Mobilizing biodiversity data requires addressing significant information gaps. Improving georeferencing in biodiversity datasets is crucial for enhancing data usability for science and policy.
Area of Science:
- Biodiversity Informatics
- Data Science
- Ecology
Background:
- The field of biodiversity informatics is expanding, but a large portion of existing biodiversity data remains inaccessible.
- Mobilizing this data efficiently is critical for scientific research and policy-making.
Purpose of the Study:
- To analyze large-scale biodiversity datasets to identify information gaps and data attrition.
- To determine the most effective strategies for improving data usability.
Main Methods:
- Analysis of large-scale biodiversity datasets focusing on birds and plants.
- Detection of information gaps and data leakage across taxon, time, and place dimensions.
- Assessment of the impact of data completeness on usability.
Main Results:
- Significant data leakage was observed across all dimensions (taxon, time, place) in the analyzed datasets.
- Geographic referencing (place information) was consistently the least complete data dimension.
- Incomplete georeferencing significantly degrades the usability of biodiversity information resources.
Conclusions:
- While digital capture and quality control are important, addressing georeferencing is paramount for immediate gains in data usability.
- Prioritizing georeferencing efforts will maximize the mobilization of existing biodiversity data for science and policy.
