Cadcorp

Cadcorp is a British geographic information system (GIS) software company headquartered in Stevenage, Hertfordshire. Established in 1991, the company develops software for managing, analysing, publishing and integrating spatial information. Its principal technology platform is Cadcorp SIS, or Spatial Information System, which has been offered in desktop, server, web-mapping, cloud-hosted, developer-tool and specialised-application forms. The company began with Wincad, a Microsoft Windows-based computer-aided design product. Cadcorp sold all rights to Wincad in 1994, after which it concentrated on geographic information systems. The first version of Cadcorp SIS was released in 1995, marking the strategic shift that defined the company. Cadcorp subsequently built a business around spatial data management, GIS analysis, web mapping, application development and sector-specific workflows rather than around a single consumer-facing software product. Cadcorp's customer and market focus has traditionally been professional and institutional. Documented application areas include local, municipal and central government; emergency services; land and property; insurance; oil and gas; utilities; maritime operations; environmental management; and national mapping agencies. The company has also maintained a network of distributors and value-added resellers outside the United Kingdom, giving it an international route to market while retaining a British headquarters and strong UK public-sector orientation. Interoperability has been a central part of Cadcorp's technical positioning. The company has been a member of the Open Geospatial Consortium since 1997, and versions of Cadcorp SIS have achieved compliance in areas including Simple Features for OLE/COM, Grid Coverage Service, Coordinate Transformation Service, Web Map Service and Web Feature Service. The platform also supports geospatial standards and formats such as Web Map Context Documents, Geography Markup Language, Simple Features and Web Coverage Service. This standards-oriented approach is intended to help customers combine spatial information with existing databases, mapping services and enterprise systems. Cadcorp has also developed integrations with important UK geospatial data infrastructure. Its SIS platform supports direct links to the Ordnance Survey Data Hub and provides guidance for using the OS Features API, OS Maps API and OS Vector Tile API. These capabilities include support for British National Grid and Web Mercator-related coordinate and mapping structures. In 2020, Cadcorp expanded its product range with SIS ETL for extract, transform and load workflows and extended its cloud services to include SIS Desktop. The company completed a management buyout in May 2015, becoming privately controlled following that transaction. In August 2025, NEC Software Solutions UK completed the acquisition of Cadcorp. The acquisition places Cadcorp within the NEC software organisation while preserving its identity as a specialist GIS technology business. Cadcorp's current proposition is therefore best understood as enterprise geospatial software for organisations that need configurable spatial data management, mapping, analysis and integration across operational and public-service environments.

Cadcorp was established in the United Kingdom in 1991. Its initial product was Wincad, a computer-aided design system designed for Microsoft Windows. The company sold all rights to Wincad in 1994. Subsequent development and maintenance were later associated with Informatix and its UK subsidiary under the MicroGDS name, with development and maintenance eventually ending in March 2013. After divesting Wincad, Cadcorp redirected its activities toward geographic information systems. The first release of Cadcorp SIS, short for Spatial Information System, appeared in 1995. SIS became the foundation of the company's product and market strategy, supporting the management, analysis, publication and integration of geographic information for professional users. Rather than pursuing a consumer mapping business, Cadcorp concentrated on organisations where spatial data forms part of operational, regulatory or public-service processes. Cadcorp's documented markets include local and central government, emergency services, land and property, insurance, oil and gas, utilities, maritime operations, environmental management and national mapping agencies. The company developed an international distribution and value-added-reseller network while remaining based in Stevenage, Hertfordshire. Its institutional orientation was reinforced by technical and industry relationships, including Microsoft SQL Server spatial partnership, Ordnance Survey licensed developer status and membership of the UK Association for Geographic Information. Interoperability and open standards became important elements of Cadcorp's development. The company joined the Open Geospatial Consortium in 1997. In 2004, technical director Martin Daly received the OGC Kenneth G. Gardels Award for contributions to the OGC vision of integrating geographic information into information systems. Cadcorp SIS subsequently gained certification in several OGC interoperability categories, including web mapping, web feature services, coordinate transformation and grid coverage. The platform also implemented support for a range of related geospatial standards and representations. The SIS product family broadened over time. It became available as desktop software, server technology, web-mapping functionality, cloud-hosted services, developer tools and specialised applications. In 2020, Cadcorp introduced SIS ETL as a product for extracting, transforming and loading spatial data. During the same year, it expanded its cloud services to include SIS Desktop. Cadcorp also continued supporting Ordnance Survey data through direct connections to the OS Data Hub and documentation for the OS Features, OS Maps and OS Vector Tile APIs. These integrations addressed the needs of UK users working with British National Grid and web-based mapping coordinates. In May 2015, Cadcorp's leadership team completed a management buyout. The transaction maintained the company as a private specialist software provider. In August 2025, NEC Software Solutions UK completed the acquisition of Cadcorp. This changed the company's ownership context, placing its GIS capabilities within NEC's software portfolio, while the Cadcorp name and specialist geospatial focus remained relevant to its market identity.
