We will be using the same data from previous posts.

This post contains my notes on how to use docker. The goal is to use a docker image to speedup Linux32 and Linus64 builds for the IOOS channel.

Install

OpenSUSE

sudo systemctl start docker
sudo systemctl enable docker
sudo /usr/sbin/usermod -a -G docker $USER

No sudo

sudo groupadd ...

In two previous posts (here and here) I showed how to download and plot World Ocean Atlas Data. This post is an update where we will be using the latest oceans library and the lasted Atlas database (WOA13).

First let's define a mapping function using cartopy.

Conda and binstar are changing the packaging world of Python. Conda made it easy to install re-locatable python binaries that where hard to build, while binstar provides a "Linux repository-like system" (or if you are younger than me an AppStore-like system) to host custom binaries.

Taking advantage of that IOOS ...

Recently I got a request to help with this question. I decided to create a post out of it because it is a nice example to show how to do something from start to finish. (Something that I have to do for my SWC training, but that is another story ...

Recentemente tive que re-encontrar e re-fazer algumas figuras que fiz quando ensinava Introdução à Oceanografia Física Descritiva, para evitar esse problema no futuro resolvi seguir meu próprio exemplo e colocar mais algumas das figuras que fiz online e sob licença Creative Commons

Iris has a built-in Trajectory class that is very easy to use. You have to enter the waypoints and the number of linear spaced points between them. Imagine a np.linspace for lon, lat points. Below I will demonstrate with a simple use to extract bathymetric values from ETOPO2.

Geopandas is an awesome project that brings the power of pandas to geospatial data. I am not sure if we can load GPX data directly, so for this notebook I will use a GeoJSON that I previously converted from a GPX. (In a future post I will try to write ...

Since PR #48 folium can show WMS on top its interactive maps.

In this post I will show two quick examples using oceanographic themed layers.

According to Google Analytics, my post "Dealing with spiky data", is by far the most visited on the blog. I think that the reasons are: it is one of the oldest posts, and it is a real problem that people have to deal everyday.

Recently I found an amazing series ...
