Acoustic Multi-Source Sensors Aid Geospatial Situational Awareness

Details: 10 December 2010 | By Kevin Corbley | 2847

Terra_Echos In the arena of covert intelligence and surveillance, a key aspect of protecting critical infrastructure and securing vulnerable borders is to identify a potential threat before it knows it has been detected. This shifts the element of surprise in favor of the responders, who can neutralize the threat before it has a chance to inflict damage. Moreover, an accurate identification of the threat ensures the level of response will be adequate.

The Evolution of a Mega City: The Case of Ibadan, Nigeria

Details: 24 November 2010 | By David T. Afolayan | 3791

The growth of mega-cities around the world poses unique challenges for managing infrastructure, health, communities and transportation. This expansion is near impossible to understand and plan for appropriately without the assistance of spatial information and geospatial technology. Geographic informatiom systems (GIS) and computer-aided design (CAD) are both helping to address these challenges. Yet, other areas that require attention fall more directly to spatial data infrastructures (SDI) and helping to build capacity within policy bodies.

BIM for Geo-Analysis (BIM4GeoA)

Details: 11 November 2010 | By I. Hijazi, M. Ehlers and S. Zlatanova | 2895

To address the challenges of sustainable management and development of the built environment, engineers and facility managers need to exploit the 3D City models which grown in recent years to include interior space. A crucial issue for facilitating interaction with these 3D city models is the ability to integrate 3D BIM into the geospatial context. This requires the use of specialized software and specific expertise. In order to simplify this process, we proposed an information system that facilitates the use of BIM for geo-analysis purposes.

Growing a GIS Garden

Details: 07 November 2010 | By Toni Jackson | 3348

Anyone with experience will tell you, gardens do not grow - no matter how talented the landscaper - without an effective growth strategy and a rich soil bed. The same can be said for planning, building and maintaining corporate data repositories - isolated databases don’t typically provide data-rich business intelligence. It’s an analogy that utility company San Antonio Water System (SAWS) understands well.

Integration of Surface and Subsurface Data Optimizes Hydrocarbon Exploration

Details: 24 October 2010 | By Raushan Kumar, Subhash Babu Ainampudi and Siva Subramanian | 4021

HydroEx_Intro The selection of effective exploration targets is an important step in achieving success in hydrocarbon exploration. As a common practice, remote sensing and GIS technology are used to prepare baseline information like geological maps, structural maps, geological cross sections, thermal anomaly detection, hydrocarbon micro-seepage identification etc. to shortlist target exploration locations. Integrating geological cross-sections with the sub-surface structural trends leads to the identification of prospect areas.
