Geospatial engineering services cover the design, build, migration, and integration of GIS systems that utility, telecom, energy, and government operations depend on, not mapping projects. Still, the spatial data infrastructure that feeds operational systems, supports planning decisions, and drives field crew workflows.
Gnapi Technologies delivers geospatial engineering services across GIS strategy, solution architecture, network modelling, data migration, system integration, and ArcGIS and Smallworld implementation for enterprise clients in Canada, the USA, the UK, and globally.

For electric utilities and telecoms, GIS is not a mapping tool. It is the spatial backbone that feeds the Outage Management System (OMS), drives field crew dispatch, supports network planning, and provides the asset records that regulators require. When a utility cannot accurately trace a feeder in its GIS, outage restoration takes longer. When a telecom’s Physical Network Inventory does not reflect what is actually built, fibre planning decisions are made on incomplete data.
Gnapi’s geospatial engineering work starts with that operational context, understanding what decisions the GIS needs to support, what systems it feeds, and what the consequences of data quality failures are in practice. Enterprise GIS solutions are designed around those requirements, not around the map as an end product, which is what separates our Geospatial Engineering Services from generalist IT delivery.

Electric utilities in North America run primarily on GE Smallworld or ESRI ArcGIS Utility Network, with a significant installed base on both platforms. Gas operators tend toward Smallworld’s Gas Distribution Office module. Telecoms use Smallworld’s Physical Network Inventory module or custom-built OSS-integrated GIS platforms. Gnapi works across all of these environments.
Geospatial Engineering Services strategy defines the GIS architecture a utility or telecom should build toward platform selection, data model design, integration strategy, and migration sequencing. Solution architecture translates that strategy into a buildable technical design: the database schema, integration patterns, web services configuration, and deployment model.
Gnapi conducts cost-benefit analysis across platforms, Smallworld, ESRI ArcGIS, and hybrid architectures, so platform decisions are made on technical and operational grounds rather than vendor relationships or incumbent preference.
GIS network modelling builds a digital, connected representation of a physical network inside the GIS cables, pipes, conduits, nodes, and the connectivity between them- structured so the Geospatial Engineering Services Edmonton can answer operational questions: which customers are affected by a fault, which valves isolate a pipeline segment, which fibre spans are available for a new circuit.
We design and build network models for electric distribution, gas distribution, and fibre networks and validate them against as-built records before they go into production.
ArcGIS Utility Network is ESRI's enterprise GIS data model for electric and gas utilities, replacing the older geometric network model with a topology-based network that supports advanced tracing, subnetwork management, and integration with OMS and ADMS platforms.
Gnapi implements ArcGIS Utility Network from data model configuration through data migration, network topology validation, OMS integration, and editing environment setup. We also migrate utilities from legacy ArcGIS geometric network models and from other Geospatial Engineering Services Edmonton platforms, including Smallworld-to-ArcGIS migrations for utilities changing platforms.
GIS integration with OMS connects the GIS network topology to the Outage Management System, so when a fault occurs, the OMS can trace which network assets are affected, identify impacted customers, generate switching orders, and track restoration. The integration passes network topology data from the GIS to the OMS in a format the OMS can query and traverse.
We build GIS-OMS integration across both Smallworld and ArcGIS environments, and across multiple OMS platforms.
Geospatial data for large utilities and telecoms accumulates across decades, multiple source systems, inconsistent schemas, records that reflect how the network was built rather than how it operates today, and data quality issues that have compounded over years of manual editing and system migrations.
We manage data quality assessment, migration, schema rationalization, and ongoing governance programs. For large PNI migrations and utility network conversions, data management is typically the longest and highest-risk workstream in the program.
FME- Feature Manipulation Engine, developed by Safe Software, is a data integration and transformation platform that handles the conversion, routing, and quality checking of spatial and non-spatial data between systems. In a utility or telecom GIS environment, FME is used to build and maintain the integration pipelines between GIS and enterprise systems, OMS, ERP, work management, and asset management, where data formats, schemas, and update frequencies differ between systems.
Gnapi uses FME for data migration, ongoing integration maintenance, and data quality workflows across both Smallworld and ArcGIS environments.
We deliver geospatial solutions for government agencies and public sector clients land management systems, infrastructure mapping platforms, spatial analytics for regulatory functions, and GIS implementations for public utility oversight. Government GIS projects require attention to procurement compliance, data residency requirements, where data is stored and who can access it and security controls that differ from commercial utility work.
GE Smallworld and ESRI ArcGIS are both enterprise GIS platforms used by utilities, but they have different architectures, data models, and use patterns.
Smallworld uses a proprietary spatial database, the Magik programming language, and an alternative worlds versioning model that tracks all edits as pending changes until approved. It has been the dominant platform for large electric utilities and telecoms in North America and Europe for three decades.
ESRI ArcGIS Utility Network uses a geodatabase architecture, standard SQL databases, and Python/Arcade for customization. It is the current ESRI recommendation for utility Geospatial Engineering Services
and has a broader developer community and more integration tooling available.
Gnapi advises on platform selection and delivers on both.
A GIS consultant working for a utility typically covers some combination of: assessing the current Geospatial Engineering Services environment and identifying gaps; designing or redesigning the GIS data model to match operational requirements; managing data migration from legacy systems; building integrations between GIS and OMS, SCADA, or work management platforms; implementing or upgrading the GIS platform itself; and supporting the utility’s internal GIS team on specific technical problems they do not have in-house expertise to solve.
GIS migration timelines depend on three factors: the size and complexity of the existing dataset, the number of downstream systems that need to be re-integrated after migration, and the data quality of the source data. A utility moving from a legacy geometric network to ArcGIS Utility Network with a clean dataset and three integrations might be completed in 12–18 months. A telecom migrating a PNI dataset with significant data quality issues and ten downstream OSS integrations might take 24–36 months. Gnapi scopes each migration individually and provides timeline estimates based on the technical assessment of the source environment.
If you are planning a utility network GIS implementation, a data migration, a system integration, or need GIS consulting near me in or across North America, the first step is a technical conversation about what you are trying to build. Gnapi Technologies is based, Alberta, and delivers geospatial and engineering services across North America.

