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.
