Duplicated records
Address, street and property records can overlap when teams inherit multiple source systems.
Why spatial data matters during reorganisation
Organisational change can expose fragmented spatial data, duplicated gazetteers, legacy GIS platforms and service data dependencies. Many council services rely on shared address, map and case-management data, so consolidation work needs to be planned carefully.
The dependencies often include LLPG and LSG data, UPRNs and addresses, GIS layers, planning and building control data, land charges information, TRO and highways data, public-facing portals, reporting and integrations with other business systems.
Common risks
Inconsistent standards
Different naming, coding, geometry and update practices can make trusted reporting harder.
Unsupported legacy GIS
Older platforms may not provide the access, security or integration model needed for the new organisation.
Unclear ownership
Layers, datasets and extracts need named owners before they can be improved or retired.
Case-management dependencies
Planning, building control, land charges and other statutory services may rely on the same address and spatial data.
Public search issues
Changes to datasets can affect portals, public search, reporting and external links.
Rushed migration decisions
Moving data before checking quality and dependencies can lock old problems into a new platform.
Weak data checks
Consolidation needs practical data-quality checks, not just file transfers.
Where StatMap can help
Gazetteer consolidation
Review LLPG, LSG, UPRN and addressing structures before migration or merger work begins.
Spatial data audit
Identify important layers, owners, formats, quality issues and business dependencies.
GIS platform consolidation
Plan how browser-based GIS, shared mapping and service-specific tools should fit together.
Migration planning
Map source systems, data formats, priorities and risks so implementation work is better sequenced.
Service dependencies
Assess planning, building control and land charges data implications before operational changes are made.
Portal implications
Review public-facing search, reporting and map services that rely on consolidated data.
Integration planning
Plan APIs, extracts, data feeds and synchronisation between spatial systems and business applications.
Implementation support
Work with specialists who understand local authority spatial data, statutory workflows and hosted data services.
A practical approach
- 1
- Discover
- Identify source systems, datasets, owners, integrations and public-facing dependencies.
- 2
- Assess
- Check data quality, duplication, geometry, formats, standards and operational risks.
- 3
- Prioritise
- Separate critical statutory workflows from lower-risk datasets and future improvements.
- 4
- Cleanse
- Prepare address, street, spatial and service data before migration or platform changes.
- 5
- Migrate
- Move data in a controlled way with checks, fallbacks and clear acceptance criteria.
- 6
- Integrate
- Connect consolidated data to GIS, case management, portals, reporting and business systems.
- 7
- Support
- Help teams operate, maintain and improve the new data foundations after go-live.
Why StatMap
StatMap works with local authorities on GIS, gazetteer management, case-management workflows, public portals, data migration and hosted spatial data services.
That combination matters during consolidation work because the same data often supports several services at once. Address records, street data, map layers, planning constraints, land charges, reporting outputs and public portal searches all need to be understood as connected operational dependencies.
StatMap can help councils shape a practical plan that reflects LLPG and LSG requirements, spatial data quality, hosted OS mapping options, integration needs and the move toward browser-based access.
