This blog post is a slight modification of the R package Vignette. The
VMDecomp R package is an RcppArmadillo implementation of the
Matlab Code for Variational Mode Decomposition (1- and 2-dimensional)
based on the papers,
- “Variational Mode Decomposition” by K. Dragomiretskiy and D. Zosso
in IEEE Transactions on Signal Processing, vol. 62, no. 3,
pp. 531-544, Feb.1, 2014, https://doi.org/10.1109/TSP.2013.2288675

This blog post (which is a slight modification of both package Vignettes) explains the functionality of the IceSat2R R package and shows how to use the OpenAltimetry API from within R. It consists of three parts,
- IceSat-2 Mission Orbits
- IceSat-2 Atlas Products

In this blog post I’ll explain the functionality of the PlanetNICFI R package based on a change detection use case. The official website of NICFI (Norway’s International Climate and Forest Initiative) includes all the details about the initiative against global deforestation. This initiative was also covered extensively on the web especially from the provider of the free Satellite Imagery. Users have the opportunity to download high-resolution imagery of forests globally using a simple sign up form.
To take advantage of the PlanetNICFI R package you will need also an API key which you can receive once you are registered. For more details see the Getting Started with Planet APIs website.

In this blog post I’ll explain how to use the CopernicusDEM R package based on a use case of the Movebank animal tracking data. I picked animal tracking data because there is an abundance in the Movebank archive from all over the world. In this specific vignette I’ll use data of Wolves from the northeastern Alberta and Caribou from the British Columbia (see the reference papers at the end of the blog post for more information).

This blog post explains the functionality of the fitbitViz R package. If you own any of the Fitbit activity trackers you can take advantage of this package to visualize your data using ‘ggplot2’, ‘Leaflet’ and 3-dimensionsal ‘Rayshader’ Maps. The 3-dimensional Rayshader Map requires the installation of the CopernicusDEM R package which includes the 30- and 90-meter elevation data.
You can read more about the Fitbit Web API and how to create an application to receive a token and the user-id in the README.md file of the package. In the README.md file you will find information on how to,
