In the recent trends, the spectro-radiometer technique has proved its significance in the development of spectral library of earth’s surface materials to support the hyperspectral image interpretation and analysis. To enhance the efficiency of hyperspectral image classification, acquisition of spectral signature must be carried out. A practical study was carried out on Muthupet mangrove forest, Tamil Nadu, India. According to remote sensing data, the selected study shows as contiguous lagoon, and Avicennia marina (95 % occupancy) is the majority community of the study area followed by Acanthus ilicifolius, and Aegiceras corniculatum. It is the first attempt to develop the spectral library for mangrove true species, and mangrove associates for the Muthupet lagoon, Tamil Nadu, India. With detailed field visits, by using the analytic spectral device (ASD), the spectral library built for prominent 6 true mangrove species such as Acanthus ilicifolius, Aegiceras corniculatum, Avicennia marina, Excoecaria agallocha, Rhizophora apiculata and Rhizophora mucronata) in connection to that 5 mangrove associates Salicornia brachiata, Sesuvium portulacastrum, Suaeda martima, Suaeda monoica, and Azims tetracantha. The reflectance and absorption of each species was observed, and built a spectral library of mangroves species. It is found that Acanthus ilicifolius provides high reflectance than others. This spectral library can be useful for mangroves species identification using hyperspectral data.

使用现场光谱仪开发印度泰米尔纳德邦穆图佩特泻湖的红树林原生物种光谱库

在最近的趋势中，分光辐射计技术已证明其在发展地球表面材料光谱库以支持高光谱图像解释和分析方面的重要意义。为了提高高光谱图像分类的效率，必须进行光谱特征的采集。在印度泰米尔纳德邦的Muthupet红树林中进行了一项实际研究。根据遥感数据，所选研究显示为连续的泻湖，Avicennia滨海区（占95％）是研究区域的主要社区，其次是Acanthus ilicifolius和Aegiceras corniculatum。这是为印度红树林真物种以及印度泰米尔纳德邦Muthupet泻湖的红树林同伴开发光谱库的首次尝试。通过使用分析光谱设备（ASD）进行详细的实地访问，为与这5种重要的6种真实红树林物种（例如Acanthus ilicifolius，Aegiceras corniculatum，Avicennia marina，Excoecaria agallocha，Rhizophora apiculata和Rhizophora mucronata）建立的光谱库红树林联营海蓬子brachiata，海马齿，碱蓬martima，碱蓬同丝水霉，和Azims tetracantha。观察每个物种的反射率和吸收率，并建立了红树林物种的光谱库。发现白can提供比其他人更高的反射率。该光谱库可用于使用高光谱数据识别红树林物种。
