OS MasterMap® Topography Layer optimised for ArcGIS Online & other GIS platforms

Our optimised vector tile packages are used by some of the largest utilities and infrastructure companies in the UK to deploy smart and intelligent digital maps to operations teams working on asset management and maintenance programmes. This could be in water, gas, electric, renewable energy, telecommunications, highways, rail, ports/airports and across environmental services where rapid response and reliable, efficient mobile applications are necessary to quickly capture and use information for decision-making.

Embedded data services and georeferencing tools from MGISS offer a cost-effective and seamless approach to data migration and governance of legacy data siloes to reconcile old, poorer-quality spatial data with a changing digital mapping estate. Products such as CADTransform can manage data interoperability between CAD and GIS.

Ordnance Survey National Geographic Database (OS NGD)

The OS NGD is a single store of ALL Ordnance Survey’s authoritative data for Great Britain. By 2027, NGD is expected to replace legacy datasets such as OS MasterMap Topography Layer and elements of AddressBase.

The OS NGD delivers the richer data you need for better analysis and our download service, OS Select+Build, makes it easier to find, package and analyse the data you need, such as address and building data for emergency planning.

OS NGD data is different from other OS products because it is accessed from one single source where you can find the data you need WITHOUT having to purchase and download whole datasets making it cheaper as well as faster to use. It also has a simpler data structure, designed to help answer questions and develop more intelligent solutions, with quicker loading and implementation.

Available data services:

  • OS Select+Build
  • OS NGD API – Features
  • OS NGD API – Tiles

Geographic data of Great Britain is structured into nine themes. Each theme is made up of one or more collections, which in turn have feature types. And if you just need specific features within a collection, for example Organisation Name within Built Address, OS Select+Build and the OS NGD API – Features allow you to access only this data.

Why buy OS Data Services from MGISS?

  • ETL Services (Extract, Transfer & Load) – We help convert and move OS data between common geospatial formats, relational databases, and even lightweight file formats used in field tools and mobile apps. Whether you’re working with shapefiles, geodatabases, or cloud storage, we ensure your data flows seamlessly across systems.
  • Geoprocessing Services – Including cookie-cutting, feature extraction and attribute filtering, our geoprocessing data services tailor complex datasets into precise, usable formats that align with your needs. For example, if you only need MasterMap data for a specific area or asset type, we’ll trim it down and deliver exactly what you need.
  • Caching OS Data (for Web & Mobile use) – This dramatically improves performance and user experience for field users—tiles load faster, and data consumes less bandwidth, which is vital when working in poor signal areas

What our customers think:

“Leveraging OS basemaps in to existing software was a really straightforward way to utilise what we already had in the business, but that had just never been put into GIS before!.”

Emma Morgan, Anglian Water (@One Alliance)

“I feel so much more confident now because everything’s there and it can flag and I can easily run reports, and we’ve got all the things we asked for, everything is build into the process.”

Helen Jacobs, Essex & Suffolk Water
