What is a best practice when open geospatial data include sensitive locations?

• A. Publish exact coordinates for full transparency.
• B. Limit data sharing to a single stakeholder with no governance.
• C. Release only aggregated statistics with no location data.
• D. Use privacy safeguards, aggregation, and consent where necessary.

Answer: (D)

Open geospatial data often contains layers with sensitive locations such as critical infrastructure, protected habitats, or vulnerable communities. The best practice is to guard privacy while preserving usefulness by applying privacy safeguards, aggregating data to higher-level units, and obtaining consent when needed. Privacy safeguards include methods like removing precise coordinates, blurring, or restricting access to sensitive layers. Aggregation groups points into larger areas so individuals or sites can't be identified. Consent ensures stakeholders agree to sharing particular data, respecting legal and ethical considerations. This combination maintains analytical value for risk management and sustainability while reducing the risk of harm. Publishing exact coordinates exposes sensitive sites and could enable harmful use. Restricting data to a single stakeholder with no governance concentrates control and undermines accountability. Releasing only aggregated statistics with no location data can preserve privacy but often strips away spatial detail needed for targeted risk assessment and planning. Therefore, the recommended approach is to use privacy safeguards, aggregation, and consent where necessary.
