Simulation of Optical Remote Sensing in a Laboratory Setting
Airborne lidar bathymetry and multispectral/hyperspectral imagery are optical remote sensing techniques used to map the coastal environment. These optical remote sensing systems have been used as an alternative for the survey of large areas over short periods of time. Sensors and observers use the data collected by optical remote sensing and geographic information systems (GIS) to plot and analyze the land and waters in the coastal environment. However, the biological and chemical conditions of underwater habitats may vary widely with season or time of year, geographic location and water depth. A laboratory that can mimic these natural conditions can aid in preparation for remote sensing surveys and ground truth efforts before a physical visit to the study site that can be hundreds of miles away from the investigator’s laboratory. The experiments were conducted at UNH water tank facilities in Chase Ocean Engineering facilities, where background illumination, sea surface conditions and water clarity were simulated.
