Overview
What We Deliver in Spatial Data Management
Effective spatial data management is the foundation of any successful GIS program. TANGIS designs and implements Spatial Data Infrastructures (SDIs) that give organisations control over their geospatial assets — from data modelling and schema design through to metadata catalogues, data governance policies, and quality assurance frameworks. We are experienced with INSPIRE, ISO 19115, and national SDI standards.
Industries Served
Challenges We Solve
Data Silos
Geospatial data is scattered across departments in incompatible formats with no central governance or quality control.
No Metadata Standards
Without structured metadata, spatial data is undiscoverable, misused, and its provenance cannot be established.
Data Quality Issues
Legacy datasets contain topological errors, outdated attributes, and inconsistent coordinate reference systems that undermine analysis.
Compliance Requirements
Government organizations must meet national and international SDI standards but lack the technical expertise to implement them.
Our Approach
How We Deliver Spatial Data Mgmt
Data Audit
We conduct a comprehensive inventory of all spatial data assets — format, coordinate system, accuracy, currency, and governance status.
SDI Architecture Design
We design a spatial data infrastructure architecture matched to your organisational structure, technology stack, and long-term data management requirements.
Data Migration & Cleaning
We migrate data into standardised schemas, resolving topological errors, coordinate mismatches, and attribute inconsistencies.
Metadata Implementation
We build a metadata catalogue using ISO 19115/19139 standards, making your spatial assets discoverable and INSPIRE-compliant.
Governance & Training
We establish data governance policies, quality control workflows, and train your team to maintain standards independently.
