Nigeria yet to exploit RS tech in mineral exploration

Abuja, Nigeria: Nigeria should use remote sensing (RS) in mineral exploration. So far, the RS data has been used in hydro geological applications in the country, observed Dr. Lazarus Ojigi, Associate Professor of Geomatics at the Space Application department of National Space Research and Development Agency (NASRDA). He was speaking at the National Space Dialogue in Abuja.
Recalling early days, Ojigi stated that aerial photographs were used to evaluate topography and plan mineral prospecting and sampling surveys in Enugu, Okaba and Jos. He added that aerial photographs of a particular mining site were compared with the photographs of other sites to determine the possibility of similar type of minerals. However, it was not very effective.
Ojigi explained that remote sensing technology can be very effective because it can identify minerals and rocks through spectral features. Today, airborne hyperspectral imaging (HSI) sensors provide high-spatial resolution (2-20m), high-spectral resolution (10-20nm) and high Signal-to-Noise Ratio (SNR) (>500:1) data for a variety of scientific disciplines.
