Collins Bartholomew takes the greatest of care in assuring the high quality of our data. The data is constantly being updated and revised, with an average of 40,000 name edits each year.
All our database updates are thoroughly researched by our highly dedicated in-house team of professional cartographers and information researchers.
We also use external experts, specialist organisations, official organisations, agencies, government departments and business offices to assist in the information gathering process.
Policy changes (e.g. international boundary changes, new country depiction, name changes) are informed by external experts. For advice on name forms we look to the PCGN (the UK government’s Permanent Committee on Geographic Names for British Official Use) and BGN (US Board on Geographic Names) plus of course local/country specific information. From this we would make our decision on the ‘de facto’ stance and apply geographical expertise to work out the details.
World Locate Premium is available as a standalone dataset that you can download and store locally, or it can be accessed via one of our secure web services. Whichever you choose, our licence fees are based on the number of concurrent users with fees staring from £1250 per annum.
