Yes, that's correct. When you try to flatten a spherical surface like the Earth onto a 2D map, distortions are inevitable due to the inherent differences in geometry. Different map projections exist to minimize these distortions, but no single projection can accurately represent all aspects of Earth's surface simultaneously.
Broken projection is a term used in cartography to describe distortions or errors in a map projection, which can result in inaccuracies when representing a three-dimensional object, such as the Earth, on a two-dimensional surface. These distortions can affect the shape, area, distance, or direction of geographic features on the map. The term highlights the inherent limitations of trying to represent a spherical object on a flat surface.
The Mercado projection is a map projection that preserves the shapes of continent to minimize distortion. It is often used to represent regions near the equator with less distortion in shape and direction.
accurate directions but has distorted sizes and distances
Making a map involves projecting the round globe surface onto a 2D flat surface to represent Earth's features accurately and in a way that can be easily understood. This process can lead to distortions in shape, size, or direction depending on the type of map projection used.
To transform degrees to coordinates, you typically need to use a projection system that maps spherical coordinates to a flat plane like a Cartesian coordinate system. One common way to do this is by using a projection such as the Mercator projection for mapping the Earth's surface coordinates to flat map coordinates. Software tools like GIS applications can help with this conversion.

The main problem is that the earth is approximately spherical and therefore maps covering large areas suffers from distortions due to projection from 3-D to 2-D.
That would depend on the type of map. A Mercator projection projects the Earth onto a cylinder, causing distortions at the poles. A "conic" projection projects the Earth onto a cone. And there are special purpose maps that project the Earth onto a plane.
This is called a map projection.
Cartographers an represent the spherical Earth on flat paper by making a projection, which is like casting shadows from the spherical world onto a flat piece of paper.
Projection
because there has to be some kind of distortion of earths spherical shape
Absense inaccuracies in carteography, the maps need to be projected onto a 2D surface for human use.As the area of the mapping grows the surface of the planet comes into play. We llive on a sphere and mapping a sphere to a flat plane creates distortions.EXAMPLE:two lines with 1 degree angle between them. that start at the north pole and travel to the south pole will get farther and farther apart until reaching the equator and then will get closer and closer together again as they approach the south pole.
Aspheric lenses have a more complex shape that varies across the surface, providing better image quality and reducing distortions compared to spherical lenses, which have a uniform curvature.
Spherical lenses have a uniform curvature across their surface, which can lead to distortions and aberrations in the image quality, especially towards the edges. Aspherical lenses, on the other hand, have a more complex surface that helps reduce these distortions and aberrations, resulting in improved optical performance and higher image quality.
Try taking the peel of an orange and laying it out flat so that all the edges meet up - you can't! Well the earth is also a ball and when you try and represent the curved surface on a flat piece of paper it would behave like the orange peel. To make a flat map you have to make a projection of the earths round surface (there are a number of ways of doing this) and this introduces a distortion.
