In order to read a chart, you interpret longitude and latitude lines to determine your coordinates, which is your position. You have to understand and interpret different symbols like depth, scale, and navigation marks. Using these symbols, you find a safe course and plot it on the chart.
Horizontal Scale: Natural scale at for example 40° 15',0 latitude where the horizontal scale can be used for measuring distances and were the chart scale is true. GPS compatibility: Most charts neither have the precision nor the resolution to fully use the (differential) GPS positioning potential.
On Chart 3, on the middle of either side of the chart you will find written 46° 00' north. This line, which forms part of a circle all the way around the World, joins all the points which are 46 degrees north of the Equator (° is the symbol for degrees).
At the equator a degree of longitude is approximately equal in length to a degree of latitude. As the distance from the equator increases, degrees of latitude remain approximately the same, while degrees of longitude become progressively shorter. Since degrees of longitude appear everywhere the
10 paź 2024 · Latitude and longitude are measurements of location on the globe. To find latitude on a map, look for a series of evenly-spaced horizontal lines with numbers along the edges. Alternatively, to find longitude, look for a series of vertical lines from the North Pole to the South Pole.
27 kwi 2024 · Latitude and longitude comprises a grid system of lines encircling the globe and is used to determine the locations of points on the earth. Lines of latitude, also called parallels, run east - west. Latitude lines always run parallel to each other, and hence, they are always an equal distance apart.
24 maj 2024 · The latitude of a particular location is the distance, measured in degrees, between that place and the equator along a meridian, or line of longitude. The equator is 0 o latitude, and the North and South Poles are located at 90 o north and 90 o south latitude respectively.
