               Geoinformatics technology has become more useful to  various pruposes. With integration of geoinformatics  and ocean technology  we can obtain a continuous data cover a long the coast of  Thailand. Thailand is situated in the tropical monsoon belt of Southeast Asia. The South China Sea and the Andaman Sea, with a total coastline of approximately 2,600 kilometers, bound the country in the north, west and east by mountain ranges and in the south. The Gulf of Thailand is an enclosed sea in the southwestern part of the South China Sea, covering an area of approximately 350,000 km2, with an average water depth of 55 meters and a maximum of 84 meters. The Gulf is divided into two portions: the Upper Gulf and Lower Gulf. The Upper Gulf located at the innermost area is an inverted-U shape1, which has a coastline of 700 kilometers from Prachaub-Kiri-Khan Province to Rayong Province.2 The Upper Gulf is very shallow with an average depth of 15 meters, whereas the Lower Gulf includes a relatively deep part with an average depth of 55 meters.1 In coastal areas, many developments with high rates of industrialization and urbanization have taken place, thereby changing the land use pattern and deteriorating natural resources and the aquatic environment.

          Geo-Informatics Development Division aims to set up  marine information system which consist of the data from various sources such as oceanographic buoy, field measurement, satellite and other sensors. These data are  marine environment parameters including both physical and biological data  in the Gulf of Thailand and Andaman sea, for example air temperature, air pressure, wind speed & direction, water temperature, salinity, oxygen, wave height & period, current speed & direction, chlorophyll, plankton diversity, coast line change and coastal land use. In order to detect  changing and construct measures to keep this environment in good condition, continuous monitoring and data collecting is essential. Collecting data in long-term is also a key to obtain a better understanding, experience marine condition in certain area and management the sustainable exploitation of marine resources of Thailand.
