“ The Radius Topology Wrappers help simplify the geometric cleaning and
structuring of our spatial layers. This can reduce a process that can
take hours to do manually, to a matter of minutes. ”

Radius Topology™ acts as both a data cleaner and a ‘gatekeeper’ by cleaning existing data and only allowing clean data to enter the Oracle Database - a crucial requirement for enterprise-wide data management. The extra information managed by Radius Topology allows precise and ultra-fast techniques for analysing, auditing and enhancing your data within the database through automation. You can realise a massive return on investment by automating difficult or costly processes.
Who is it for?
Any organisation that manages spatial data in markets such as: Transport, Utilities, Local Government, Central Government, Defence, Mapping Agencies
You can be more confident about the quality of your data and therefore the accuracy and reliability of those services that use it. You can also get real return on your investment in that data by extracting additional information from it and enabling you to improve your business processes.
Sample Implementations
MidCoast Water, Australia
for ensuring quality and auditing asset data
Surrey Heath Borough Council, UK
to ensure consistent quality of land parcel data and assist with positional accuracy improvement

to detect and correct historical errors, and enable faster spatial querying
Colchester Borough Council, UK
to clean data before PAI, and after used to validate and continually maintain the data
Property Registration Authority Ireland
to check the output from a datacapture exercise against the Ordnance Survey basemaps
New and Enhanced Features
Radius Topology Wrappers
Radius Topology Wrappers are standard components deployed with Radius Topology and provide simple user interfaces to help you to get the most value from your topology data.
Radius Topology Wrappers include:
Quickstart: A generic tool that provides a quick way to set up and structure a set of tables and is often used as the first step before running other Wrappers.
BLPU Extent Creator: Generates BLPU (Basic Land and Property Unit) Extent polygons from OS MasterMap® and a set of BLPU points. This provides massive savings in the time and effort required to create the extent polygons, by creating the majority of them automatically. By recording the extent of the BLPUs rather than simply a single point, organisations can greatly increase their productivity and service offerings, for example automating land charge searches.
Data Cleaning: Detects and/or removes geometric errors such as spikes, duplicate vertices or small holes in polygons. Functions can be operated either in bulk or by adding a trigger to the tables automatically to maintain clean data during editing.
PAI (Positional Accuracy Improvement) Audit: This Wrapper compares the ‘before shift’ and ‘after shift’ data and alerts the user whenever a feature has changed its shape or its relationship to the base mapping or other features. This provides a powerful and accurate way of quantifying the results of the shifting process.
Network Conflation: This Wrapper creates live views of errors in linear data, allowing users to find gaps, dangles, splits, overlaps and mismatches within one or more data layers. This increases the efficiency of data editing operators and delivers powerful data quality auditing.
Polygon Conflation: This Wrapper creates live views of holes, overlaps or mismatches between polygon layers. This increases the efficiency of data editing operators and delivers powerful data quality auditing.
Change-only-Update Support: Enables Radius Topology work in a different way when bulk changes are applied to a topologically structured base dataset. This prevents the data from being snapped until all changes have been applied and improves performance. It also leaves affected asset features unstructured, allowing you to manually inspect them before restructuring.
Radius Topology is currently used by customers in Utilities, Local Government and Central Government market sectors.
