Understanding map projections is essential due to the need to represent the Earth’s spherical surface on 2-dimensional maps. The process entails projecting the surface to a 2D image, resulting in distortions. Various map projections exist, each minimizing distortions in different aspects. Different popular projections such as Orthographic, Mercator, Transverse Mercator, Universal Transverse Mercator, Lambert Conformal…

The article explains the Sobel operator, a kernel used in image processing for edge detection in Convolutional Neural Networks. The operator consists of two kernels for calculating the gradient in the horizontal and vertical directions. It is useful for detecting edges in grayscale images by approximating the gradient of image intensity at each pixel.
