How do you calculate the area of an object for a discrete somatic raster data set?

Calculating Area for an Object in a Discrete Data Set of Somatic Rster Data

It can be difficult to calculate the exact area of an object using a discrete raster data collection. A raster dataset is a visual representation of the entire world. The area is broken down into pixels and each pixel contains a value which represents an attribute on the surface, like elevation (Moore 2020). To calculate an object’s area, you need to find the values of the pixels that correspond with the object. 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). After creating a binary image, you can count how many pixels represent an object and calculate its area based on that data set. The area can be calculated using the formula A = (cell size2) (Khoury 2018, to calculate). Cell size refers to the data’s resolution.
