Study Notes
Hydrographic Surveying History
- The oldest known navigational chart is the Carte Pisane, dating to the late 13th century, likely created in Genoa.
- Similar "portolan" charts were developed in Venice and Majorca, featuring rhumb lines connecting compass rose directions.
- 15th-century Portuguese and Spanish charts allowed travel to England and Flanders.
- "Caping the ship" method used written directions and previous soundings.
- Pierre Garcie of Rouen printed caping information in a "Routier de la Mer" with illustrations.
- Cornelius Anthonisz used woodcut blocks for early paper charts and Ptolemy's projection.
- Lucas Janszoon Waghenaer of Enkhuizen created copper plate engravings for charts around 1584. His "Spieghel der Zeevaerdt" comprised 45 charts of European coasts and introduced novel features like coastal outlines, better harbor approaches, depth indications, and buoy symbols.
- King Charles I of England commissioned Greenville Collins to survey British waters for nearly 11 years to create a coasting pilot and charts.
- Early charts were problematic in establishing longitude, needing shore marks and tide tables for accuracy.
- 17th-century French hydrographers established a national hydrographic office.
- 1919, an international conference emphasized standardization and led to the creation of an International Hydrographic Organization (IHO)
Importance of Hydrography
- Hydrography describes and measures sea and coastal features for navigation, research, and environmental protection.
- Hydrography is crucial for safe navigation and commerce by providing charts for accurate sea-based operations.
- Hydrography supports coastal zone management, including ports, coastal erosion control, and land reclamation.
- Accurate charts are required by the fishing industry to manage fishing activity, protecting crews and gear.
- Marine science, including bathymetry, ocean circulation and data is critical to research and safety measures. Inaccurate data can lead to major financial losses and environmental issues such as oil spills.
- It's also very important in Maritime Defence.
- Hydrographic data is a public good not easily provided by market forces and is essential for economic and commercial maritime operations, thus demanding greater consideration of this aspect, which should not be overlooked.
Coastal Zone Management
- Precise surveys of coastal areas are needed for large-scale projects, such as port construction and coastal erosion mitigation.
- Coastal zone management often involves multiple users, so this survey information requires GIS and Geographic information systems to assist in decision-making.
Recreational Boating and Tourism
- Digital charts are becoming very common for leisure boaters and recreational activities now.
- Hydrographic surveys support the growing cruise ship tourism, a lucrative global industry.
