Fieldmark from Electronic Field Notebooks allows you to create notebooks for structured data collection in the field while your team is offline. Developed to support a wide range of field-based disciplines, Fieldmark forms can be customised for your project to streamline data collection in the field. Collect data where there is no mobile or network connectivity and seamlessly upload data when you return to base. Fieldmark supports teams of data collectors using the same notebook on a project. Forms can include photographs, GPS locations (including from attached Bluetooth devices), free text and structured input fields, relations between multiple entries and more. Forms are fully customisable via our online web portal. After your field data collection exercise, data can be exported from our servers for import into your analysis tools or data repository. Export as CSV/Zip files or use our API to build an integration with your toolset.
