1 Bathymetry User Needs and Challenges in Australia and New Zealand Nathan Quadros Shallow Water Survey February 212

2 Background Recent significant investment in Bathymetric LiDAR acquisition for climate change activities Research initiated to better understand the reasons for near-shore bathymetry collection and make sure that the appropriate strategies are being used to satisfy user needs. Funding: CRC for Spatial Information (CRCSI) Australian Department of Climate Change and Energy Efficiency (DCCEE) Support Intergovernmental Committee on Surveying and Mapping (ICSM) Australian Hydrographic Service (AHS)

3 Aims Identify the range of applications in which bathymetric data is being employed Understand the specific data requirements of these applications Summarise the features that make such data versatile, multi-use and fit-for-purpose Produce a report documenting the findings of the study Make recommendations for improving future data collection strategies
