Monitoring red tide with satellite imagery and numerical models: A case study in the Arabian Gulf

A red tide event that occurred in August 2008 in the Arabian Gulf was monitored and assessed using satellite observations and numerical models. Satellite observations revealed the bloom extent and evolution from August 2008 to August 2009. Flow patterns of the bloom patch were confirmed by results from a HYCOM model. HYCOM data and satellite-derived sea surface temperature data further suggested that the bloom could have been initiated offshore and advected onshore by bottom Ekman layer. Analysis indicated that nutrient sources supporting the bloom included upwelling, Trichodesmium, and dust deposition while other potential sources of nutrient supply should also be considered. In order to monitor and detect red tide effectively and provide insights into its initiation and maintenance mechanisms, the integration of multiple platforms is required. The case study presented here demonstrated the benefit of combing satellite observations and numerical models for studying red tide outbreaks and dynamics.

Land-based mobile mapping system with its applictions for the Olympic Games

There is a trend for rapid spatial data capture supported by integration of multiple platforms and multiple sensors. This paper presents the principles and technologies of land-based mobile mapping systems based on an integration of remote sensing, GPS and GIS technologies. The innovations and advantages of the integrated system are described. The analytic model and error model of a mobile mapping system are proposed and the application interface of digital measurable images is also discussed. A Truemap Engine® with Plug-in and API is designed to manage a huge volume of stereo image series from a land-based mobile mapping system so that other geographic information systems (GIS) engines can freely use the sequence of stereo images. The applications of digital measurable images (DMI) as well as mobile mapping systems in the Olympic Games in Beijing, 2008 are presented.
