Geodata Curation
Definition
Geodata curation involves the meticulous process of managing, preserving, and stewarding geospatial data. This process ensures that geospatial data remains accessible, accurate, and usable over time. Geodata curation encompasses a wide range of activities including data collection, validation, archiving, maintenance, and quality assurance. Effective curating practices are vital for enabling long-term data usability, supporting reproducibility in research, and facilitating informed decision-making using geospatial data.
What is Geodata Curation?
Geodata curation is a comprehensive approach aimed at the systematic management of geospatial datasets. It refers to the practices and methodologies employed to handle geospatial information throughout its lifecycle—from initial data creation and acquisition to its distribution and eventual archiving. This involves setting metadata standards, ensuring data integrity and security, implementing data version control, and establishing protocols for data dissemination and sharing. Geodata curation is critical in promoting data discoverability, enabling interoperability among systems, and supporting the veracity of analytical and research undertakings that rely on spatial data.
