As the Edo State Branch of the Nigerian Institution of Surveyors (NIS) has decided to align with the agency (Edo Geographic Information Service) that is responsible for the processing of Certificate of Occupancy to be determining positions in the UTM system, the coordinates of the existing controls in the State have to be converted to UTM coordinates using conversion software. Consequently, this paper presents detailed procedures for the application of AllTrans and Columbus software for positions conversion between NTM and UTM systems in Minna datum. The Minna datum properties, as well as the NTM and UTM parameters, have been detailed for effective use. The step by step procedures to consider when applying the software have enumerated. It was recommended that the Edo State branch of the institution (NIS) should get the full and the latest version of the software. It was also recommended that there should be a lecture for the practical demonstration of the detailed procedures.
