Let’s examine, then, how the well-known principles of physics and science would work (or not) on a flat Earth. Members of the Flat Earth Society and several celebrities, including Atlanta rapper B.o.B and NBA player Kyrie Irving, claim to hold such beliefs. Humans have known for thousands of years that the planet is round, yet the belief in a flat Earth refuses to die. If you subscribe to the idea of a flat Earth, then you’d believe that no such thing happened, because the sun rotates in a circle around the sky. The Earth has yet again made a revolution about the sun.
See LICENSE file for details.If Earth were flat, you’d know it, because a lot of things would work differently. This project is licensed under the terms of the MIT license. For cropping, delete all files in the directory if want to make a fresh video.
The script will skip existing files during downloading and cropping. ImageJ is a useful tool for adjusting the crop defaults. Open geoSatView.R to edit further from defaults as needed. The script can also be run from an empty directory, as long as you set that directory as R's working directory. 
The script is also a useful reference for those looking to manipulate images in R and create videos. Vector, options: Binary: 1 = create AVI video, 0 = do not create video, 2 = create using ffmpeg system call (fastest)īelow is an example output. List(), format: c(NOAA="PATH_TO_NOAA_DATA",zoomEarth="PATH_TO_zoomEarth_DATA")Ĭhar vector, options: "NOAA", "zoomEarth".
Downloading is parallelized, so output will be stored in progress.log in root directory. Videos are stored in the data_noaa or data_zoom_earth sub-directories that are created. Users can choose between NOAA or zoom.earth sources to create the video. 
Alternatively, users can download files to a separate folder by making that folder the active working directory then running source('path/to/geoSatView.R') geoSatView(). Make the working directory in R the repository root directory and type the below. Either download a zip of the repository or make a new folder and clone with git clone. The script requires ffmpeg be installed on users systems if Usage 
Then saves out a video file (default mp4) to video folder. Downloads a screenshot at 5 min intervals of the zoom.earth website centered on the West Coast of the United States. For Zoom Earth (which includes fire locations) data:. Combines the cropped images and associated timestamps into a single image and saves to data_crop folder. Crops the image (default is focused on California and the Bay Area). Downloads GOES (GEOS-16 or GEOS-17 currently) satellite data ( ) into data folder. This script performs the following actions: GeoSatView Downloads GOES (GEOS-16 or GEOS-17 currently) or Zoom Earth satellite data and makes video animation using R.
