The EIAGRID Portal
Main Objectives
Creating a grid computing environment for in-field QC and
Optimization of SR/GPR data acquisition by:

1. Providing a web-browser-based user
interface easily accessible from the field

2. On-the-fly processing of the seismic field
data using a remote GRID environment

3. Fast optimization of data analysis and
imaging parameters by parallel processing
of alternative workflows

The EIAGRID Portal
Main Objectives
Creating a data grid environment to facilitate analysis &
decision making in integrated multi-disciplinary studies by:

1. Providing a flexible and customizable
data grid management architecture
using iRODS

2. Georeferencing the data using Geo
Information System (GIS)
technologies

3. Interconnecting the different types of
data by mesh-generators and data
crossing techniques

Main Problem of SR/GPR acquisition:

Real-time processing is difficult and cost intensive

 Acquisition parameters such as recording time,
sampling interval, source strength and receiver
spacing cannot be optimized in the field

Solution:
Wireless data
transmission + remote
GRID computing facilities

Remote Grid Computing
Preprocessing and Visualization using SU:
 Basic preprocessing steps can be applied without installing
the complex SU processing package.

Imaging and RSC using CRS technology:
 Data-driven CRS imaging technology---state-of-the-art in oil
exploration---enables highly automated data processing.
 GRID deployment using high performance computing
facilities provides the necessary computing power.

Parallel processing of different workflows:
 Cumbersome sequential optimization of processing
workflow and processing parameters speeds up drastically.

Conclusions
EIAGRID
 ...minimizes the software and hardware requirements
needed to perform a successful SR/GPR data acquisition.
 ...reduces the complexity of data QC and choice of
acquisition parameter for less experienced users.
 …provides fast and accurate results by using modern
imaging technology and high performance computing.
 … facilitates the creation of an integrated geophysical
database for environmental studies.

Enables a wider use of SR/GPR surveys in environmental
and earth sciences through Grid technologies
