Fieldmark™ is an open-source tool for creating custom mobile applications for offline field data collection. It was launched in 2023 by the FAIMS Project in partnership with the Australian Research Data Commons (ARDC), Macquarie University, CSIRO and other partners.

How does it work?

Fieldmark™ runs on a web browser, Android, and iOS. Notebooks can be customised to collect structured, geospatial, instrument and multimedia data to suit any workflow. They can be shared from an online or offline server to registered users.

Who can use it?

Fieldmark™ was built for researchers who want to collect and share high-quality, FAIR-compliant data. It can be used by individuals, teams and large organisations.

Collecting data

Fieldmark™ has inbuilt formats for free text, GIS data (points, lines and polygons), dropdowns and picklists for controlled vocabularies (including hierarchical and picture selectors) and image and file attachments. Record metadata allowing for certainty and annotations are designed to suit the needs of researchers.


Records are stored on the local device and synchronised with an offline or online service at the first opportunity. Users can choose whether or not to synchronise large files and attachments.

Exporting data

Data can be exported from Fieldmark into .csv, .kml, .json and other formats, as needed. Images, files and folders are renamed in accordance with the record’s chosen identifier, saving time when you return from the field.
