The Federal Ministry of Works, in collaboration with the Office of the Surveyor General of the Federation, has opened a new vista transformation parameter in works sector.
Minister of Works, Mike Onolememen, who declared a workshop opened in Abuja, stated that the occasion afforded the Federal Government the chance to appreciate surveying and mapping products which are produced on a referenced datum, either topocentrically or geocentrically.
He added that the goal of President Jonathan’s transformation agenda is to make Nigeria one of the top twenty economies in the world by the year 2020, thus imploring the participants to be mindful of this and come up with an acceptable set of transformation parameters to guide the profession in the country.
Onolememen stated that he was aware that a lot of surveying and mapping activities around the country were being carried out on various local origin, which is neither Minna datum (Clark 1880) nor World Geodetic System 84 datum.
The Minister expected that the overall outcome would be the harmonization of old and new maps in one seamless whole, facilitating the desired physical development and the transformation of the country. He believed that the workshop will also translate into production of more accurate and current maps, maps substitutes and other geo-information products, adding that the WGS 84 which is a world geocentric referenced datum and which is a global best fit datum would be more desirable for Nigeria.
The Minister of State for Works, Amb. Bashir Yuguda, who also graced the occasion, said the focus of the workshop connoted academic exercise which will adopt a suitable set of transformation parameters that will not only provide opportunity to merge maps and other geo-information products produced on different platforms but will also translate into production of accurate maps and other Geo-information for the nation’s national development.
Yuguda, who believed that maps are a sine qua non to physical development, noted that it will assist in the provision of functional and sustainable infrastructure, affordable housing, land management, population census and delimitation of electoral wards and national planning would remain impossible without accurate, current and seamless maps.
Earlier, in his remarks, the Surveyor General of the Federation, Professor Peter C. Nwilo, stated that the relationship between Global and Local Datum is normally established by transformation parameters which are a set of values that enable one to convert from one datum to another and vice versa.
He added that these sets of values are expressed in three translation parameters, three rotation parameters and a scale.
