Key Outcomes

National reference portalUnified

A single, authoritative entry point for spatial reference information across disciplines.

Computation performanceOptimized

Improved responsiveness for heavy geospatial calculations through indexing and caching strategies.

Governance & auditabilityStrengthened

Standardized metadata, versioning practices, and access control for operational reliability.

The Challenge

Delivering a High‑Integrity Spatial Reference Platform at National Scale

The platform must support complex geodesy/spatial operations while ensuring data consistency, traceability, and a user experience that works for diverse stakeholders.

High‑complexity spatial computations

Accuracy, validation, and repeatability are mandatory for geodesy and reference calculations.

Multi-source data integration

Datasets and services come from different producers with varying standards and update cycles.

Operational demands

The system requires role-based access, audit trails, and stable performance under sustained usage.

Our Approach

Enterprise GIS Architecture Built for Accuracy, Performance, and Operations

Sintesa executed a discovery-led delivery: aligning data standards, implementing core platform modules, optimizing geospatial workloads, and hardening the system for production operations.

Discovery, data audit, and standardization

Mapped sources, defined schemas/metadata, and established integration contracts.

Core portal and geospatial services

Implemented portal modules and computation services with clear API boundaries.

Performance & reliability engineering

Applied spatial indexing, caching, workload tuning, and monitoring baselines.

Security and operational readiness

Introduced RBAC, audit logging, and operational SOPs for multi-phase delivery.
