Geospatial Surface Area Mapping of Bokkos Local Government Area (LGA) of Plateau State of Nigeria
The study is a geospatial surface area mapping of Bokkos LGA physical features through the aid of geographic information system (GIS) application that was used to analyze surface conditions plotted from reported data which dwell the contour, slope, aspect, curvature and hill shade maps as well as a land-use map. The morphometric parameters were derived from the Digital Elevation Model (DEM) using ArcGIS. The result revealed 433 contours with 100m intervals with less around Kwatas, Bokkos, and Butura and very high around Mushere west and central. The slope was very high around Mushere west/ central, Mangar/Damwai, Dafffo, Sha and Mangunahave moderate slope. In areas of Mushere, Mangar and Damwai runoff was high, soil erosion indicated sign of very high adverse effects on the environment. Aspect revealed red colour, North, orange Northeast and yellow colour tilt to the east while the green southeast. Hillshade was observed lesser in Mushere west/central, Damwai with a curvature map for soil erosion patterns and Vegetation covers were predominant certain areas of Bokkos and the study gave appropriate recommendation to agency concerned
