Shipping traffic
In this blog post, I demonstrate how to visualize shipping traffic data using R. The tutorial covers downloading the dataset from EMODnet, performing exploratory data analysis, and creating a map using ggplot2.
Light pollution
In this month's post, I’ll show you how to create a map using radiance data, often associated with light pollution, collected by the Visible Infrared Imaging Radiometer Suite (VIIRS).
Sea surface temperature
In this blog post, I walk you through the process of visualizing sea surface temperature in R. From downloading the dataset to reading it and creating a map using ggplot.
Fishing effort
In this blog post, I walk you through the process of visualizing Global Fishing Watch data in R, covering from downloading the dataset to reading it and creating a map using ggplot.
Distance to coast
In this blog post, I share a step-by-step guide on how to use raster data from distance to the coast. I walk you through the steps I used using the North German Sea as an example.
Bathymetry
Here are the steps I used for creating a bathymetric map in R. From where to download bathymetric data to how to read it and plot it in R.
