ASPIS, A Flexible Multispectral System for Airborne Remote Sensing Environmental Applications

View Article: PubMed Central

ABSTRACT

Airborne multispectral and hyperspectral remote sensing is a powerful tool for environmental monitoring applications. In this paper we describe a new system (ASPIS) composed by a 4-CCD spectral sensor, a thermal IR camera and a laser altimeter that is mounted on a flexible Sky-Arrow airplane. A test application of the multispectral sensor to estimate durum wheat quality is also presented.

No MeSH data available.

f8-sensors-08-03240: Example of ASPIS calibration filed false colours composition image. The white square indicates the part of the images used in the index calculation to reduce the bidirectional reflectance effect.

Mentions: The REMS index was calculated for each of the 12 sub-plots on the basis of a total of 10 images. To limit the bidirectional reflectance effect to the index calculation, only the central part of each image was used to calculate REMS, with a FOV of about 8 degree around the nadir axis (figure 8). In each of the 10 images there were always 2 or more sub-plots falling in the sub-area considered (white square in figure 8). For each sub-plot, all the pixels available (commonly between 700 and 12000 in each frame) in the whole set of images have been used to calculate the mean REMS index value.
