Jul 1, 2025

Summary for 2025-07 DEFRA/land-grants-api: Delivered major Parcels API enhancements and data-layer improvements with measurable business value. Key features include area calculation for parcels, switch of area fields to quantity in hectares with correct conversions, safe handling of null plannedActions, and integration of land cover data via PostgreSQL, plus merging agreement actions into parcel responses and related query optimizations. Data integrity and performance improvements for the land cover data and DB layer included data truncation during imports, new import scenarios, removal of dead code, and a new codes-action index; PostgreSQL pool reliability was improved to prevent token timeouts. Critical fixes addressed: ha-to-sqm rounding bug and null plannedActions, plus token timeout stability. Overall impact: more accurate parcel data, faster queries, more reliable data imports, enabling better land management decisions and reporting. Technologies demonstrated: PostgreSQL, SQL indexing, data import/ETL, API design and optimization, test coverage.
