Global Navigation Satellite Systems & Elevation Data

Date: 1 July 2009

In June 2008, NZGO organised a day of presentations around the topics of Global Navigation Satellite Systems (GNSS) and elevation data, including light detection and ranging (LiDAR). A focus of the day was the importance of geospatial information to local councils' planning and services infrastructure.
