30 Days of Sphere Wrappable World Earthquake Images, as JPEGs, see today.jpg Examples of how to make interactive, 3D globes in JavaScript and ImageMagick. Links to globe projectors used in museums and exhibits. Downloads via links. Courtesy of IRIS Education & Public Outreach Generated on Thu Apr 18 12:00:01 PDT 2024 These 800K image files can be wrapped around or projected onto spheres. The circles, which represent earthquakes, will look proper after being wrapped. The file called today.jpg is the most commonly-downloaded file. Additionally you can get the 30 days leading up to today as an archive in 30days.zip Filenames for the other images are explained below. An example of how to wrap them using ImageMagick in UNIX is in the spherize.sh script. An example of an image wrapped with sphereize.sh is in the file today.sphere.jpg; (Note this is not the same as projection onto a sphere from inside of it.) Ideas for how to use images: ---------------------------- Draggable, zoomable today image (using three.js) at: https://ds.iris.edu/seismon/videoglobe/photosphere/p/today.html Draggable series of all 30 images (using jQuery and the reel plugin from http://jquery.vostrel.cz/reel) is at https://ds.iris.edu/seismon/videoglobe/reelworld.html Non-draggable image in rotation (using three.js) is at https://ds.iris.edu/seismon/videoglobe/rotate.html June 4 - 25 2014 as an animated GIF: https://ds.iris.edu/seismon/videoglobe/videoglobe_med.gif File names: ----------- eqmap[4dig year][3dig jday][2dig hour]_[4dig image#].jpg The day is from 1 to 365, and the hour is UTC time. The image# is from 1 to 30 (days) where 1 is 30 days ago and 30 is today. For example if today is Julian day 216 (Aug 4) then image 1: eqmap201421616_0001.jpg is about July 4th (Aug 4 minus 30 days) and image 30: eqmap201421616_0030.jpg is Aug 4th (today) and they were created at about 16:00 hours UTC that day. Circle colors: -------------- Red quake occurred on the day shown in the image. Yellow quake on the day previous day. Orange quake in the 5 days previous. Magenta are quakes in the past 5 years or so. For more info contact russ.welti "at" iris.edu or patrick.mcquillan "at" iris.edu
