CERSe - Component-based Environment for Remote Sensing
This project involves construction, maintenance, and utilization of a small
(8 node) Beowulf cluster. The 8 node Beowulf is housed in the PARL
(Parallel Architecture Research Laboratory) in the Fluor Daniel Engineering
Innovation at Clemson University. We have many Beowulf clusters
in the lab. See the main PARL web page for information on what they do.
WebWulf is part of the RAC project sponsored by NASA. The cluster is used to parallelize
satellite telemetry applications and was at one point used to provide the web user a manner of
interacting with the cluster to perform requested operations. We may one day restart this project.
Some operations the user was able to do were:
- Projection into different coordinate spaces
- Precipitation calculation
- Vegetation index
- Sea surface temperature
- Phytoplankton concentration
- Ultraviolet index
- Storm tracking
- And more . . .
Each of these were performed on datasets ranging over periods perhaps as large as a year
and can be used to make MPEGs or composite images. CERSe
is the software package designed
as the main vehicle for this. Follow the link above for more information.
Products

Mosaic of NDVI, Sea Surface Temperature (Day Split Window), and
Cloud Mask - This was created using CERSe (my main research)
version 2.0 using a spotsize of 2500meters and the
equilateral map projection. The colormap was just hacked together to show the currents in the Gulf
of Mexico at the time of data aquisition. This image was produced using only 1 dataset, so is not a
composite of a collection, like others listed below.

-
Colored NDVI of Extreme Southeast USA - This was created as
a test using the next generation of CERSe. The brighter the color, the more the vegetation.
The more blue a pixel is, the less vegetation that is present there.

-
RAC-CERSe Web Query and Processing Tool (OFFLINE) - a combination of
the RAC, CERSe, and a Beowulf (WebWulf) running remote-sensing jobs using parallel
code.
- March 12th, 2000
- Sample projections produced by runs of CERSe. These are a
lot spectacular in a web browser than in an image viewer. Some are very large and may take a while to display.
- Hurricanes
- One AVHRR datafile projected using the equirectangular projection (Note the missing data which is a result of the curvature of the earth and the projection. Multiple passes of the satellite applied to the same image / projection will get rid of this)
- Southeast USA - Equirectangular projection with colormap applied
- Rain Intensity - EXTREMELY High-Res shot of Central US - upside down
