Core Responsibilities

Primary Functions

Plan, design and execute formal GIS audits across enterprise geodatabases, feature datasets, and map services to validate spatial accuracy, topology, attribute integrity, and schema compliance against organizational and regulatory standards.
Develop, document, and maintain repeatable QA/QC workflows and audit checklists that incorporate topology rules, attribute domains, coordinate system checks, and versioning best practices for ArcGIS and PostGIS environments.
Perform comprehensive spatial validation including edge matching, topology error detection, polygon/line/cadastre reconciliation, and positional accuracy assessments using GPS control points and survey deliverables.
Create and run automated quality-control scripts and ETL checks using Python (ArcPy), FME Workbench, SQL queries, and custom scripting to detect anomalies, outliers, and missing metadata across large spatial datasets.
Review and validate metadata against FGDC and ISO 19115 standards; ensure completeness of lineage, contact, projection, scale, accuracy, distribution, and access constraints for all published datasets.
Conduct attribute-level audits to identify coding inconsistencies, domain violations, null or default values, and to verify compliance with established data models and business rules.
Lead data reconciliation activities between source CAD, survey, LiDAR and derived GIS products, documenting transformations, reprojections, and generalization steps applied during ETL processes.
Produce clear, actionable audit reports and dashboards summarizing findings, severity levels, recommended remediation, and trend analysis for data quality KPIs; present results to technical teams and executive stakeholders.
Collaborate with GIS developers and database administrators to prescribe fixes for schema misalignments, spatial index issues, and performance bottlenecks discovered during audits.
Establish and enforce data acceptance criteria for new datasets, onboarding external vendor data, and contracted deliverables; validate vendor submissions against contractual SOW and SLA requirements.
Design and implement regression tests and version control checks to ensure that edits, merges, or topology repairs do not reintroduce historical errors or degrade data quality.
Coordinate and perform targeted field validation and ground-truth surveys to verify positional accuracy and attribute correctness for critical asset layers using GNSS equipment and mobile data collection tools.
Monitor and audit ArcGIS Online / Portal for ArcGIS content and services, ensuring published web maps, feature services and applications meet organizational security, sharing, and metadata policies.
Maintain and validate geodatabase integrity by running consistency checks, reconciling versions, repairing geometries, and applying data migration best practices during schema updates.
Work with procurement and legal teams to define technical acceptance testing criteria for geospatial data contracts; review vendor QA documentation and sample deliverables prior to payment or production ingestion.
Build and maintain a prioritized backlog of data remediation tasks, coordinate with data stewards to schedule fixes, and track closure of audit findings through to verification and sign-off.
Develop and deliver training, guidance notes, and data governance documentation for GIS users to reduce common data quality issues and promote consistent mapping and attribute practices.
Implement and monitor spatial data quality KPIs and SLAs, create automated alerts for threshold breaches (e.g., percent topology errors), and maintain a quality dashboard for continuous improvement.
Conduct peer reviews of mapping and analysis workflows, mentor junior GIS staff in QA methodologies, and establish a culture of data quality and reproducible workflows across teams.
Validate LiDAR processing outputs, digital elevation models (DEMs), and derived products for point density, vertical accuracy, and classification consistency in collaboration with remote sensing teams.
Evaluate and recommend tools, plugins, and third-party software that improve audit capabilities (e.g., quality assurance extensions, topology managers, data lineage platforms).
Ensure compliance with data privacy, licensing, and access controls during audits, including masking of sensitive attributes and verification of user roles/permissions in GIS systems.
Investigate and remediate data drift after bulk updates, migration, or historical data reprocessing; document change-control procedures and rollback strategies.
Maintain audit logs, version histories, and evidence packages to support regulatory inspections, funding audits, and contractual disputes relating to spatial datasets.
Support continuous integration/continuous deployment (CI/CD) practices for geospatial data pipelines by integrating QA steps into automated build and deployment processes.
Liaise with business stakeholders to translate audit findings into prioritized business risks and costed remediation plans that align with strategic objectives.
Stay current with industry standards (FGDC, ISO, INSPIRE where applicable), emerging geospatial technologies, and auditing best practices to update the audit program accordingly.

Secondary Functions

Support ad-hoc spatial data requests, forensic investigations, and exploratory spatial analyses to contextualize audit findings for stakeholders.
Contribute to the organization's geospatial data governance strategy, including policy development for data stewardship, metadata practices, and quality assurance frameworks.
Collaborate with business units to translate operational data needs into technical requirements for data quality, ingestion pipelines, and validation rules.
Participate in sprint planning and agile ceremonies with GIS development and data engineering teams to ensure QA tasks are prioritized and integrated into release cycles.
Assist procurement and vendor management teams during RFP evaluations by providing technical criteria for data quality and auditability.
Provide after-action reviews and lessons-learned summaries following major data migrations, system upgrades, or audit initiatives.
Facilitate cross-functional workshops to harmonize attribute schemas, domain definitions, and naming conventions across departments.
Maintain a library of audit templates, scripts, and reusable test cases to accelerate future audit activities and institutionalize best practices.
