Hyperspectral Remote Sensing of Urban Areas

Abstract: The use of airborne hyperspectral sensors for urban analysis represents a significant advance in remote sensing. The greatest challenges to effectively using urban hyperspectral imagery include (i) managing the natural spectral complexity of urban fabrics, (ii) selecting optimal feature sets from an enormous number of candidate features, (iii) designing classifiers that are minimally affected by the curse of dimensionality, and (iv) reducing the computational burden of hyperspectral algorithms on large images.… Show more

“…Especially in the past decade there has been a steady growth in the development and availability of new sensors able to better cope with the challenges outlined above. Two technologies that have made remarkable contributions are hyperspectral remote sensing, also referred to as imaging spectroscopy, and Light Detection And Ranging (LiDAR) [9][10][11]. As opposed to broadband multispectral sensors, hyperspectral sensors tend to extensively cover both the VNIR and SWIR regions with a high number (ranging from tens to hundreds) of narrowly defined spectral bands, allowing them to capture even subtle spectral features, strongly improving the ability to discriminate different materials and in some cases even material conditions [10].…”

“…Ref. [17] presented a review of latest advances made in recent years in both the technological part and with respect to the processing of hyperspectral observations in the field of urban forests. Typical applications include mapping of surfaces covered with trees, transport network planning, studying urban heat islands, and measurement of vegetation stress, etc.…”

“…Hyperspectral images comprise a rich of data, but interpreting them needs a sympathetic of exactly what ground materials properties that can try to measure, and how relate to the measurements essentially made by the hyperspectral sensor. Imaging spectrometers are instruments which used for producing hyperspectral images [2]. The ratio of reflected energy to incident energy as a function of wavelength is called spectral reflectance.…”
