This paper focuses on Geographic information system (GIS) as a tool for effective management of an estate and its resources such as road, parcel building, electric poles, land use, ownership and address. The methodology includes capturing of the geometric and attribute data for parcels, buildings and other amenities such as electric poles, well, drainage system using land surveying method, creation of database (spatial/attribute) for the features in the area under study, and performing spatial analyses on the databases presentation. The geometric data acquisition was carried out using GPS and Total Station while oral interview was used for attribute data acquisition. The processed data was drafted with AutoCAD 2017 software while the database was designed using ArcGIS 10.3. Database (Extraction) queries were generated in ArcGIS 10.3 and the result of these queries is a useful tool towards decision making. These queries are useful tools for the management of the estate by the state government towards effective tax collection and provision of basic amenities. Based on the findings of this research, the following recommendations were made: Government should encourage the use of GIS, so as to create more awareness on the use of GIS as a tool for decision making, GIS is recommended in producing composite map that will show the parcels, buildings, boundary, roads, drainages, wells and electric poles, and finally, GIS is recommended to the authorities that are saddled with the responsibility of the management of an estate.
