Active tectonics, Digital Elevation Model analysis, and remote sensing

in GEON

PI Meeting update

J Ramón Arrowsmith Department of Geological Sciences, Arizona State University, [email protected] http://activetectonics.la.asu.edu/GEONatASU/index.htm

http://www.geoinformaticsnetwork.org/swgeonet/ With Jeff Conner, Chris Crosby, and Gilead Wurman


Activities

• SCEC workshop– SCEC CME/GEON

• Servlets– ASTER satellite image processing

(imsservlet)– Lidar processing (lservlet)– Visualization (gservlet)– Logging (logservlet)


SCEC-CME/GEON ties

Workflow construction: Bertram and Yolanda are in touch, but the geoscience level is not as involved

GIS (SCEC is weak there, but the community needs it)Resources in GEON are available as services; GMT vs. GIS. Could be

good to have a goal for interoperability at AGU. ARCIMS gmt arcgrid ascii format send it the file and get a color image back. Shapefiles send to dynamic arcims session back. Base data for SOCAL.

Visualization: LA3D/SCEC VIDEO spherical coordinate system with no fixed reference point Alpha stage; GEON is weak there USR. Vis workshop in January. Could tie with IDV guys for VIDEO.

USR for the greater rockies. How do we build a model for it? What are the difficulties? Should extrude the QFAULTS data

PHIL: Can we put the systems together in a some way for the geological geophysical communities: look at the strengths

CIG - codeCME - modelsGEON – dataEarthscope – has all the data flowingMeta system that takes advantage of all of the projects. Issue of open source: companies have scec or geon buy a site license? User

community has access to that software. Would publicize the software for a larger community.

Servlet questions/issues

• Vs. webservice?

• Common technologies

• Load balancing (locally and on the grid)

• Portal implementation (local/main GEON)


GRASS-based LiDAR processing webservice

Subset of Airborne Laser Swath Mapping (ALSM aka LiDAR) data from Oct. 16, 1999 Hector Mine earthquake (Mw 7.1) mapping.

~80,000 pts = 2.6 MB

lservlet job running on pop node~ 5.5 minutes to run 80,000 pts.


Products:


Coming soon:

- full function lservlet page with user control over various interpolation parameters (by GSA)

- Jobs running on HP cluster at SDSC (by GSA??)

- Capability to ingest and interpolate data of various projections

- Enhanced functionality – hillshade etc.

CYBERINFRASTRUCTURE FOR THE GEOSCIENCES www.geongrid.org

ASTER level-1B data have had system radiometric corrections and geometric coefficients applied and are reprojected to a given map projection.

1166 “granules” available

Connection Method• ArcIMS, Java Servlet, Manager

Program, Java Implemented Server


Logging of activities

• http://agassiz.la.asu.edu:8080/logservlet

• Also needs to be there in the portal(s)


Software/GEON Node issues-see forum posts

X-windows?• Samba is running well• Red Hat glibc libraries too old• ARCIMS:

– Raster/grids support?– Tomcat version 3 versus most-up-to-

date version 4 on nodes (we have both running)
