Complete LiDAR
Workflow
1. Survey
3. Interpolate / Grid
USGS Coastal & Marine
2. Point Cloud
x, y, z, …
4. Analyze / “Do Science”
The Vision:
•
Utilize
cyberinfrastructure
developed by GEON
to offer online data
distribution, DEM
generation, and
analysis of large
LiDAR datasets.
•
Completely internetbased workflow:
– Point cloud to
visualization
•
Utilize modular web
services to complete
a variety of
processing and
analysis tasks.
•
Offer users control
of processing and
analysis parameters.

The PaleoIntegration Project (PIP) is facilitating
interoperability between global-scale fossil and
sedimentary rock databases, enabling a greater
understanding of the life, geography and climate of
our planet throughout the Phanerozoic.

How?
3-tier architecture:
Front - user interface (computer terminal, user-friendly search terms and tools)
Back - databases (schema, ontology coding - age, geography, content)
Middleware - translates user-selected parameters for database searches
- keeps track of user selections (workflow), so a modified search doesn’t mean “starting over”
- routes user requests to different software components (e.g. data query, spatial data
conversion), bringing results from multiple databases and tools together on one screen
SYNSEIS: A grid application in GEON
• SYNSEIS is a SYNthetic SEISmogram
calculation tool built as part of the
GEON system
• Uses E3D in the background
• Enables 2D and 3D seismic waveform
simulations using a service-oriented
architecture
• Utilizes both local as well as national
computational platforms such as
TeraGrid
• Integrated with GEON resources
allowing utilization of archival and
storage resources
