Spatial Data Quality is vital for all organisations, but for Commercial Data Providers it is even more important as it underpins their flagship products and drives their market reputations. The high levels of data quality that are achieved by commercial data providers can only be achieved using 1Spatial solutions such as Radius Studio.

Data providers' customers also have a requirement for managing the quality of their own data which is used in conjunction with the master data from these providers. The high level of quality that are achieved in the master data allows customers to check, align and correct their data against it. 1Spatial solutions focus on auditing, discovering and correcting data, particularly by comparing against accurate master datasets.

Typical data errors that are encountered are:

1) Geometric errors. These can be found by looking at a single feature in isolation, and include items such as:

• Spikes
• Duplicate vertices
• Kick-backs
• Self-intersections
• Bow-ties
• Small features

2) Topological errors: These are problems within the relationships between features and include items such as:

• Overlaps
• Gaps
• Overshoots
• Undershoots
• Misalignments

 3) Business rules errors: These are problems which can only be identified from more detailed knowledge expressed as business rules, for example:

• Routes must be within a land polygon, unless they are flagged as a ferry, tunnel or bridge
• Buildings at level 0 must fall within a city block polygon
• A water pipe must have either a valve, stop cap or connector at both ends.

 These types of errors can affect the business process that are built on the data. They can lead to wrong or badly-informed decisions being made or can cause software problems within the information systems that process the data. By detecting and fixing these data problems,  organisations can build reliable automated processes which can improve the services they deliver and allow them to streamline difficult or costly manual tasks.
