Topographic Map Update of Esan Central LGA, Edo State, Nigeria, Using SPOT-5 and ASTER LiDAR Data

S. O. Ogedegbe^*

This study examines the effectiveness and accuracy of SPOT-5 and ASTER LiDAR data satellite images, Global Positioning System (GPS), Digital Terrain Model (DTM), and Geographic Information System (GIS) in carrying out a revision of Nigerian topographic maps at the scale of 1:50,000. The data for the study were collected by extraction of relevant spatial data from the 1964 topographic map, delineat...

Decadal Intensity Analysis and Landscape Fragmentation of Land Use land Cover Change in the Owesse River Basin, Southwest Nigeria

Babatola O. Orisaniyi^*, J. S. Ojo, Ayobami Aluko, D. D Hamza, Glory Enaruvbe

Land use and land cover (LULC) change and landscape fragmentation pose significant threats to ecosystem sustainability in tropical river basins, particularly in rapidly developing regions of sub-Saharan Africa. This study assessed the spatio-temporal dynamics, intensity, and fragmentation of LULC change in the Owesse River Basin, Southwest Nigeria, over a 30-year period (1994–2024). Multi-temporal...

Comparative Assessment of Nigeriasat-X and Landsat ETM+ Satellite Data in Groundwater Potential Modelling using a part of FCT as Case Study

Olatunji Sunday ABOYEJI^*, Oluwaseyi Emmanuel OLUWAFEMI

Groundwater is an important natural resource that supports plants and animal lives. An important factor responsible for its scarcity in developing countries is increasing urbanisation resulting from rapid growth in population and the associated anthropogenic activities. Many studies have used Landsat data for groundwater potential modelling. Information on the usability of NigeriaSat-X data for th...

GNSS Sky Visibility Planning and Dilution of Precision Analysis for EOS Ground Station Selection for Nigeria Space Programme

M. L. Ojigi^*, J. D. Dodo, Y. D. Opaluwa

The establishment of Earth Observation Satellite (EOS) ground receiving stations in parts of Nigeria and other parts of the globe, similar to the Indian Remote Sensing (IRS) model will enhance global telecommand, precise EOS tracking, data transmission, and distribution of NigeriaSat data, which will enhance global-scale data awareness, usage and higher financial returns for Nigeria. This study, t...

Modelling Changes in Land Use Land Cover in the Sudan Savannah Ecological Zone of Northwestern Nigeria

Armiyau Shehu MACCIDO^*, Olatunji Sunday ABOYEJI, Lukuman MUHAMMAD, Ahmad Rufa’i AHMAD, Yusuf Diwa PATRICK, Matthew Olumide ADEPOJU, Godstime JAMES, Monsur Olaide ADEROJU, Halima ALIYU, Dalhatu AHMAD

Climate change is one of the most global environmental concerns in the 21st century. This study modelled the historical changes and future projections of Land Use Land Cover (LULC) in the Sudan Savanna ecological zone of Northwestern Nigeria. The research analyzed multi-temporal Landsat imagery (2004, 2014, and 2024) to quantify past trends and projected future scenarios for 2035, 2045, and 2055. ...

Geospatial Assessment of Urban Heat Island and Climate Dynamics in Ile Ife, Southwest Nigeria

A. M. Adesiyan^*, S. O. Akande, Joseph Oloukoi

Rapid urban growth can alter surface energy balance and intensify surface urban heat islands (SUHIs), yet secondary cities in sub-Saharan Africa remain comparatively understudied. This study assessed spatiotemporal surface thermal dynamics and local climate variability in Ile-Ife, Nigeria, using Landsat scenes acquired on 15 January 1986, 3 January 2002 and 25 December 2024, MODIS MOD11A2 land sur...

Geospatial Analysis of Coastal Flooding Effect on Soil and Vegetation in Ilaje Local Government Area of Ondo State, Nigeria

Efosa G. Adagbasa^*, Olusola O. Ige-Olumide

Soil salinity is believed to be mainly responsible for low land use as well as agricultural productivity in coastal regions of the world. The entire coastal area of Ondo State is affected by coastal flooding which causes saltwater to inundate the top and impregnates them with soluble salts, thereby rendering the soils and subsoils water saline. This study applied a Geo-information technique not on...

Spatial Pattern of Cholera Incidence in Ibadan City

E. A. Salubi^*

The recurrence of the cholera outbreak in Ibadan is alarming and very little has been documented on its spatial pattern. Hence, this study investigated the spatial pattern of cholera in Ibadan using GIS techniques and spatial statistics. Cholera is a disease that has been known to be associated with poor environmental sanitation. However, the impact of other contributory factors is also becoming e...

Geographic Information Science as a Paradigm Shift

Bola Ayeni^*

This paper demonstrates that the advent of GIS has led to situations in the processes of scientific investigation that are indicative of a paradigm shift in both research focus and efforts in the environmental and social sciences, delivery of health facilities and services, and in numerous areas of urban and regional planning. It is argued that the deep involvement of Geographic Information Scienc...

Coastal Land Subsidence and Morphological Changes within Nigerian Coastal Areas

Oluseyi O. Fabiyi^*, Glory Enaruvbe

Nigerian coastline is increasingly subjected to a number of geomorphic, structural, and morphological changes due to a combination of several processes and change factors. Land subsidence is one of the major events causing geomorphic and morphological changes in the coastal areas. This study utilized GIS techniques, multi-date remote sensing data, auxiliary data, and fieldwork to examine, identify...
