The numerous defects of analogue cadastre, consisting of paper maps and land register, have forced the improvement and upgrading of the cadastre, which can be observed in many countries. The aim of this study is to apply GIS in the creation of digital cadastre for staff quarters in Covenant University Ota, Ogun State. Nigeria. The spatial data and some of the attribute data used in this research is mainly of primary source. The spatial data in this research refers to the coordinates of the control stations and observations of temporary beacons, roads, etc that were taken using South Differential GPS H66 base and rover (receiver). Attribute data on parcel information and ownership of each plot in the study area plan were obtained from the Department of Physical Planning of Covenant University-Ota, as well as through social survey and field verification. The secondary dataset consists of spatial UTM coordinates of two control stations for reference which were obtained from the Surveying and Geoinformatics department; College of Environmental sciences of Bells University of Technology, Ota- Ogun. To confirm the positions of the control stations, control check operation was done using a South Differential GPS H66 base and rover (receiver). The observational data was also acquired using the Differential GPS and then plotted on AutoCAD. The plotted data was exported to ArcGIS environment to produce the spatial database. This was linked with the attribute data to create the digital cadastre in ArcGIS software. GIS processing, manipulating, database query, analysis and displaying of the required information were performed. The results were presented as digital maps (thematic maps) and composite map showing the existing allocation patterns of plots/parcels in the estate. The database showed detailed characteristics of parcels, buildings and owners. It is recommended that the digital cadastre created in this research should serve as a model to create a database for all landed properties in Covenant University, Ota.
