GIS databases

This website is intended to give easy access to maps and data of general interest. For example, clickable maps of port infrastructure, maps showing forecast network flows and matrices of demand at country-country level.

If you are carrying out analytical work needing more detail, such as greater spatial detail or GIS datasets so that you can create more specific maps, the GIS datasets and databases created by the Infrastructure Contract are also available. This data is provided in Microsoft Access MDB format, GIS datasets are ArcGIS personal geodatabases (also stored in MDB format) intended to be useable with ArcGIS version 8.3 or higher.

Dataset sub-themes

Infrastructure networks (1.4MB): ports, airports, roads, railways

Network flow forecasts (7.3MB)

Demand data: origin-destination demand (6.4MB), freight and passengers and source data (678KB)

Miscellaneous: Library (54KB), Standard codes (35KB), Socio-economic, GIS background datasets

For more information see the overview document (PDF, 79KB).

Updates

Users of the Infrastructure GIS and database should be aware that the approach taken to assembling data reflects the analytical needs of the work. For example, forecasting demand on links requires a fully-connected transport network (rather than one suitable for cartographic use). Demand data exists at various levels of aggregation with differing uses and accuracies. Spatial precision is suitable for project analysis.
