The dataset is structured into both geographic areas and thematic layers. The Great Britain dataset is divided into 100km by 100km tiles based on the National Grid. The data for each geographic area is stored in layers or themes. Each layer contains point, line or area data representing a group of map features. There is an additional layer containing textual annotation which is itself divided into sub-categories.
All layers are independently selectable.
However, the information contained in these pages is not intended as a guide to ArcView, and those wishing to progress beyond the basic functions of the software are encouraged to read ESRI's own documentation and user guides. All the data is held on the Sun E6500Superserver at Manchester Computing, permitting coverages to be created instantaneously with no need to import data. This enable theme layers to be accessed across all coverage tiles without having to load each tile manually. Access to the Bartholomew data is restricted to registered users only.
