Abstract
Using second generation of biofuel that does not affect food crop production is an issue
of global concern. Remote sensing (RS) proved to be efficient technique for inventory
and monitoring the spatial distribution of biofuel plants at both local and regional
scales. It is used also for site selection of the most suitable sites for the plantation of
these plants through the integration of multi spatial layers. Spectral identification of
these plants and the relationship between spectral and morphological parameters were
not observed.
This work is considered the first step of a series of studies deals with the identification
of the spectroscopic parameters and their relation with morphological parameters of
the most common Egyptian natural vegetation. At this stage, two sources of fossil oil
plants Jatropha and Jojoba were investigated. Spectral reflectance was measured using
ASD spectroradiometer device and the spectral signature was identified for the two
taxa. Secondly, optimal spectral zone and wavelength/s were identified for each
sample. A Strong relation was found between chlorophyll content and spectral
reflectance at visible spectral region. Normalized difference vegetation index (NDVI)
was found to be highly correlated with chlorophyll content. Further work will be
carried out to quantitatively relate the amount of ingredient fossil oil of these plants
with spectroscopic characteristics.
