it can only use in island only,because the Mercator chats is only can see a small island.
Mercator charts are not suitable for representing the polar regions because they distort areas and distances as they get closer to the poles. This distortion becomes significant in the polar regions, leading to inaccurate representations of landmasses and navigational inaccuracies. Polar projections, like the Azimuthal equidistant or stereographic projections, are more appropriate for mapping polar areas due to their accuracy near the poles.
A cylinder is used to create the Mercator Projection. The Earth's surface is projected onto the cylinder, which is then unrolled to create a flat map. This projection results in distortions in the polar regions.
The Mercator projection is commonly used in navigation because it preserves straight lines, which facilitates course plotting. It is also widely used for world maps in education and cultural contexts due to its familiarity and the way it emphasizes high-latitude countries.
Mercator:Mercator projection works very poorly in polar regions and becomes undefined at the north and south poles. Historically Mercator is interesting because it is one of the oldest map projections to be used. Christopher Columbus used the Mercator projection in his travels to the new world. This projection is often used in navigation because any straight line is a rhumb line (a line of constant direction). Parallels of latitude and longitude are straight. Features increase in size as the map approaches the poles. Areas and shapes of large areas are distorted. Distortion increases away from the equator and is extreme in polar regions. However, being a conformal projection, angles and shapes within any small area are essentially true.
The Mercator projection is the standard for nautical navigation.

Mercator
A mercator projection is defined as a projection of a map of the world onto a cylinder in such a way that all the parallels of latitude have the same length as the equator, used especially for marine charts and certain climatological maps. Congo, as depicted in mercator projection, is small.
its used best as a gps
Mercator Sailing refers to technique used to deal with the problem of course and distance in the maritime world.
You might consider using the Mercator projection, which preserves straight lines and angles. This projection is commonly used for nautical charts and provides an easy way to visualize shipping routes and compass headings accurately on a global scale.
It still is used.
