COMPANY PROFILE BGECO, as a local company with capability to mobilize international expertise, endeavors to become a prominent leader in providing services in the fields of ground and aerial survey, map production, vehicle tracking systems, urban planning and management, marketing of satellite imagery, GIS, MIS and IT applications. Such would contribute in a significant measure to strengthening the infrastructure of Libya. As we have a working partnerships with global companies such as MAPS and FUGRO, we provided high quality services to governmental and nongovernmental clients in the past and continue to do so. We aspire not only to expand our activity, but to also elevate the quality of our services to a world class level.

CONCEPT What? Why? How? Results?

WHAT? to KNOW the LIBYAN HERITAGE

WHAT?

WHY? The heritage resources of Libya are largely unknown. This is; a consequence of the lack of a comprehensive record of sites, monuments and significant finds, their location and nature. This makes heritage assets vulnerable to loss or change through conflicting land use and unsympathetic development. Therefore the building of a National Heritage Inventory will need to be placed at the very top of the agenda, quite simply to enable the Department to fulfill its role in Law.

LIDAR

LIDAR Applications of LIDAR Archaeology - LIDAR has many applications in the field of archaeology including aiding in the planning of field campaigns, mapping features beneath forest canopy, and providing an overview of broad, continuous features that may be indistinguishable on the ground. LIDAR can also provide archaeologists with the ability to create high-resolution digital elevation models (DEMs) of archaeological sites that can reveal micro-topography that are otherwise hidden by vegetation. LIDARderived products can be easily integrated into a Geographic Information System (GIS) for analysis and interpretation. Beyond efficiency, its ability to penetrate forest canopy has led to the discovery of features that were not distinguishable through traditional geo-spatial methods and are difficult to reach through field surveys. An April 2009 flyover of the Maya city of Caracol used LIDAR equipment to help scientists construct a 3-D map of the settlement in western Belize. The survey revealed previously unknown buildings, roads, and other features in just four days, scientists announced at the International Symposium on Archaeometry in Tampa, Florida. [1]

LIDAR

GPR (Ground Penetration Radar) What is GPR? A geophysical prospecting method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can be used in a variety of media, including rock, soil, ice, fresh water, pavements and structures. It can detect objects, changes in material, artifacts, Mapping Archeological features, cemeteries pattering and voids and cracks.
