Integration of Aeromagnetic and Landsat Data in the Analysis of Dump Site (Landfill) in Owerri, Imo State.

Magnetic study over South Eastern Nigeria was performed as part of a multi-technique geophysical investigation. Various magnetic data enhancement procedures such as, qualitative (second vertical derivative, total horizontal derivative, analytic signal, theta map, tilt derivative, total horizontal derivative of tilt derivative and horizontal tilt angle) and quantitative (Werner and Euler deconvolutions)  interpretation techniques were employed to determine their effectiveness in characterizing landfills. The study area has revealed that upward continuation, calculated vertical patient processing, and wavelength filtering significantly improved the interpretability of magnetic data in areas of discrimination between shallow and deep magnetic sources within the landfill. Furthermore, the vertical gradient calculated from surface observations is separable to gradients obtained from bilevel surveys, suggesting that the  efficiency of surveys can be increased by calculating, rather than observing the vertical gradient. Lineaments trending NE – SW and other adjoining lineaments are revealed by the second vertical derivative map. Similar indications are observed from the maps of first vertical derivative, theta, total horizontal derivative, tilt and horizontal tilt derivative.
