    (U. P., 2006) Njoku, D. John; Okoli Chidi G; Atulegwu P. Uzoije; Iwuji, Martin C
    Corrected and uncorrected SPot XS Imagiries are used to achieved comparative assessment of build - up area land use and land use cover classes in Northwest Nigeria. The build -up environment showed on both imageries. The PAVM was used to determine the ability of data sets to produce similar results over the area . Result indicate a low PAVM value for the tertiary level urban land use and land cover classes except the commercial area. vacant lands, industrial area and open spaces show zero values. The results have implications on the planning of urban and natural resources development in the ecologically fragile region of Northwestern NIgeria.
