Dr. Jonathan Stanger

Jon is an expert in interdisciplinary knowledge application. Beginning his career in academic research he synthesized knowledge from electrohydrodynamics, high precision instrumentation, materials science and data science to unravel fundamental properties of the electrospinning nanofabrication process. He followed this by giving back to the community by leading the STEM promotion initiative for Engineering in Victoria for two years before returning to academia to lecture on Mobile Communications Networking. His next leap was to work with partners of NBN to help solve the challenging problem of designing a cost effective network by reusing existing infrastructure. Finally he has recently landed in the data science space, delivering solutions relating to predictive asset maintenance and unsupervised data segmentation. Each step in his career he has been able to draw knowledge and expertise from prior disciplines and apply them in relevant ways. This has allowed him to find creative and novel solutions to existing and sometimes intractable problems.

Jeremy Palmer

Jeremy is the Director Data at Toitū Te Whenua Land Information New Zealand and has been using FOSS4G since 2003! His journey into using open source geospatial began in 2003 when I was working on a data management project for his agency. He was struggling with finding a suitable solution for managing large geospatial dataset until he discovered PostGIS, an open source geospatial database. He was so surprised by the dedication of the developers who worked tirelessly to help him solve his problems, even if the software didn't originally support his need. This discovery opened up a whole new world of possibilities for him, as he realised the potential of open source and open data to transform geospatial analysis and make it more accessible to everyone. As he continued to explore the open source geospatial community, he found himself drawn to the collaborative and innovative spirit of the community. The open source geospatial community was passionate about using technology to solve real-world problems, and he knew that he wanted to be a part of that movement. He is the recipient of various personal and team awards including: Personal Achievement - Winner of the ‘New Professional of the Year’ award at the 2013 Institute of Public Administration New Zealand (IPANZ) Public Sector Excellence Awards; LINZ Data Service - Winner of the ‘Spatial Enablement’ category and the JK Barrie Award for Overall Excellence at the Asia-Pacific Spatial Excellence Awards (APSEA) 2012 (Manager of the LINZ Data Service); and LINZ Data Service - Winner of the Geospatial Application Excellence Award in Infrastructure, Geospatial World Awards in Geneva 2014 (Manager of the LINZ Data Service)
