Processing of
spatial data

Handling, analysing and transforming your geospatial data to draw real insight from it.

Our approach

Your data, turned into decisions.

Whether for advanced analysis, simulation of complex scenarios or visualisation of geospatial data, our team uses leading tools to turn your data into performance and innovation.

Processing is written as reproducible chains rather than run by hand: format conversion, topology checking, enrichment and loading into a PostgreSQL / PostGIS database. The processed data then feeds your mapping applications.

Tools

Processing you can repeat

Spatial ETL

FME · bespoke scripts

The processing chains are written as reproducible scripts: one dataset goes in, a compliant dataset comes out. The same process can be re-run at every update, with no manual rework.

  • Format conversion
  • Batch processing
  • Automated re-runs

Database

PostgreSQL · PostGIS

The data is structured in a spatial database, with indexes, constraints and version control. This is the foundation the map portals and business applications rest on.

  • Modelling
  • Spatial queries
  • Version history

Frequently asked

What we get asked most often

What is ETL processing applied to spatial data?
ETL stands for Extract, Transform, Load : pull the data from its source, transform it against defined rules, then load it into the target system. Applied to spatial data, the work also covers geometry, projection and topology, not just attributes.
When is a script better than doing it by hand?
As soon as the operation repeats. A one-off conversion can be done by hand; a monthly update, an import from a partner or a pre-publication check are all better automated. The script fixes the rule and removes the variation between two runs.
Do you work with proprietary formats?
Yes. The processing chains handle the common GIS and CAD formats, open and proprietary alike. Migrating from a legacy system to an open solution is one of the most frequent requests we get.
What does topology checking cover?
Verification of geometric consistency: unclosed polygons, overlaps, gaps between adjoining parcels, invalid geometries. These faults go unnoticed by eye and break area calculations and spatial analysis alike.
Do you take on old or poorly structured data?
It comes up often. The work covers assessing what exists, defining the target model, converting, then checking the results. Data that cannot be recovered is identified and documented rather than patched on guesswork.
What happens to the data once processed?
It can be delivered as is, loaded into your existing database, or published in a map portal. Processing is rarely an end in itself: it prepares the data for publication or for operational use.
