Data & Metadata: The Backbone of Reliable BNG Assessments
In our ongoing exploration of the FRIDAS® checklist, today’s focus is on Data & Metadata—the elements that ensure biodiversity data is complete, transparent, and traceable.
Why Data & Metadata Matter
In Biodiversity Net Gain (BNG) planning, ensuring the accuracy and reliability of data is essential. The Data element focuses on supplementary datasets that support habitat classifications, while Metadata provides critical documentation to enhance the traceability of GIS datasets. Together, they ensure that data submissions meet rigorous standards, even when field surveys are impractical.
How Data & Metadata Support BNG
Supplementary Data:
When direct ecological surveys are not feasible, citing reliable datasets (e.g., Local Nature Reserves or Sites of Special Scientific Interest) strengthens the validity of habitat classifications. This approach allows for:
Greater data completeness, ensuring no critical information is overlooked.
Integration of external datasets for enhanced site analysis.
Metadata:
Metadata acts as a blueprint for your datasets, offering essential details such as:
Lineage: Tracks the origin and modifications of your data.
Extent: Defines the geographic area covered.
Keywords: Improves discoverability and usability. By adhering to standards like Gemini2.3, planners ensure comprehensive documentation, aligning with best practices for data governance.
Checklist Questions for Data & Metadata
Supplementary Data
Are there other relevant datasets included in your site data?
Was your site surveyed by an ecologist?
If no, what supplementary information supports your site classification?
Metadata Elements
Have you recorded key elements such as:
Title, Abstract, and Keywords?
Lineage, Extent, and Spatial Reference System?
Metadata Point of Contact and Resource Identifier?
A full list of mandatory metadata elements is available in standards like Gemini2.3.
Common Challenges to Avoid
Incomplete Documentation: Missing metadata can reduce trust and usability.
Unverified Data Sources: Relying on unsupported datasets weakens the credibility of classifications.
Inconsistent Standards: Failing to align with established metadata guidelines (e.g., Gemini2.3) can lead to non-compliance.
Practical Tips for Data & Metadata
1️⃣ Verify Sources: Ensure supplementary datasets are reputable and relevant.
2️⃣ Follow Standards: Use metadata guidelines like Gemini2.3 to document datasets.
3️⃣ Centralise Data: Maintain all supplementary data and metadata in a single, accessible location to prevent discrepancies.
FRIDAS® in Action
By addressing both Data and Metadata, this element of the FRIDAS® checklist ensures biodiversity data is accurate, well-documented, and traceable. These principles not only enhance BNG assessments but also build trust among stakeholders.
