The Hyperspectral Sensors Used in Satellite and Aerial Remote Sensing

This article presents a number of issues that are related to the hyperspectral sensors which are part of new technologies for the acquisition of images in satellite and aerial remote sensing. Hyperspectral sensors are characterized by the fact that they produce records in a large number of adjacent and narrow lanes thereby providing a very high spectral resolution. In this way, interpretations and analyses can be made of the remote images at the micro-level, highlighting the features of details which could not be underlined with multispectral sensors. There are many applications that use hyperspectral images and they are related to agriculture, forestry, geology, environmental monitoring.
