What images do not take into account the sphericity of the Earth?

As you know, the Earth is a ball. If you look at the globe, you can see roughly what our planet looks like in miniature. But the maps do not take into account the sphericity of the earth, since they are depicted on a plane. For example, in the region of the equator, the calculations will be as accurate as possible, however, the closer to the pole, the less accurate the calculations will be, and because the sphericity of the planet was not taken into account. The smaller the scale, the larger the map, the less errors in calculating the values.
