Frequently Asked Questions

What are Combat Charts/Littoral Planning Charts and how are they used in naval operations?

Combat Charts/Littoral Planning Charts are specialized charts that combine the characteristics of a map and a chart to represent both land and sea areas. They are primarily used in naval operations, particularly amphibious operations. These charts depict an equal amount of sea and land in a specific area of interest. They use a standard scale to provide optimal operational coverage and a smooth transition from nautical chart coverage to 1:50,000 topographic maps. Combat Charts play a crucial role in developing a database for modern littoral warfare, including tactical maneuver from the sea and logistics over the shore.

Why are Combat Charts being replaced by the Littoral Planning Chart?

The Combat Charts are being replaced by the Littoral Planning Chart (LPC) to ensure the outdated charts are phased out and the LPC becomes the new standard. The LPC incorporates the use of nautical charts for tactical purposes, in addition to their traditional use for ensuring safety at sea. This transition ensures that the charts used in naval operations are updated and standardized.

How can I obtain hydrographic stock numbers for Combat Charts and Littoral Planning Charts?

To obtain hydrographic stock numbers for these charts, you can use the NGA Reference Number/National Stock Number (NRN/NSN) Lookup and Download. This resource will provide you with the necessary information to access the specific charts you require for your needs.

Why is mapping the seafloor’s bathymetry important for yachts?

Mapping the seafloor’s bathymetry is important for yachts because outdated depth information on nautical charts can pose a risk to navigation. Some of this data may be over 150 years old, making it unreliable for safe sailing, especially in exotic locations. Yachts need reliable navigation sensors and charts to ensure their safety while at sea.

What is crowdsourcing bathymetry data, and how can yachts contribute?

Crowdsourcing bathymetry data is a global initiative called Seabed 2030, which aims to map the world’s oceans’ seafloor. Yachts can contribute to this initiative by providing their depth and position observations. Measurements collected by the yachting community are valuable contributions to this effort and help create more accurate maps of the seafloor. Participating vessels may be equipped with data loggers or advanced sensors to record bathymetry data.

How does mapping the seafloor’s bathymetry benefit scientific research and commercial purposes?

Mapping the seafloor’s bathymetry benefits scientific research by providing crucial information for understanding ocean circulation, habitat mapping, sediment transport, environmental changes, fishing resources, harmful algal blooms, tsunami forecasting, and more. It also contributes to commercial purposes such as offshore wind development, mineral and energy exploration, pipeline routing, port and harbor infrastructure construction, and sustainable blue economy planning. Accurate bathymetric maps support the safe and efficient operation of the marine transportation system and support overseas and foreign trade.
