Monitoring Flooding in Thailand Using Earth Observing One in a Sensorweb

Abstract

The Earth Observing One (EO-1) mission has been a pathfinder in demonstrating autonomous operations paradigms. In 2010-2012 (and continuing), EO-1 has been supporting sensorweb operations to enable autonomous tracking of flooding in Thailand. In this approach, the Moderate Imaging Spectrometer (MODIS) is used to perform broad-scale monitoring to track flooding at the regional level (500 m/pixel) and EO-1 is autonomously tasked in response to alerts to acquire higher resolution (30 m/pixel) Advanced Land Imager (ALI) data. This data is then automatically processed to derive products such as surface water extent and volumetric water estimates. These products are then automatically pushed to relevant authorities in Thailand for use in damage estimation, relief efforts, and damage mitigation.EO-1 has served as a testbed and pathfinder to this type of sensorweb operations. Beginning with EO-1, these techniques for monitoring are being extended to other space sensors (such as Radarsat-2, Landsat, Worldview-2, TRMM) and integrated with hydrological models, and integration with in-situ sensors.Index Terms-Flooding, hydrological modeling, in-situ sensing, space-based remote sensing.

EO-1 Data Quality and Sensor Stability with Changing Orbital Precession at the End of a 16 Year Mission

“…The mission was chartered to collect and distribute ALI MS and Hyperion hyperspectral products in response to Data Acquisition Requests (DARs), which were soon established as a collaboration with the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Data Center (EDC). There were four extensions of the mission [ 8 ], during which normal operations continued and the daytime imagery were used in numerous science investigations [ 9 ] ranging from characterizing forest structure [ 10 – 12 ], water quality [ 13 , 15 ] and desert dust flows [ 16 ], to disaster monitoring activities [ 17 – 19 ]. Additionally, the nighttime imagery was greatly utilized by the volcano monitoring network [ 20 , 21 ].…”

“…The whole South Asia is vulnerable to extensive flooding. According to estimation, two hundred people have lost their lives during 2010 floods of Thailand [6]. Pakistan has been observing massive floods for many years because of daily and seasonal variation in the temperature levels.…”
