Abstract:

The significance of Cadastral Surveys in facilitating effective land titling cannot be understated. In Niger State, land titling procedures have long been a concern for geo-spatial experts. This study focuses on revalidating 20 selected Title Deed Plans (TDPs) to identify potential positional, dimensional, orientational, and locational errors within them. The revalidation survey was conducted using the V30 Pro GNSS DGPS receiver unit, and the results were compared with existing TDPs.

Out of the twenty resurveyed land titles, fifteen did not meet the required accuracy for Third Order cadastral surveys as stipulated in the cadastral law. The orientation deviation between the existing and resurveyed TDPs ranged from 04032’28’’ to 10015’56’’, while the differences in distances ranged from 0.86 to 1.64, respectively. Based on these findings, recommendations were made to improve observational and procedural standards.

Furthermore, a web-based application was developed to address these concerns. This application used Google Earth Imagery as the base map and incorporated the seven-parameter transformation model developed by OSGOF (2018) to ensure datum/positional consistency between the existing cadastral system and Google Earth. This transformation automatically converted all coordinates from Clarke 1880 to WGS84. The web-based application was developed using HTML, CSS, JavaScript, and PHP, and it has the potential to aid in land verification and enhance the accuracy of land measurements for effective cadastral practices in Niger State.

As a result of this study, it is strongly recommended that revalidation surveys be conducted for all existing titles in the State to ensure accuracy and reliability in the land titling process.
