Comparison of machine learning and statistical approaches for digital elevation model (DEM) correction: interim results
Chukwuma Okolie, Adedayo Adeleke, Julian Smit +3
Several methods have been proposed for correcting the elevation bias in digital elevation models (DEMs) for example, linear regression. Nowadays, supervised machine learning enable…
Digital elevation model correction in urban areas using extreme gradient boosting, land cover and terrain parameters
Chukwuma Okolie, Jon Mills, Adedayo Adeleke +1
The accuracy of digital elevation models (DEMs) in urban areas is influenced by numerous factors including land cover and terrain irregularities. Moreover, building artifacts in gl…
Quality Assessment of the 20m SPOT DEM in Nigeria
Peter Nwilo, Johanson Onyegbula, Chukwuma Okolie +3
The 20m SPOT DEM (Digital Elevation Model) was acquired by the Office of the Surveyor-General of the Federation (OSGoF) in Nigeria for use in topographic mapping. A localized asses…
Computing Traffic Accident High-Risk Locations Using Graph Analytics
Iyke Maduako, Elijah Ebinne, Victus Uzodinma +2
Analysis of the dynamic relationship between traffic accident events and road network topology based on connectivity and graph analytics offers a new approach to identifying, ranki…
Positional Accuracy Assessment of Historical Google Earth Imagery
Peter C. Nwilo., Chukwuma J. Okolie, Johanson C. Onyegbula +6
Google Earth is the most popular virtual globe in use today. Given its popularity and usefulness, most users do not pay close attention to the positional accuracy of the imagery, a…
A systematic review and meta-analysis of Digital Elevation Model (DEM) fusion: pre-processing, methods and applications
Chukwuma Okolie, Julian Smit
The remote sensing community has identified data fusion as one of the key challenging topics of the 21st century. The subject of image fusion in two-dimensional (2D) space has been…
