OUTSTANDING ACHIEVEMENTS Some outstanding achievements during the period under review are as follows: Establishment and maintenance of more Continuously Operating Reference Stations (CORS) in various parts of the country; Deployment of Zero order Controls which enables the mapping sector to tie Survey controls to other Nations through International terrestrial Reference Frame (ITRF); Acquisition of 2.5m resolution satellite imagery and 20m Digital Elevation Model (DEM) for the entire country. This has enabled the Office to produce 1:25,000 maps faster and more accurately;
OUTSTANDING ACHIEVEMENTS CONTD Determination of transformation parameters from Nigerian Minna Datum to the Global using Nigerian experts; Establishment of a Data Centre in the Office where all survey and mapping data/information are stored and made accessible to all stakeholders; Publication of Second Edition National Atlas of the Federal Republic of Nigeria. The first edition was published over thirty (30) years ago; Updating of the Abuja Street Guide Booklet and Digital Street guide map of more than thirty (30) states has been completed.
FUTURE PLAN It is part of the Office future plan to: Continue with 1:10,000, 1:25,000, 1:50,000 and 1:100,000 map coverage of the entire country; Establish more COR Stations; Establish a Survey Museum; Produce school Atlas; Intensify efforts in resolving boundary issues; Complete the Data Centre and establish Remote Data Centre as Back-ups; Sensitise the State Governments to map for development etc.
