Description: GNS Science Te Pū Ao, through its GeoNet programme, operates a multidisciplinary sensor network to monitor geological hazards in Aotearoa New Zealand. Data from more than 800 permanent monitoring sites are continuously collected, transformed and delivered to a range of end users.Managing multidisciplinary instrument metadata is a key task of the GeoNet datacentre. In 2017 GeoNet moved away from using a corporate relational database to using a modern and novel approach to manage metadata. All of this metadata is freely available and treated as a dataset (DOI: 10.21420/0VY2-C144) to give users access to whatever metadata they need and to improve visibility and usability.This system is at the core of the GeoNet data pipeline and allows the data transformation process, from the field to end users, to be automated. The system uses a software development approach: a code versioning system based on git and hosted at “github.com/GeoNet/delta” which allows instrument metadata and their changes in time to be peer reviewed, version controlled and checked for consistency. Equipment and installation details are stored as a set of CSV files and short XML seismic response file segments. This allows for easy access and maintenance, with no proprietary external software needed to decode or examine the information.

Description: Aotearoa New Zealand's GeoNet programme was launched with an open data framework to support research, monitoring, and geohazard response at its core. Open data has proven to be hugely successful for GeoNet funders and user community and continues to be at the heart of GeoNet. GeoNet is now evolving to develop new services, storage, processing, and dissemination mechanisms to meet emerging data usage requirements (for example: requests to access large data volumes). Over the last few years, GeoNet has taken some major steps forward in supporting data access, usability, and resilience in data operations: GeoNet moved its diverse data collection, processing and storage to the cloud (Amazon – Web Services). This includes the development of a data lake strategy; GeoNet released TILDE, a system to disseminate low to medium sample rate datasets in a common format, that supports access via an Application Programming and a Graphical User Interfaces; GeoNet partnered with AWS Open Data Sponsorship Programme to make a copy of its data freely available for large data query access. GeoNet continues to face other challenges: understanding and tracking impact and data use (user registration and authentication for data access?), quality monitoring, adoption and impact of new initiatives (e.g. citizen science), improving integration of Te Ao Māori, and significant expansion of data volumes and variety. But with challenges come opportunities and GeoNet looks forward to working with the broader international community and fostering discussions to how best to balance data funders/providers/users needs whilst keeping open data as a core principle.

Description: Aotearoa-New Zealand islands sit in the South-West Pacific region where tectonic activity generates one of the world largest seismicity, intense deformation, and volcanic activity. Since 2001, GNS Science Te Pū Ao ensures some of the New-Zealand capability to identify, study, prepare and respond to multiple and frequent geological hazard with the GeoNet programme. GeoNet builds and operates a permanent seismological network routinely maintained and upgraded to provide continuous observations for national and regional events, strong motion and building monitoring. Sensors are distributed over the country with regards to population and hazards exposures. GeoNet strives to optimize its network capability and improve its multi-purposes nature. Around 500 near-real time seismic sensors are acquired, archived, and processed into different products over timelines that match a variety of users and requirements. A range of both rapid and curated products are made available for public awareness, scientists and for earthquakes, landslides, tsunami, and volcanic panels and duty officers. We present the current New-Zealand seismological network, flow process and observation settings as it is, today, a mature observation system. We describe a range of derived seismic products and services designed to enable rapid, dynamic, robust, and resilient scientific seismic information to diverse communities with an open data approach from field instrumentation to data archiving. We discuss expectations and incoming challenges to handle technical and scientific transformations with a care for continuous integration process and maintenance required to evolving monitoring, response, and seismology scopes along with modern 24/7 operations center infrastructure strict design and functions.

Description: Aotearoa-New Zealand islands present some of the world largest seismicity, intense deformation, and volcanic activity. In this environment, GNS Science - Te Pū Ao implements the GeoNet programme since 2001 to satisfy needs and requirements for identification, study, preparedness, and mitigation of frequent geological hazards. With a wide range of air pressure, coastal and deep-sea level sensors, cameras as well as numerous GNSS, seismometers and accelerometers, GeoNet teams not only manage, collect, process, and archive hundreds of instruments but also implement a diversity of services and publicly distribute and maintain open data products. The GeoNet programme aims at enhancing New-Zealand hazard information by continuously developing, integrating, and upgrading its sensor networks and related tools: Instrumentation Database, field instrumentation QC applications, seismic network capability assessment tools, automated updating services etc…The resulting processed information is distributed through high performance and resilient web-services, alerting applications, data streams (real time and archives). In addition, near real-time and curated data products such as strong motion parameters, slow slip observations or eruption detection systems are provided to scientists and public, infrastructure, emergency management and governmental agencies. We present a summarizing assortment of GeoNet data, services and products sourced from more than 20 years of programme implementation. We describe challenges to maintain the current systems, ensure the resiliency, operational status and enable evolving observation methods, products, and services, to integrate new instrumentation types along with strict requirements for 24/7 national geohazard monitoring and for operational science during routine and significant event response.
