Major activities:

Web
-
based interaction with datasets and models is essential f
or knowledge
development in Earth Science. We have developed a series of tools for image processing,
LiDAR and high resolution 2D interpolation, and 3D visualization for data integration
using servlet technologies.
Servlets provide a component
-
based, pla
tform
-
independent
method for building Web
-
based applications, without the performance limitations of CGI
programs.

Our image processing tool is accessible from
http://aspen.asu.edu/web
site/Geoinformatics/viewer.htm
. Through a map interface, a
user selects a satellite image footprint, and then invokes the servlet which provides
metadata about the image and permits the user to select several processing options
(visible
-
near infrared, no
rmalized difference vegetation index, short wave infrared, and
thermal infrared). These choices are bundled and sent to one of the compute nodes on
our GEON cluster where image processing is done by IDL, and the results returned with
a browse image and fu
ll resolution GEOTIFF for download. In order to track usage, we
have developed another servlet (
http://agassiz.la.asu.edu:8080/logservlet
) that logs the
images chosen, the processing options, and
privately the IP addresses of the clients. We
average 0.6 to 2.6 images processed per day.
Importantly, we see use of these images by
users outside of ASU (University of New Mexico, University of Nevada Las Vegas,
Mesa State University, Texas A&M Univers
ity, US Forest Service, NASA, University of
Arizona, Los Alamos National Laboratory, US Geological Survey, Wisconsin Charter
School, University of Nevada Reno Desert Research Institute, etc.).

Acquisition and analysis of large LiDAR (Light Distance And Ran
ging) datasets
pushes the computational limits of typical data distribution and processing systems. The
high point
-
density of LiDAR datasets makes grid interpolation difficult for most
geoscience users who lack the computing and software resources to handl
e these massive
datasets. We have developed a prototype online system that permits users to interpolate
these dense datasets (
http://agassiz.la.asu.edu:8080/lservlet
). It uses the open source GIS
so
ftware GRASS for interpolation and other grid operations. We have undertaken a major
upgrade of thise tool with the newest version of
GRASS Open Source GIS

and with
SDSC colleagues to implement a service based arc
hitecture for ultimate implementation
in Kepler. In addition, we have begun to load these data into DB2 and are working to
develop enhanced data management and sub
-
selection capability.

The Parkfield Unified Visualization Project (PUVP;
http://agassiz.la.asu.edu:8080/gservlet
) is a geospatial data repository, with the added
benefits of easy, WWW
-
driven access and an in
-
house Virtual Reality Markup Language
(VRML) generator to allow visualization of m
ultiple data sets over the web. The
geospatial data are stored and queried using
GRASS Open Source GIS
. The user selects
data via a Java web form which runs a series of Perl scripts to extract these data from the
3

GRASS database in either GRASS or ARC/ESRI format. The scripts also convert these
data into VRML directives that can be displayed using any web browser with a VRML
plugin, or on a GeoWall. This project is completely open source, and we hope will be
built u
p by contributions of both data and code by the user community. We also expect
to port the PUVP tool set to GEON application areas at Yellowstone and the Alvord
Basin in the coming year.


Additional Activities:



Arrowsmith is member of GEON Web site commit
tee



ASU had major site visit from SDSC colleagues for upgrade of ASU GEON Node
and that included the establishment of a GRASS roll for ROCKS and also we
have now set up our ASU Central (shortly will be a dedicated machine).



Arrowsmith was co
-
organizer of t
he GEON Visualization workshop held in
March 2005 (
http://www.geongrid.org/workshops/geonvis2005/
). He wrote most
of the workshop report as well.



Arrowsmith organized along with Chuck Meerte

America meeting: Denver Annual Meeting (November 7
