Tropical Information System - Its Communications and Applications

The Department of Mapping and Surveying (DMS), the Australian Key Centre in Land Information Studies (AKCLIS), the Department of Industry Development (DID) and the State Government Computer Centre (SGCC) are testing a regional information network in northern Queensland. Several study sites have been chosen by different groups of participants. The members of each common-interest group share their data for the site. They can also access datasets supplied by other organisations that are not directly involved in the particular study being undertaken. The participants include state government departments, local authorities, fed- eral organisations and the private sector. The participants communicate with computer systems in Brisbane via Q-Net. Q-Net is a pilot State government tele- communications network, established by the Department of Industry Development. Q-Net uses the communications sat- ellite AUSSAT 1 as the primary instrument of data transfer. The Q-Net network is a star system, with a Master Earth Station in Brisbane acting as a hub for radial earth stations, located throughout Queensland.
