The integration of computer technology and software in various aspects of land surveying provides surveyors with tools to enhance efficiency, accuracy, and productivity in their workflow. Land surveyors routinely engage in the complex process of managing land layouts, especially when traditional, non-digital methods are employed. This paper aims to streamlining the workflow for developing a legacy land layout using Computer-Aided Surveying (CAS) technologies. It demonstrates how CAS can be utilized for Site Selection, Layout Perimeter Plotting, Georeferencing, Parcel Digitization, Integration with GIS Database, Plot Area Calculation, Survey Data Extraction, and Topographic Map Generation. To realize this aim, the study utilized an old survey layout plan of Gunki that was manually produced in the 90s that covers an area of 185793.57m2 (18.58 Ha). AutoCAD, QGIS and Surfer were the software used in preparing the survey data while ProMark™ 800 Differential Global Positioning System (DGPS) was used in staking out the layout plan. A total of one hundred and eighty-five (185) plots of land covering an area of 195260.26m2 (19.53Ha) were identified and processed. 95% were identified as residential parcels/plots while the remaining 5% makes up of commercial, industrial and recreational plots. This paper establishes the effectiveness of CAS technology in modernizing and implementing a legacy layout plan for land development in Nasarawa LGA. The methodology outlined can be replicated across various regions facing similar challenges with outdated land-use plans.
