Which of the following describes the best practice for handling raster images in georeferencing?

Using multiple methods to ensure flexibility is indeed a best practice for handling raster images in georeferencing. This approach allows for the accommodation of different data types, resolutions, and source characteristics. By employing various techniques, practitioners can apply the most suitable method for each dataset, whether it involves controlling points, transformations, or interpolation methods. This flexibility is crucial, as each dataset may require a unique approach for accurate alignment within the geographic coordinate system.

Moreover, flexibility enhances the overall accuracy and reliability of the georeferencing process. When multiple methods are available, a GIS analyst can choose the most effective one based on the specific quality, accuracy, and resolution of the raster images involved. This results in a more robust georeferencing output, ensuring that the images are correctly aligned with the geographic features they represent.
