About SEPM

25+ years of GIS data translation

The story of SEPM — who we are, how our products evolved, and where we are taking X-Translator next.

Who we are

Connecting systems through spatial data.

Software Engineering and Project Management (SEPM) is a Swiss software engineering company specializing in spatial data integration, translation, and migration.

For more than two decades, SEPM has helped utilities, infrastructure organizations, and engineering teams exchange spatial data across different systems, formats, and technical environments.

From specialized Smallworld GIS integrations to modern, open-platform data workflows, our work focuses on making complex data exchange more reliable, practical, and efficient.

GIS engineering: Deep experience with Smallworld GIS and complex spatial data models.
Data interoperability: Software and interfaces connecting GIS, CAD, spatial databases, and specialized industry systems.
Migration and integration: Practical engineering expertise for moving, transforming, and validating data across environments.

Our evolution

One foundation. Evolving capabilities. New possibilities.

Our products have evolved alongside the spatial data environments they serve.

What began as a specialized translation tool for Smallworld GIS developed into a mature data exchange solution and is now expanding into a standalone platform for open GIS and CAD workflows.

Each generation builds on the engineering experience of the one before it.

2000–2005
Historical product
SEPM Translator · The foundation
Where the journey began
SEPM Translator was our first data exchange product for Smallworld GIS. It enabled users to import and export GIS data in formats such as Shapefile, MIF/MID and DXF, providing practical tools for everyday data exchange.
- Early Smallworld GIS integration
- Support for established exchange formats, including Shapefile, MIF/MID, and early DXF
- Early experience with complex spatial objects and automated translation workflows
As customer requirements grew, SEPM developed the next generation of its translation technology.

2005–2025
Smallworld integration · data exchange
SEPM X-Translator for Smallworld · Smallworld integration
From data conversion to integrated GIS workflows
Introduced in 2005, SEPM X-Translator became a comprehensive data exchange solution for Smallworld GIS. Built around the Smallworld Application Framework and the TFM/TFD architecture, it progressively expanded to support DWG/DXF, spatial databases, open GIS formats and specialized utility workflows.
- TFM/TFD architecture and model-aware translation
- Extended CAD/GIS formats, including DWG/DXF, PostGIS and GeoPackage
- Automated transfers, reusable configurations and Simple GUI
- Specialized interfaces such as NEPLAN, ISYBAU and INTERLIS/SIA405
Building on this experience, SEPM began extending its translation technology beyond the Smallworld runtime.
03
2026 onwards
Standalone spatial data translation
SEPM X-Translator · Standalone and open-platform workflows
Beyond Smallworld – a new generation
The latest generation extends SEPM's translation expertise into a standalone desktop application. It enables direct data exchange between supported external formats—including workflows involving GeoPackage, PostGIS, and CAD data—without requiring an active Smallworld runtime for those standalone workflows. A modern mapping workspace, reusable transfer configurations, and integration with mySEPM bring greater flexibility to the established translation approach.
- Standalone workflows independent of an active Smallworld runtime
- Direct exchange between supported external formats
- Modern source-to-target mapping and reusable configurations
- Integration with mySEPM for account and subscription management

Our portfolio

A growing portfolio, built around real-world workflows.

Spatial data challenges rarely exist in isolation. Alongside X-Translator, SEPM has developed products and interfaces for raster data, infrastructure networks, specialized industry formats, and the management of software access. Together, these solutions address different parts of the data integration and engineering process.

Our approach

Experience that moves data forward.

Today's spatial data environments are more connected — and more diverse — than ever. Organizations need to exchange information between established GIS platforms, CAD applications, spatial databases, and newer open-platform tools. SEPM combines its experience with complex spatial models and production workflows with modern software architecture to make these connections easier to establish, automate, and maintain.

Interoperability across environments

Connect established Smallworld systems with CAD applications, spatial databases, and open GIS formats through supported translation workflows.

Reliable, model-aware transformation

Go beyond basic file conversion by mapping source and target models, managing attribute relationships, and preserving supported geometry and styling information.

Flexible workflows and automation

Support different working environments — from interactive desktop tools and Smallworld-integrated interfaces to automated processing and standalone translation.

People & community

Built by people who understand the work.

Behind every generation of SEPM software is experience gained from real projects, close collaboration with customers and partners, and a continued focus on solving practical engineering challenges. Our work develops through the people who design, build, test, implement, and use these solutions.

Sharing knowledge. Learning from real workflows.

SEPM stays connected to the spatial technology community through user-group conferences, technical presentations, product demonstrations, webinars, and partner activities. These exchanges create opportunities to share practical knowledge, demonstrate new capabilities, and understand the challenges customers and integration partners face.

Conferences & community

Upcoming conferences and community events

More events on the way

We plan to add SEPM Office Hours / Q&A sessions and requirements and feedback meetings with customers and partners.

What's next

The next chapter of spatial data integration.

Spatial data environments continue to evolve, bringing new formats, more complex models, and increasing expectations for automation and interoperability. SEPM's next chapter builds on its experience in data translation and engineering, extending its tools and workflows to support new platforms, more flexible transformations, and increasingly connected systems.

Open-platform interoperability

Continue expanding workflows that connect CAD, open GIS formats, spatial databases, and established enterprise GIS environments.

Smarter transformation and automation

Develop more flexible mapping, reusable configurations, and automation capabilities that reduce repetitive work and help manage complex data transformations.
