SPECTRAL SIGNATURES OF SOILS AND OTHER COMMON COVER TYPES IN ANTEQUERA, SOUTHERN SPAIN
M.A.Nwachokor, Olaniran E. Aluko
This study was carried out to determine the spectral signature of the soils and other most common cover types under field conditions in Antequera, Southern Spain. Subsequently, the potential of this information as reference data for enhancing the utility of Remote Sensing Technology to achieve sustainable development of the predominantly agricultural area was evaluated. A spectroradiometer (Exotech ERTS radiometer model 100) was used to measure the spectral reflectances of the different terrestrial target objects in accordance with standard procedure. The instrument had four bands which corresponded to the four bands of Landsat MSS in the wavelength range of 0.5 – 1.1μm. Results revealed that the cover types exhibited a distinctive spectral response pattern or spectral signature so that they could be distinguished from one another. Also, the measured reflectances correlated with those of Landsat MSS data, thus suggesting that the data could be used to calibrate airborne and satellite sensors. Clearly, therefore, the data presented a high potential to enhance the usefulness of remote sensing for inventorying, monitoring and management of the land resources to achieve a sustainable development of the sub-region.
