True Colour Classification of Natural Waters with Medium-Spectral Resolution Satellites: SeaWiFS, MODIS, MERIS and OLCI
The colours from natural waters differ markedly over the globe, depending on the water composition and illumination conditions. The space-borne "ocean colour" instruments are operational instruments designed to retrieve important water-quality indicators, based on the measurement of water leaving radiance in a limited number (5 to 10) of narrow (≈10 nm) bands. Surprisingly, the analysis of the ...
متن کاملSpectral analysis of the Forel-Ule ocean colour comparator scale
François Alphonse Forel (1890) and Willi Ule (1892) composed a colour comparator scale, with tints varying from indigo-blue to cola brown, to quantify the colour of natural waters, like seas, lakes and rivers. For each measurement, the observer compares the colour of the water above a submersed white disc (Secchi disc) with a hand-held scale of pre-defined colours. The scale can be well reprodu...
متن کاملLand Cover Classification with the Medium Resolution Imaging Spectrometer (meris)
The Medium Resolution Imaging Spectrometer (MERIS) is a payload component of Envisat-1. MERIS is operated over land with a standard 15 band setting acquiring images in the VIS and NIR part of the electromagnetic spectrum. Data are acquired at 300 m (full resolution) and 1,200 m (reduced resolution) spatial resolution over land, thus vegetation can be monitored at regional to global scales. The ...
متن کاملColour Display Strategies for Enhanced Representation of Meris Data
In this paper the problem of enhanced colour representation of MERIS data is discussed. Four methods are presented which tackle the problem of multispectral data colour visualisation. In order to assess these colour display strategies a data analysis using both statistical and information measures is presented. The performance of the proposed methods is evaluated objectively by means of mutual ...
متن کاملDimensionality Reduction for Colour Based Pixel Classification
In digital images, providing classification based on colour, hue or spectral angle is a problem usually solved by combining a variety of pre-processing steps, as well as object wise classifiers. We have developed a method for transforming colour or multispectral image data to a 1D colour histogram with respect to the digital characteristics of intensity measurements. Classification is then redu...
