Calculating the Area of an Object for a Discrete Somatic Raster Data Set

Accurately calculating the area of an object from a discrete somatic raster data set can be a challenging task. A raster data set is a representation of the world, where the area is divided into pixels, and each pixel has a value that represents a surface attribute, such as elevation (Moore, 2020). In order to calculate the area of an object, it is necessary to determine the pixel values that correspond to the object of interest. This is usually done by creating a binary image, which assigns a “yes” or “no” value to each pixel depending on whether it is part of the object or not (McKendry, 2020). Once a binary image has been created, it is possible to count the number of pixels that represent the object, and then calculate the area of the object based on the resolution of the data set. To calculate the area, the number of pixels needs to be multiplied by the area of each pixel, which can be calculated by the equation A = (cell size)^2 (Khoury, 2018). The cell size is the resolution of the dataset, and it describes the size… Cont…
