Research interests

Nick Rollings is Geoscientist with over 25 years experience in mineral exploration, natural resource management, geospatial science, teaching and research.  He specialises in the application of GIS, remote sensing and associated geospatial technologies for natural resources assessment and management, mineral exploration and cultural data management.

His experience includes working in private industry, local government, consulting, and higher education. In the minerals sector, Nick has worked on exploration for gold, base metals, platinum group metals, industrial minerals, extractive minerals and uranium.  In the environmental sector Nick has experience applying geospatial technologies to forests, grasslands, soil erosion, water quality, benthic mapping, water quality, cultural information management, landscape futures, rehabilitation, hazard modeling and site selection.  

Nick’s current research concentrates on multi-scale UAV and satellite remote sensing for vegetation assessment and coastal assessment, and GIS modelling of cyclone track behavior and impact.  Nick has written several geospatial software applications including the development and implementation of large information systems. 

Nick is a Member of the Australian Institute of Geoscientists (MAIG).
