[McIDAS #ZLP-298012]: Rotating Globe Movie



Hi Oana,

I got the following back from the creator of the rotating globe demo
seen at:  http://www.ssec.wisc.edu/data/composites.html

Here is what he (Rick Kohrs) had to say:

  You can start by directing the user to my paper from the 2006 AMS
  Conference:

  http://ams.confex.com/ams/pdfpapers/98509.pdf

  This will lay the ground work for creating the image. Also, McIDAS 2006
  should (has not completed testing yet) include my new application that
  combines the images (IMGRGB).

  Here's the location of the basemaps I use:

  ftp://ftp.ssec.wisc.edu/pub/mug/basemaps/

  In a nut shell, I use IMGREMAP to remap all the GEO images in to a
  rectilinear projection and use IMGOPER with FORM=CMIN to combine the
  images and to attach the correct calibration. I have been using GFS
  model data for surface temperatures.

  To create the spinning globe, I use the old trick of poking word 70
  (value = 0 to 3600000) of a meteosat-7 image:

  ftp://ftp.ssec.wisc.edu/pub/mug/basemaps/basemap.metnav.gz

  I remap the R, G and B areas created by IMGRGB into the meteosat
  projection.

  If the user is fairly McIDAS savvy, the above information should get
  them on the right track.

Rick

The "old trick of poking word 70 of a meteosat-7 image" is the same
thing that is done in the rotating globe McBASI script, GLOBLOOP.MCB,
so there is no mystery in how to rotate the globe.

The fantastic displays that Rick creates are a function of how he
combines various images with the "background" imagery (e.g., land
use images, topography, etc.).  I, for one, was happy to see Rick's
comment that the McIDAS program he wrote (IMGRGB) is scheduled to
be included in the v2006 McIDAS-X distribution.

The only thing that Rick's note did not touch on was turning the
rasters of each frame (GIF?) into a QuickTime movie.  There are,
however, undoubtedly lots of procedures out there for doing this.

Cheers,

Tom
