A scalable set of utilities for managing Ordnance OS MasterMap Topography Layer, Highways Network, Integrated Transport Network™ (ITN) Layer, Address Layer 2 and Imagery Layer data, designed to meet different user requirements


Delivered with Cadcorp SIS Desktop at no extra cost, Cadcorp SIS OS MasterMap Manager supports Microsoft Access MDB files, OS MasterMap Database (“ODB”) files, Microsoft SQL Server, PostGIS, and Oracle® databases. For less demanding applications, Cadcorp SIS also provides the ability, as standard, to read and display native OS MasterMap data, on-the-fly, as ‘flat files’. OS MasterMap Manager performs initial loads of OS MasterMap Topography Layer data directly from Ordnance Survey supplied data without translation, and also manages change-only updates.

Cadcorp SIS Network Manager loads initial supply of OS MasterMap Highways Network data including Road Routing Information (RRI) into a Cadcorp topological file format, for further route-finding, analysis and display.

Cadcorp SIS OS MasterMap Address Layer 2 Manager loads initial supply of OS MasterMap Address Layer 2 data into Microsoft Access MDB files, OS MasterMap Database (“ODB”) files, Microsoft SQL Server, PostGIS, and Oracle databases for gazetteer, query and display. OS MasterMap Imagery Layer data can be loaded directly from Ordnance Survey supplied data.

Cadcorp SIS – OS MasterMap for the enterprise

Enterprise users of the Cadcorp SIS product family are able to select from a scalable range of RDBMS systems for managing OS MasterMap, including Microsoft SQL Server, PostGIS, and Oracle databases.

OS MasterMap Manager offers the following features and benefits for the user:

  • Removes the need for middleware
  • Delivered with SIS Desktop at no extra cost
  • Swift performance
  • Theme Selection
  • Filter Creation
  • Easy-to-use Wizard
  • Batch automation
  • In-process monitoring and reporting
  • Change only update
  • Can be used by DBAs and GIS professionals alike

The RDBMS approach allows for the management of large volumes of OS MasterMap data in a multi-user environment. Cadcorp SIS also supports multi-user direct read and write to Microsoft SQL Server, PostGIS and to Oracle  databases without the need for additional middleware.

Cadcorp SIS – OS MasterMap for the desktop

For users simply interested in taking small amounts of OS MasterMap data into a system, Cadcorp SIS provides the ability to read and display OS MasterMap data direct from the native Geography Markup Language (GML) data files. Using this method, OS MasterMap is loaded into system memory and can then be viewed, queried, manipulated and printed.

OS MasterMap Database (“ODB”)

An OS MasterMap Database (“ODB”) is a spatial database encapsulated in a single file that can handle anything from a single OS MasterMap chunk, right up to national coverage. ODB files are supported by the Cadcorp SIS OS MasterMap Manager product and are of benefit to users who want to use large volumes of OS MasterMap data without having to invest in database server technology and management resources, and for remote or mobile users.

ODB files also extend OS MasterMap management options for the small and medium-sized enterprise or local authority that does not want to invest immediately in a relational database management server (RDBMS), or to be constrained by the 2 GB file size limit associated with Microsoft Access 2000.

Cadcorp SIS Network Manager

Cadcorp SIS Network Manager is a standalone application designed to load initial supply of OS MasterMap Highways Network data into a link and node network in a Cadcorp file format, maintaining the topological link/node relationships.

These options include:

  • Applying RRI to the network, eg. no entry, one way, mandatory turn etc
  • To globally apply ‘no U-Turns’ to the network to prevent route-finding from doubling back down a link
  • Transferring road names onto the network so that each link contains road name information

Network Manager is intended to support route planning applications across a wide range of sectors such as planning, monitoring and analysis, asset management, transport, logistics and distribution. It also includes support for Export to OSRM databases.

OS MasterMap Interoperability

Once loaded into an RDBMS, MDB or ODB file, OS MasterMap data is accessible from the entire Cadcorp SIS product family, including Cadcorp GeognoSIS® which is certified compliant for both Web Map Service (WMS) and Web Feature Service (WFS), and is certified Open Geospatial Consortium, Inc. (OGC) compliant. OS MasterMap data can be served to any third party GIS that contains an OGC W*S client implementation, thus maximising interoperability and data sharing between and within organisations. Cadcorp SIS Desktop Express is a free application available from Cadcorp. Amongst other things, it can browse geographic data including OS MasterMap data, served by OGC W*S services.

In order to further enhance interoperability, the Cadcorp GeognoSIS WFS server implementation serves any OS MasterMap Topography Layer data loaded using Cadcorp SIS OS MasterMap Manager using the native GML Application Schema – arguably the most widely supported GML Application Schema in the world.
