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

The EIAGRID PortalMain 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


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: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.

Data-driven CRS imaging technology---state-of-the-art in oil exploration---enables highly automated data processing.

Imaging and RSC using CRS technology:

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.

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

… facilitates the creation of an integrated geophysical database for environmental studies.

Thank you for your attention…
