The School of Surveying & Spatial Information Systems is one of the schools of the UNSW Faculty of Engineering - the largest engineering faculty in Australia. The School offers two B.Eng. degrees, one in Surveying and the other in Geoinformation Systems. From the very beginning the School has placed a great emphasis on Research, initially in the fields of Geodesy, Photogrammetry, Survey Adjustments and Remote Sensing.

Since the mid 1980s the focus has changed to high accuracy GPS technology and applications, and since then has expanded to Global Navigation Satellite Systems (GNSS) and wireless positioning systems in general. In addition new research strengths have developed in radar remote sensing, Lidar, signal processing and GNSS receiver design. The current research areas can now be placed under the general umbrella of "Navigation and Earth Observation".
