Geospatial Research Seminar Series (GRISS) – 5 March 2021
Global Satellite Navigations Systems such as GPS enable positioning information accurate to about 5-10 metres. A Satellite Based Augmentation System (SBAS) will improve the accuracy to less than a metre, and in some devices to 10 centimetres, and provide greater integrity. More precise and accurate positioning increases our productivity, secures our safety and enables innovation. Unlike most regions of the developed world where SBAS is available, Australasia does not currently have access to any reliable free-to-air augmentation services. LINZ and Geoscience Australia are working together to develop a regional SBAS to improve the accuracy of GPS.
Geospatial Research Seminar Series (GRISS) – 27 November 2020
Flooding is Aotearoa/New Zealand’s most frequent hazard and its impact will only increase under climate change through both more intense rainfall events and sea level rise. We are currently going through a massive flooding infrastructure revamp as well as investing in significant urban development. However, we don’t yet have a consistent national understanding of what our flood risk is now – let alone in the future.
