OSi also licences data for a wide range of computer based applications such as Computer Aided Design (CAD) and Geographic Information Systems (GIS).

OSi products are state of the art, produced using the most up to date technology to international standards and, consequently, the company is a leader in the Irish geographic information market.

OSi owns a network of 25 GNSS (Global Navigation Satellite Systems) stations around Ireland, continuously recording and streaming data from satellites back to the agency’s centre in the Phoenix Park in Dublin. That information is then processed

in real time. In all, OSi stores a total of some 640 terabytes in 30 separate databases. OSi has significant experience in data management and database management.

All products are available directly from the OSi shop (+353 1 802 5300) at the OSi headquarters in the Phoenix Park (near Castleknock Gate) through its online shop and through a national network of retail outlets.
