| Abstract |
| Continuous measurement and monitoring of precipitation is very important for Thailand. Accurate, timely information on rainfall location and intensity is necessary to predict and respond to droughts and floods, to predict landslides and to guide cloud seeding activities.
Thailand has approximately twenty weather radar installations in various locations throughout the country. However, it is difficult to integrate regional information into a national perspective, since each radar site covers a radius of only 240 km around the station, and different stations produce plots of different types with different geographic and measurement scales. This paper reports on our work using image processing to extract rainfall intensity measurements from the graphical products supplied by the radar sites, storing these measurements in a geodatabase, and then synthesizing new images that display current or historical precipitation information for any selected region in Thailand. This specialized geographic information system is both computation- and storage-intensive. Thus we have designed it to use the parallel processing capabilities of the multi-computer Thai National Grid. |
