As the first step towards a sensor network application, we estimate water temperature of the lakes and marshes. The temperature data measured at a limited number of measuring points are used to display a preliminary result and other necessary point data for a more precise display are estimated by IDW from previously collected data which has been measured at different points. In this estimation, IDW is available as an extended function of ArcGIS software. Moreover, the water temperature distribution pattern of the whole lake is visualized by applying a color gradation to the map. In an experiment using data from nine locations over the past 10 years at lake Kamo on Sado island, the water temperature distribution patterns on the surface and at a 3m depth position in summer and winter were analyzed. Furthermore time related variations of the data during the 10 year period were also analyzed. Decisions about optimal location of temperature sensors and data sampling time intervals can be applied with greater confidence on the basis of these results.