Geospatial engineering is the discipline of designing, building, and integrating GIS systems on which operational functions depend, not mapping or visualization projects, but the spatial data infrastructure that feeds OMS, supports network planning, drives field crew dispatch, and provides the asset records that regulators require. For utilities and telecoms, Geospatial Engineering Services work includes network modelling, data migration, system integration, and platform implementation.
Gnapi's primary platforms are GE Smallworld and ESRI ArcGIS Enterprise, including ArcGIS Utility Network. We also work with FME (Safe Software) for data integration, PostGIS for open-source spatial database work, and Oracle Spatial, where client environments require it. Platform selection is assessed per engagement based on the client's existing environment, operational requirements, and integration landscape.

data model for electric and gas utilities, replacing the legacy geometric network model with a topology-based network that supports advanced tracing, subnetwork management, and integration with OMS and ADMS platforms. It uses a geodatabase architecture with standard SQL databases and supports Python and Arcade for customization. Gnapi implements and migrates to the ArcGIS Utility Network for utility clients across North America and the UK.
GIS network modelling creates a topology-valid digital representation of a physical network inside the GIS, structured so the GIS can answer operational questions such as which customers are affected by a fault, which valves isolate a pipeline segment, or which fibre spans are available for a circuit. Without a valid network model, GIS is a map of assets. With a valid network model, GIS becomes the spatial engine that drives OMS, field crew dispatch, and network planning decisions.
GIS integrates with an OMS by passing network topology data on how assets connect and what their current state is from the GIS to the OMS in a format the OMS can query and traverse during an outage event. The integration must reconcile the different data models, update frequencies, and network representations used by the GIS and the OMS. Gnapi builds these integrations across Smallworld and ArcGIS environments and across multiple OMS platforms.
Spatial data management covers the processes of assessing, cleaning, migrating, and governing geospatial datasets in enterprise GIS environments. For utilities and telecoms, this includes data quality assessment against the network model rules, schema rationalization across source systems, migration into the target GIS platform, and ongoing governance to prevent data quality degradation after go-live. Poor spatial data quality in a production GIS propagates errors into every system that consumes the data.
For electric utilities, Gnapi delivers Smallworld and ArcGIS Utility Network implementations, Electric Office customization, OMS and ADMS integration, feeder network modelling, and data migration from legacy GIS platforms. For gas distribution operators, we deliver Gas Distribution Office configuration, pipeline network modelling, and SCADA integration. These are operational systems, not mapping projects. Our work covers the full stack from data model through integration.
Yes. For telecoms, Gnapi delivers Physical Network Inventory (PNI) design and migration, OSS integration, fibre network modelling, and GIS platform upgrades. Accurate PNI is the foundation for fibre rollout planning, network asset management, and OSS-driven operations. We work on Smallworld-based telecom GIS environments and on custom-built PNI platforms that integrate with BSS and OSS systems.
Gnapi pairs onshore technical leads in Edmonton, the USA, or the UK with offshore engineering teams in our India delivery centers in Bengaluru, Hyderabad, and Trichy. The two teams operate as a single integrated delivery unit on client tooling and within client processes. This model allows us to staff large, multi-year GIS programs, utility network migrations, PNI rebuilds, and OMS integration programs at competitive rates without reducing technical seniority on the engagement.
The first step is a technical scoping conversation, not a sales presentation. We ask about your current GIS environment, what you are trying to achieve, which systems the GIS needs to integrate with, and what your data quality situation looks like. From that conversation, we provide an honest view of scope, approach, risk, and team composition before any formal proposal. Contact Gnapi Technologies to book a scoping call with one of our GIS engineers.
