SBIR Field Testing Alogorithms For The Remote Sensing of Coastal Water Quality Using Fixed-Wing Aircraft

小行星9362164 遥感用于大量的环境调查，包括水质评估。 所获得的水质数据大多来自卫星平台，其中包含使用宽带提供图像的传感器。在目前的机载传感设备以及计划用于卫星的新一代传感器中使用窄的、正确定位的光谱带将简化水质算法的制定。 如果能够开发出适用于广泛的沿海和内陆沃茨的简单、准确、可重复和敏感的算法，那么使用遥感不仅会变得更容易和更可靠，而且由于数据量的减少、集成时间的增加和图像分析的便利，也会变得更便宜和快捷。 监测水质状况的遥感“业务化”将更加接近现实。 在目前的调查中，算法表示光谱能量从单一的带宽，带宽的比率，和线高度发现是高度相关的叶绿素a，浊度和悬浮固体的内陆沃茨将在两个沿海生态系统，印度河泻湖和坦帕湾进行测试。它 看起来很有希望，即使在没有精确的光学特性的环境下，它也有可能从以前的地面真实情况中模拟出该环境，并推导出固定翼运输系数。

9362164 DIERBERG Remote sensing is used in a large number of environmental investigations, including water quality assessments. Most of the data acquired for water quality are from satellite platforms, which contain sensors that provide images using wide bandwidths. The use of narrow, correctly positioned, spectral bands in current airborne sensing devices as well as in a new generation of sensors planned for satellites will simplify formulation of water quality algorithms. If simple, accurate, reproducible and sensitive algorithms applicable to a wide range of coastal and inland waters can be developed, then using remote sensing will become not only easier and more reliable, but also more affordable and rapid due to the reduction of data volume, increased integration times, and facilitated image analysis. The "operationalization" of remote sensing for monitoring water quality conditions will become closer to reality. In the present investigation, algorithms representing spectral energy from single bandwidths, ratios of bandwidths, and line heights found to be highly correlated with chlorophyll a, turbidity, and suspended solids for inland waters will be tested in tow coastal ecosystems, the Indian River Lagoon and Tampa Bay. It looks promising that even in the absence of precise optical characteristics for an environment, it may be possible to simulate that environment from previous ground truthing and derive fixed- wing transportable coefficients.
