In this page I collect a few mini projects or documents that might be interesting or useful to whoever stumbles here via Google search.
Occasionally I work with Generic Mapping Tool and -when I manage to set up everything properly- I absolutely adore it. Installing it on Ubuntu is not complicated but can be tedious if you, like me, do not work often with command line tools. So I wrote down a set of instructions to help speed up the process whenever I need a fresh install.
This little web app shows elevation and land surface temperature data along a North-South line of your choice anywhere in the world. The resulting graph can also be saved in .png form by right-clicking on it and selecting “Save image as…”. It is hosted for free on shinyapps.io, so it might become inactive if accessed too many times in a month (it is a relatively data-heavy app too, so give it some seconds to load).
I wrote it in December 2018 just to play a bit with Shiny and see its inner mechanisms. I barely updated it since then, but I think the app is quite nice and maybe can even have an educational purpose. You can find the code on my Github page.
I took a blind dive into the world of artificial terrain modeling and
I ended up using this experience to produce a dedicated R package. Meet
thintegen.
Another fun weekend project. StegosauR
is an R package that allows hide a text message into a .tiif image. This
image can be then shared over the web or via USB sticks and the stored
message can be extracted with StegosauR by whoever has the
right decoding information.
