Geographic Data Services for Government
From post code assignment for new development areas to full address data audits for existing municipal systems — we provide the geographic data services that public sector organisations depend on.
Post Code Assignment
Accurate, validated post code assignment for new addresses, development areas, and unmatched address records — delivered to Royal Mail PAF and BS7666 standards.
About this service
Post code assignment is our core service. We assign accurate, validated post codes to new addresses, newly developed areas, and existing address records that are missing or incorrectly coded. Every assignment is cross-referenced against Royal Mail PAF sector boundaries, Ordnance Survey MasterMap building footprints, and local authority administrative boundaries.
Typical use cases
- New residential and commercial developments requiring post code allocation before occupation
- Local authority address registers with missing or incorrect post codes
- Emergency services address databases requiring validated post code coverage
- Planning and land registry datasets requiring post code attribution
- Validated post code dataset
- Accuracy rate certificate (target 99.7%)
- QA audit trail
- Data dictionary and metadata
- Integration guide
GIS Mapping & Spatial Analysis
Bespoke GIS mapping and spatial analysis for planning, infrastructure, and public service delivery — built on authoritative OS and local authority datasets.
About this service
Our GIS mapping service produces bespoke geographic datasets and spatial analysis outputs for government and municipal clients. We work with Ordnance Survey MasterMap, local authority boundary data, and client-supplied datasets to produce mapping products that support planning decisions, infrastructure management, and public service delivery.
Typical use cases
- Planning authority boundary mapping and land use classification
- Infrastructure asset mapping for highways, utilities, and public estates
- Service area analysis for emergency services, health, and social care
- Environmental and flood risk zone mapping for planning applications
- Bespoke GIS dataset (GeoJSON / Shapefile / GeoPackage)
- Attribute schema and data dictionary
- Spatial accuracy report
- INSPIRE-compliant metadata record
Address Data Audit & Remediation
Independent audit of existing address and post code datasets — identifying errors, gaps, and non-compliant records, with a structured remediation plan.
About this service
Many local authority and public sector address datasets contain accumulated errors: duplicate records, missing post codes, incorrect geocodes, and non-compliant address formats. Our audit service provides an independent, structured assessment of your existing data — quantifying the problem, identifying root causes, and producing a prioritised remediation plan.
Typical use cases
- Local authority address registers ahead of system migration or upgrade
- Emergency services databases requiring accuracy certification
- Housing and planning datasets ahead of public consultation or publication
- Any public sector dataset requiring BS7666 compliance verification
- Audit report with error register
- Accuracy metrics by field and record type
- Prioritised remediation plan
- Optional: remediated dataset with before/after comparison
Working with NAVLOGICA
Our engagement model is designed for public sector procurement — straightforward scoping, clear deliverables, and documented outputs at every stage.
Initial Consultation
A no-obligation technical consultation to understand your data requirements, existing systems, and project timeline. We can work with your procurement team to scope a compliant engagement.
Scoping & Proposal
We produce a detailed project scope, methodology statement, and fixed-price proposal. All proposals include a clear deliverables schedule and acceptance criteria.
Data Exchange
Secure transfer of source data via your preferred method — SFTP, encrypted file transfer, or direct system integration. We sign your data sharing agreement before any data is exchanged.
Processing & QA
We process your data through our validated pipeline and QA framework. You receive progress updates at agreed milestones, with early sight of any issues or edge cases.
Delivery & Sign-off
Validated outputs are delivered with full documentation. We support your team through integration and provide a 30-day post-delivery support window for queries.
Discuss Your Data Requirements
Tell us about your project and we will provide a no-obligation assessment of how we can help. Most initial consultations can be arranged within five working days.
