Sectional charts are in 1:500,000 scale and are named for a city on the map. The Federal Aviation Administration (FAA) in the United States publishes over 50 charts covering the continental United States, Alaska, and Hawaii. Sectional charts are published by the National Aeronautical Navigation Services Group of the FAA.
On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points. Most charts include a compass rose depicting the variation between magnetic and true north. However, the use of the Mercator projection has drawbacks. This projection shows the lines of longitude as parallel.
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...
An Electronic Navigational Chart (ENC) is a digital representation of a real-world geographical area for the purpose of Marine navigation.Real-world objects and areas of navigational significance, or to a lesser degree - informational significance, are portrayed through Raster facsimiles of traditional paper charts; or more commonly through vector images, which are able to scale their relative ...
Naming all 32 points on the rose is called "boxing the compass". The 32-point rose has 11 1 ⁄ 4 ° between points, but is easily found by halving divisions and may have been easier for those not using a 360° circle. Eight points make a right angle and a point is easy to estimate allowing bearings to be given such as "two points off the ...
Plan of San Diego Bay in the 1940s, making distinctions between anchorages and moorings. An anchorage is a location at sea where ships can lower anchors.. Anchorages are where anchors are lowered and utilised, whereas moorings usually are tethering to buoys or something similar.
Point and figure (P&F) is a charting technique used in technical analysis.Point and figure charting does not plot price against time as time-based charts do. Instead it plots price against changes in direction by plotting a column of Xs as the price rises and a column of Os as the price falls.
Admiralty Gnomonic Chart of the North Atlantic, used to find the shortest track (portion of a great circle) between two points. A straight line is drawn between the two points on this chart, and the resulting great circle track is transferred to a Mercator chart, plotting the latitudes of the points of intersection of the track with the several ...
