TERRA-MAR, Digital Mapping and Spatial Data Management Software
Terra-Mar specializes in Software and Systems for Satellite and Airborne Remote Sensing Mapping and Spatial Data Management applications. They have provided computers and networking equipment to support the the expedition's WWW updates and Internet connection. They have also supplied a prototype backpack video mapping system to support video documentation of expedition activities.
Oil spill mapping is the latest specially integrated airborne
system that Terra-Mar has delivered to the Marine Spill Response
Corporation. This system merges attitude GPS information, multi-
spectral video imagery and Side Looking Airborne Radar returns
into near-real-time map products to support the management of oil
spill disasters.

The company is known for its sophisticated, user friendly applications software for integrated raster image processing and geographic information systems (GIS). Terra-Mar is recognized as an important contributor to the exploding Integrated Geographic Information Systems Market.
Terra-Mar is a small business concern staffed with degreed professionals specializing in the fields of remote sensing and GIS applications. Traditionally, Terra-Mar has specialized in the geologic and exploration sciences. Today, Terra-Mar's products and services are used by numerous organizations with intensive data processing requirements for a broad range of applications including resource assessment and management, oil and minerals exploration, land use planning, disaster situation management, environmental monitoring, and intelligence operations.
TERRA-MAR'S MISSION
Terra-Mar's mission is to create the powerful spatial relational database, image mapping and interpretation tools required to meet the growing needs of the integrated geographic information systems market. Terra-Mar has built strong alliances with other key industry players worldwide - - from hardware manufacturers to software developers. It is Terra-Mar's intent to be the dominant player in the processing of spatial information for resource management and disaster scenarios.
SOFTWARE PRODUCTS AND APPLICATIONS
Workstation IDIMS and Global Data Catalog (GDC) have been used extensively by leading academic, government, research, and commercial organizations for varied applications including:
Transformation Techniques, The InterBuilding Link
Transformation Techniques, Inc. is the only manufacturer that
offers wireless LAN products from T-1 to 10 Mbps at frequencies
of 915 MHz, 2.4 Ghz, 23 GHz and 31 Ghz. They have provided a 915
Mhz, 2 Mbps wireless solution, built around AT&T WaveLAN spread
spectrum technology, to connect the expedition's base camp to the
closest Internet access point, 5 Km from camp. The system is also
being evaluated by Terra-Mar for high-speed telemetry between an
aircraft and a ground based computer for forest fire mapping
applications. This system includes peer to peer network
adapters, proprietary WaveAmp transceiver amplifiers and
directional antennas.
TTI specializes in outdoor wireless links between buildings,
including: peer to peer, bridge and repeater configurations.
Standard network management capabilities are implemented.
Spread-spectrum or microwave radio techiques are used depending
upon the data rate.

Transformation Techniques offers a broad range of wireless connectivity solutions at multiple frequencies and data rates. For this reason, we can offer products for any radio frequency environment offering wider bandwidths and frequencies to avoid interference.
Based on our philosophy of a universal platform, we have developed the following wireless products:
The InterBuilding Link T-1
The InterBuilding Link T-1 provides an economical single T-1 link between two sites using millimeter wave technology that can be used for voice or data. A standard T-1 interface is provided. Both licensed and unlicensed techniques are available.
The InterBuilding Link 2 Mbps
The InterBuilding 2 Mbps provides point to point or point to multipoint connectivity between buildings up to five miles away at a bandwidth of two mega bits per second using spread spectrum. This connectivity can be used for Ethernet LAN, Token Ring LAN, Video and Voice. A standard LAN interface is provided. Repeater configurations are supported.
The InterBuilding Link 10 Mbps
The InterBuilding 10 Mbps provides point to point connectivity between buildings up to five miles away at a bandwidth of ten mega bits per second using millimeter wave techniques. In addition, a T-1 can be added to the same link as well as a second link operating as a standby at two mega bits per second. Both licensed and unlicensed techniques are available.
Antennas, Amplifiers, Accessories
We offer a full line of antennas, amplifiers, switches and assemblies for wireless systems along with on-site support services. Many of our products are available as OEM products to wireless system manufacturers.
OUR PHILOSOPHY
At Transformation Techniques Incorporated, our focus is on outdoor wireless links. We have found that there is no one best solution for providing wireless connectivity between outdoor facilities in a campus or to nearby locations.
As technology develops or as requirements change, the actual transmission method best used for the connectivity changes. Today's spread spectrum based systems are reliable and eliminate licensing by allowing manufacturers, such as Transformation Techniques, Inc., to build very cost effective connectivity systems. Although spread spectrum systems are the current state of the art innovation, thay are not always the best technology for particular connectivity requirements since they are limited to a maximum bandwidth of 2 Mbps (megabits per second).
As a result of this need to support numerous transmission methods, we have developed a common platform, or bridge, with various interfaces that are required to transmit information over the method used. We call this platform "The InterBuilding Link". The InterBuilding Link is a family of products based on this platform. The InterBuilding Link utilizes highly sophisticated software and network management techniques, including SNMP, that support the transmission occuring over the method used, whether it is radio waves or light.
Under the radio wave category, the InterBuilding Link supports spread spectrum, microwave and several other capabilities operating at various frequencies. Because of the InterBuilding Link's unique common platform design, it will be able to quickly use new techniques as they become available. This also means that these techniques can be incorporated into previously installed systems allowing them to be upgraded as needed or as technology evolves, thereby protecting your investment long into the future.
