Most of radio observatories are located in isolated areas. Since radio sources from the universe is very weak, astronomer need to prepared to avoid radio frequency interference (RFI) from active spectrum users and radio noise produced by human made (telecommunication, mobile phone, microwave user etc. There are many observatories around the world are surrounded by a Radio Quiet Zone (RQZ), which is it was set up using public or stale laws. A Radio Quiet Zone normally consists of two areas: an exclusive area in which totally radio emissions are forbidden, with restrictions for residents and business developments, and a larger (radius up t o 100 km above) coordination area where the power of radio transmission limits to threshold levels. Geographical Information System (GIS) can be used as a powerful too in mapping large areas with varying Radio Quite Zone (RQZ) profiles. In this paper, we report the initial testing of the usage of this system in order to 1dentify the areas were suitable for Radio Quite Zone. Among the important parameters used to develop the database for our GIS are information on telecommunication (mobile phone) transmitters, road networks (highway), and contour. We will also use other information gathered from on-site RFI level measurements on selected 'best' areas generated by the GIS. The intention is to find the best site for the purpose of establishing first radio quite zone for radio telescope in Malaysia.
