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.
