Nautical Charts In Florida Enhance Mariner Safety

By Jillian French


The information included on nautical charts Florida are useful for boaters and other mariners. A graphical representation of seas and coastal areas can provide important data. Some maps include water depths, land heights, seabed features, coastal details and navigational hazards. Additionally, many also incorporate information on tides and currents, the Earth's magnetic field and the locations of man-made and natural navigational aids. Structures such as harbors, bridges, break-waters and buildings are also often identified.

These maps are essential tools for mariners. Many countries require vessels to carry them on-board. In addition to printed materials, electronic navigational aids are often used. Many sailors use on-demand maps. They can be downloaded, and provide the most current information as they are constantly updated. These are effective in communicating potentially dangerous situations and warnings to mariners.

The information for the maps is gathered through hydrographic surveys. The lengthy process involves echo-location. The technique measures seabed depths and other features. When potential hazards are discovered, such as ship-wrecks, additional safety measures are taken. The questionable locations are swept with submerged wires. This can help ensure that no hidden obstructions, such as ship masts, pose harm to passing vessels.

National hydrographic offices have been set-up in many locations around the globe. Each country's organization is responsible for the official release of marine maps. Unofficial publications are also released by commercial entities. These are often tailored to meet the needs of specific mariners, such as details for yachts. An International Hydrographic Organization has been organizing the release of global, inter-connected maps.

Many organizations offer free maritime maps. BlooSee is a global mapping site, with a mobile app, and a social networking site. They offer sea-lovers many details about the United States, New Zealand, Brazil and the Pacific Ocean. Their content is contributed by kayakers, sailors, divers, surfers and other members of the ocean community.

In connection with OpenStreetMap, the OpenSeaMap project uses images from Google maps. They incorporate data from many hydrographic surveys into a layered projection. Other features can be accessed online, such as voyage planning, route monitoring, and distance and bearing calculations.

TeamSurv is a crowd-sourced project supported by global mariners. Seafarers upload their global positioning satellite and depth sounder data, compass headings and surface temperatures. This data is collected on a server which performs quality checks. After the information is verified, it is accessible online.

Nautical charts Florida provide a wide array of valuable information. Global resources, new technology and constant updating make these maps especially relevant and useful. Read more about: nautical charts florida
