Abstract [en]

This study investigates the proposed extension of the existing runway of Margaret Ekpo International Airport, Calabar, Cross River State, Nigeria. The process involves the application of Geographic Information System (GIS) and several geospatial techniques for analysis and result presentation.

The aim of the study was achieved with the following resources: satellite imagery downloaded from the Landsat webpage and processed to generate a land use map of the study area; a Digital Elevation Model (DEM) covering the study area which was downloaded from the Consortium for Spatial Information’s (CSI) webpage and observed ground spot heights along the straight path of the proposed runway extension covering a total length of 2.5km and 200m wide. These datasets were modified, processed and assigned the same coordinate system in order to make them conformal for analysis. A GIS was created with the foregoing resources in conjunction with other geospatial applications such as ERDAS Imagine and Surfer 8 to carry out the analysis.

The analysis covered the environmental impacts of the proposed project, its effects on already existing human settlements and the huge cost implications based on certain conditions like the mandatory straight path which has to be maintained as an extension of the existing runway. Other factors considered are; the land use of the extension area, the economic benefits of the project, the accessibility of the area, noise pollution as well as the safety and security issues involved.

A summary of the result of our analysis shows features such as residential settlements, roads, swampy areas, valleys and areas of high elevation which will act as obstructions along the proposed  runway path. Also, the total surface area of the proposed runway and the volume of earth material required were calculated. The results achieved from this study shows that GIS and other geospatial tools are indispensable resources in complex planning processes such as facility maintenance and management.
