An interactive imagery viewer web app for the GOES satellites, widely used in meteorology for the Americas. Written in R language.
For now, in this app you can download GOES-16 data from the CPTEC/INPE FTP. This data can be viewed and animated in any selected area of Latin America (you can set latitude/longitude limits) and for any of the sixteen GOES-16 channels. You can select a date range and which hours and minutes you want to see. The images are downloaded "on the fly" as you request each image to show up but you can also download it before using the Viewer, in the Download Data tab. Also, if you want to use this data elsewhere, you can just use this secondary tab. The animation might take a while to run the first time, but as it is cached it will be faster in the following ones. And finally, each plot you make can be saved right-clicking it and clicking in "Save Image As...".
(color palette from older CPTEC/INPE images)
To use this app you need to have R and RStudio in your computer (you can also try to copy and paste the scripts in Google Colab or similar but it wasn't tested yet) as well as the packages listed bellow.
You can find all app versions in the Tags tab, where you can download them zipped. You can also right-click in the Code green tab and download it from there, or also clone the repository in your computer (if you are familiar with Git).
Some R packages were used to build this app (the most important one being Shiny, responsible for the entire page layout). You can download them executing the following code in your R console:
install.packages("shiny")
install.packages("tidyverse")
install.packages("lubridate")
install.packages("RCurl")
install.packages("ncdf4")
install.packages("raster")
install.packages("fields")
install.packages("maps")
After installing R, RStudio and all packages and downloading (and unzipping) the app, you should open app.R file in RStudio (Make sure all files and folders that follow app.R are in the same directory as app.R). A green arrow followed by Run App button will be located on the right upper corner of the first panel. You can just click on it or also selecting the entire text script (Ctrl+A) and pressing Ctrl+Enter.
Is there any tool or feature you would like to see in this app? (even if it's already on the list bellow). Found a bug? Fell free to make suggestions and contributions, in English ou em português, in the Issues tab (or make a Pull Request). You can also email me at rodrigo.lustosa.repositorios@gmail.com.
