GeoNet is currently migrating its data from the legacy FITS database to the modern Tilde common time series API. This change is part of our effort to phase out the outdated FITS system and move to a more up-to-date, flexible, and reliable data infrastructure.
The Tilde Common Time Series API has a website with API documentation, graphing tools for data exploration and API URL endpoint creation features. You will be able to use this new access mechanism to update your code so that it can still access the same data.
Data Discovery tool for plotting and viewing time series graphs, API request creation and downloading the time series data in JSON and CSV format.
Data Exploration tool for plotting and comparing multiple data sets and bookmarking visualisations.
The FITS database, while foundational in the past, no longer meets the growing demands of modern data handling and analysis. The Tilde API brings improved data access, more robust features, and greater compatibility with emerging technologies. By switching to the Tilde common time series API, you’ll benefit from enhanced performance and future-proofed functionality.
We are migrating four major datasets as part of this transition:
Volcano monitoring manually collected data
GNSS daily position solutions
ScanDOAS, including data from Whakaari/White Island formerly referred to as mini-DOAS
Inferno Crater Lake Data, historic data collected by a legacy datalogger system before the current envirosensor system began operation
Each dataset will be accessible through the Tilde API, offering the same essential data in an updated format. To support your transition, we provide detailed documentation and data exploration features designed to help you understand the Tilde API in depth and modify your code to align with its new structure.
Our migration process involves a staged deactivation of datasets in the FITS system. Each dataset will be turned off on different dates, allowing you time to adapt your code to the Tilde API individually.
You can keep track of the current migration status and upcoming deactivation dates in our status table below:
| Data Set | Available in FITS | Available in Tilde | Target Date of Deprecation in FITS |
|---|---|---|---|
| Volcano Monitoring manually collected | Yes, but no new data since March 2024 | Yes, fully up to date | December 1st 2024 |
| ScanDOAS | Yes, Ruapehu, Tongariro and Whakaari/White Island | Yes, Ruapehu and Tongariro only | December 20th 2024 |
| GNSS daily position solutions | Yes | No | March 1st 2025 |
| Inferno Crater Lake historic datalogger data | Yes | No | February 1st 2025 |
Please check the status table regularly to understand when each dataset will be deactivated on FITS and make sure your code is updated accordingly.
Our team is here to help you through this migration. For each dataset, we've created a Transition Guide with detailed steps and example code to make the transition as smooth as possible. We will update this guide as datasets are migrated. Additionally, our support team is available to answer questions and assist you with any challenges you may encounter.
