TerraVision System Overview

How does TerraVision Work?

The TerraVision software system uses a Geographic Information System (GIS) and a "relational database" in conjunction with "live" position data to provide reports of vessel performance such as if they are within operational limits or have breached defined parameters. These reports may be based on speed, movement, relative position or proximity, ETA, response zones, and time (before, after and duration).

TerraVision measures the behavior of vessels/vehicles against operational criteria and business rules set by the operator. If any parameter is breached by some event, it automatically responds as an alarm. The alarm may be audio, visual, printout, recorded in the database, emailed to an address, or transferred to another VMS system or may send a notification to a pager service to alert an authorised person.

Server and Client System Types

TerraVision can be configured as a Server system, located at a Control Centre with optional Client systems elsewhere on a local (LAN) or wide area network (WAN). The Server system coordinates all communications with the fishing vessels via a Land Earth Station (LES) and feed the Client system(s) with positional data and routed messages. Many of our projects use the decentralized processing approach of Client / Server architecture, to establish a centralized control station with distributed processing occurring on client VMS stations and which are vast distances from the central server.

There is little functional difference in VMS capability between a Client system and the Server system. The Client is a fully functional tracking system communicating with the Control Centre TerraVision server. Users can configure their Client system to suit their operations and is a mode of operation that we have successfully implemented in many fisheries around the world.

Common Applications:

Tracking:

  • Fleet traffic movement and operational compliance.
  • System device monitoring (ie. equipment sensor information)
  • Precise positioning and monitoring.
  • Safety and Security monitoring,
  • Search and Rescue operations.
