Charts and maps

The National Maritime Museum collections contain more than 100,000 sea charts and maps dating from the medieval period to the present day. They document the results of exploration and discovery and show how techniques of navigation and surveying developed. Many were owned by naval officers and politicians and were used to plan and record the events which have become maritime history.

The collections are not exclusively British and although they concentrate on charting the seas and coastlines, land maps are also included. Together they illustrate the work of the leading hydrographers and cartographers throughout the history of charting and mapmaking.

Hydrography: introduction

Portulan Chart of the Mediterranean, North Atlantic and Black Sea Portulan Chart of the Mediterranean, North Atlantic and Black Sea Charts represent the world's water-covered regions as aids to navigation. They are generally drawn on Gerard Mercator's projection (first introduced in 1569), which transforms the curved surface of the earth on to a flat plane.

The earliest portulan charts were prepared on vellum (sheep or goatskin). These concentrated on the Mediterranean. Later Italian, Spanish and Portuguese charts included new information resulting from the voyages of exploration of the late-15th and early-16th centuries.

Printed charts replaced portulan charts in the 17th century. The Dutch dominated the hydrography market and published many fine sea atlases. France and Britain next became major forces in chartmaking. Both established naval hydrographic offices, France in 1720 and Britain in 1795.

The British contribution to hydrography was highlighted by the voyages of discovery made by Captain James Cook between 1768 and 1780. Britain led the charting industry during the 19th century.

Research opportunities

The collections offer significant opportunities for research into both more traditional areas such as exploration and discovery, naval operations, navigation and mercantile travel as well as emerging areas including cultural geography, post colonial studies and marine environmental management.

To help with research the Museum subscribes to the following journals and newsletters related to maps and charts:

  • Imago Mundi
  • IMCoS Journal

Collections online is a website that provides access to over 5500 records and images from the Museum's collections including 480 charts and maps. Other objects include: ceramics, coins and commemorative medals, edged weapons, firearms, globes, jewellery, quadrants and sundials. Visit the Collections Online website


Port is an online catalogue developed to promote a more interactive approach to the use and interpretation of maritime information. Resources contained on Port include listings of organizations and key stakeholders, an inventory of courses and conferences, key sites and other relevant material, which may be browsed by subject category or historical period. A number of the subject categories are highly appropriate for the charts and maps collection, including navigation, recreation and sport, travel and exploration and underwater archaeology.

The marine environment collection
The hydrography section is closely linked to the Museum's developing marine environment collection. This collection has four inter-linked themes

  • The physical ocean
  • Society and the sea
  • The threatened sea
  • Science and the sea

These form the key components of humankind's contemporary relationship with the oceans and highlight the need for an integrated understanding of this important and fascinating subject. Many of the maps and charts are integral to aspects of these key themes. For example, the British Admiralty charts are valuable tools for underwater navigation and exploration, in the mapping and interpretation of recent environmental change and for international relations and boundary studies.


Oceanographic related publications
The Museum holds an extensive collection of publications related to oceanography. These are currently held in store at the main Museum site and may be seen in the Caird Library. These texts may be used in conjunction with a number of the charts and maps mentioned above, especially in relation to the reconstruction and prediction of coastal and ocean environmental changes.
