Survey Data QA/QC & Spatial Standards
Quality assurance and standards compliance for surveyed spatial data. ISO 19100, ICSM, and ANZLIC-aligned data validation, coordinate system management, and metadata standards.
Survey Data & QA/QC
Spatial data quality is not optional in government, utility, and infrastructure environments — it is a legal and operational requirement. Airfree Geospatial provides specialist survey data validation, QA/QC workflow design, and spatial standards compliance services. We work with survey datasets at all scales, from cadastral boundary data to large-scale infrastructure corridor surveys, ensuring that data delivered into enterprise spatial systems meets defined accuracy, completeness, and standards requirements.
Data Quality Risk
Survey data entering enterprise GIS environments without rigorous QA/QC carries significant operational and legal risk. Coordinate system errors, topology violations, attribute inconsistencies, and metadata gaps can propagate silently through data management systems — compromising decisions made years after the original survey. Systematic validation workflows prevent these failures at source.
What We Deliver
Survey Data Validation
Automated and manual validation of survey datasets against defined accuracy standards. Coordinate comparison, topology checking, attribute completeness audit, and outlier detection using QGIS and Python scripting.
ISO 19100 & ICSM Compliance
Assessment and remediation of spatial datasets against ISO 19100 series standards and ICSM Survey Practice guidelines. Metadata completeness checking and standards gap reporting.
CRS Management
Coordinate Reference System audit, transformation, and documentation. GDA94/GDA2020 transformation, MGA zone validation, and vertical datum reconciliation for multi-epoch survey datasets.
FME Validation Workflows
Automated data validation pipeline design using FME. Multi-rule validation schemas, exception reporting, and remediation workflow development for survey data intake and ongoing QA.
Metadata Standards
ISO 19115/19139 metadata creation, validation, and catalogue integration. ANZLIC metadata schema compliance and GeoCat-compatible metadata export for government data catalogues.
QA Documentation
Survey accuracy report production, data quality statements (DQS), and compliance certificates for project handover and regulatory submission.
