About Landmark Data

Landmark was founded on the principle that combining and consolidating information, would not only improve the availability of data, it would create new information providing new solutions for old problems.

Agreements with a number of public and private organisations, in conjunction with a series of internal data capture initiatives has enabled Landmark to build one of the most extensive databases of its kind.

All the data held is constantly updated and cross-referenced to ensure its accuracy and reinforce the reliability on which our clients depend. Each item of data is geographically coded so that every report generated is enhanced by the ability to locate features on both current and historical maps.

This mammoth effort is supported by a team of over 25 dedicated data and technical specialists within our Exeter offices, some with over ten years experience in this type of skilled technical work. For certain types of data collection the services of Landmark's offshore partner are called upon to provide scalability for larger data collection projects. The diagram to the right illustrates the process of how data is captured, refined and incorporated into our database.

Data Statistics

Landmark regularly maintains well over 150 diverse data sets covering current and historical data. These range in scale and complexity from the Ordnance Survey MasterMap® Topographic layer containing over 400 million features to marine nature reserves that can be counted on one hand.

Much of the data is supplied in electronic format, however, on occasion is it only available on paper and has to be captured to allow it to be added to the database. Over the past ten years, within a joint venture agreement Landmark has captured over 1.2 million Ordnance Survey plans creating an unique historical archive, one of the largest of its type in Europe.

One of the key requirements of any data used by Landmark is a grid reference for each record so that it can be accurately plotted on a map. Much of the data that is routinely received does not have a grid reference. Over 75,000 records a month are found by using advanced address matching and geo-location techniques.
